Hello Michele,

to use the backlight via sysfs you will have to export it first.

Go to the directory of the PWM you want to use
cd /sys/class/pwm/pwmchip0/

and export it

echo 0 > export

Please note that this will only work if this PWM is not claimed by another device like backlight.

Now you should see a new subdirectory pwm0

ls pwm0/

There you shloud be able to set the period in nanosecond,

echo 5000000 > pwm0/period

the duty cycle in nanoseconds,

echo 2500000 > pwm0/duty_cycle
the polarity (this is only possible if the device is disabled),

echo "inversed" > pwm0/polarity

echo "normal" > pwm0/polarity

and enable/disable the device.

echo 1 > pwm0/enable

echo 0 > pwm0/enable

If you need an example on how to control pwm via a C-programm please see the pwm-example in your build directory of your release, e.g:

fsimx6-B2020.04/build/examples-fus-B2020.04/pwm/pwm.c

This is because of UBIFS overhaed.

UBIFS needs 17 LEBs for metadata.

So for your 124 KiB LEB size this means 2.108 KiB which adds up to your 5MB partition size.

Your F&S support team

Hello Carles and welcome to the forum,

for creating an UBIpartition in Uboot you can refer to chapter 5.5 UBI Concepts of the Linux OnFS Boards documentation.

https://www.fs-net.de/assets/d…n/LinuxOnFSBoards_eng.pdf

Quote

[…]

# Create UBI with volume rootfs on partition TargetFS

nand erase.part TargetFS

ubi part TargetFS

# 5MiB for logs

ubi create logslf 0x00500000

ubi create rootfs

This seems fine so far. Please keep in mind that erasing a valid UBI partition in an update-script with nand erase.part TargetFS also erases the list of erase count and might not be a good idea. For more information please see chapter 5.5 UBI Concepts of the Linux OnFS Boards documentation. If you have already installed a rootfs run ubi remove rootfs instaed.

Quote

# Load root filesystem and store in UBI volume rootfs

load ${updatedev} $loadaddr rootfs.ubifs

ubi write $loadaddr rootfs $filesize

# Set default configuration: kernel and fdt from NAND, rootfs from ubifs

run .kernel_nand

run .fdt_nand

run .rootfs_ubifs

Should I add a “run .logs_ubi” in
the script?

Display More

No, this is only necessary to tell the Uboot to load the rootfile system from the NAND flash.

Quote

Also, when the system with this udate.scr is created I notice that the 5MB for the logs partition is reserved and in the location /dev there is a device called ubi0_1 and ubi0_0 (don’t really know if one of them is the logs partitions).

I’m pretty new with partitions so I’m a little bit lost, I know from your pdfs that as I have it now I already have the partition created but what it’s missing is putting a filesystem inside. I don’t really know neither how to create this filesystem nor what type, because for the logs I would need an empty filesystem (?).

ubi0_0 should be your logs partition as you created it first.

If you mount an empty UBI partition an ubifs will automatically get created. Just run

mount -t ubifs /dev/ubi0_0 /mnt/

And you should be able to read/write to it like to your rootfs.

I hope this helps.

Best regards and have a great day

Can something be done? As I mentioned my devboard is older version - so this might be a problem here.

I transferred these files from my build folder

Hello guser,

I investigated your problem and indeed, it seems that your old board version and the current release do not fit.

Also, on i.MX8 the Uboot gets loaded by the SPL (Secondary Boot Loader), which does not get replaced if you replace only the Uboot.nb0.

Replacing the SPL is quite complicated at the moment, especially on an old board revision like yours, but can be done if you really need to.

Your new PicCoreMX8MM is on its way to you, so I would recommend working with the new revision, but if you are on a tight schedule I can assist you in replacing the SPL.

Hello,

F&S PicoCoreMX6UL Buildroot Release (14.08.2020)

Please see the file

doc/FSiMX6UL_FirstSteps_eng.pdf

for a description of how everything is installed and used.

This release extends the fsimx6ul-B2019.11 release by the support for

eMMC as boot device for the PicoCoreMX6UL.

It also provides a new version of the Nboot.

The rest of the release is equal to fsimx6ul-B2019.11.

!!! Attention !!

This release has just been tested with the PicoCoreMX6UL and supports only

the PicoCoreMX6UL!

!!! Attention !!

These are the highlights of the picocoremx6ul-B2019.11 release:

- The PicoCoreMX6UL now supports eMMC as boot device

- New partition layout for eMMC Boot- and User-partitions

(See Linux on F&S Boards Appendix)

- The Uboot is now located in the system partition of the user area of the eMMC.

It can be exchanged like kernel and devicetree.

- UMS (USB Mass Storage) support in Nboot and Uboot. The system partition of the

board can be mounted via UBS-Device port like a USB stick and Uboot, Linux Kernel

and Devicetree can be exchanged via drag and drop.

- Special Nboot and Uboot for eMMC support.

To build the right Uboot run "make fsimx6ul_mmc_defconfig" first.

Make sure to install the right Nboot and Uboot binaries. They are marked with

an "_mmc_" in their name.

These are the highlights of the fsimx6ul-B2019.11 release:

This is the next regular major release for fsimx6ul. fsimx6ul is the

software for all boards from F&S that are based on the i.MX6-UltraLite

and i.MX6ULL CPUs from NXP (or i.MX6UL and i.MX6ULL for short).

Currently these are the modules efusA7UL, PicoCOM1.2 and

PicoCoreMX6UL. Further boards may be added to this family in the

future. All these boards can work with software that is created from

this release package.

This release brings new versions to all parts of the software stack.

Here are some highlights of this release.

1. New version numbering

We have changed the way how we name versions. In the past we had a

version number made up of a major part m and a minor part n. Then we

used Vm.n for Buildroot releases and Ym.n for Yocto releases. Release

versions were counted individually for each CPU architecture. But then

a "new" CPU type unfortunately had a smaller version number than an

"old" CPU, even if the code was coming from the same sources or was

even newer. This caused some irritations and misunderstandings of what

release is actually the newest.

So from now on we will use the year and month of the release instead,

preceeded by a 'B' for Buildroot releases and a 'Y' for Yocto

releases. For example the "B2019.11" of this release indicates a

Buildroot based release from November 2019.

2. Support for new board PicoCoreMX6UL

This is the first regular release that supports PicoCoreMX6UL. The

PicoCore is only 40mm x 35mm but is a very powerful System-on-Module

with many I/Os.

3. New U-Boot 2018.03

We have a considerably newer U-Boot now. One of the main new features

is display support, so basically U-Boot can now be used to show a

splash screen.

U-Boot will also show more information about the CPU type now, for

example temperature range, possible speed, etc. The command "clocks"

will show much more information about internal clock rates. And USB

storage devices are detected faster and more reliably than before.

U-Boot has experienced quite a lot of internal restructuring. For

example it now also supports configuration via a Kconfig menu, similar

to Linux kernel and Buildroot. After configuration with

simply call

to show the menu. There you can select and de-select entries or move

to sub-menus.

Moving all configuration options from the previous header file to this

menu is a long-term and still on-going process. So not all features are

available in the menu, yet.

U-Boot is now compiled and running in THUMB mode. This saves space

that is needed for all the display code.

4. New Linux kernel 4.9.88

The Linux kernel is now based on 4.9.88. By default, we are using the

zImage format of the kernel now, not the uImage format as before. Here

are some of the new features since the previous kernel 4.1.15.

- Improvements and optimizations in memory management, for example

better heap and page management (tmpfs, shmem), better protection

against attacks by implementing stack, heap and memory

randomization.

- Performance optimizations for the network stack, like faster TCP

connections, quick killing of hanging network links, more features

for the packet filter (firewall), smaller latencies on WLAN.

- Optimizations in block layer, for example better Device Mapper for

LVM, improved parallel access to directories, more efficient access

to SSDs, parallel access for NFS, kernel support for file copy,

server-side copy for CIFS, NFS, XFS, support for hard discs with

host-managed SMR (Shingled Magnetic Recording).

- Optimizations on file systems (NTRFS, EXT4, F2FS, NFS, XFS,

Overlayfs, Ceph), new cluster filesystem Orangefs

- Many improvements in graphics stack, like DRM (Direct Rendering

Manager), new open source graphics driver etnaviv for Vivante

graphics on i.MX CPUs (etnaviv = vivante backwards)

- Better load balancing of processes to CPU cores, new cgroups v2,

improved power and frequency handling, new cpufreq governor

schedutil.

- New GPIO infrastructure not using sysfs, supposed to be faster.

- Support for USB SuperSpeedPlus (USB 3.1).

- Many many new and improved drivers for WLAN chips, touch

controllers, audio codecs, cameras, MMC/SD cards, etc.

Of course there are also many changes for other CPU types (like x86)

and other graphics cores (like AMD, Nvidia, Intel) but these are not

of interest here.

5. Buildroot 2019.05.1

Buildroot 2019.05 has many many updated packages, for example Qt-5.12,

busybox-1.30.1, xserver-1.20.5 and gstreamer-1.16.0. We actually use

buildroot-2019.05.1, which is a newer version that already has some

more fixes.

6. New toolchain fs-toolchain-8.3-armv7ahf

Our new toolchain is now based on gcc-8.3 that fully supports C++14

and has basic support for C++17 and even some experimental support for

C++2a.

This toolchain is now a 64-bit toolchain, i.e. it will not run on PCs

(or VMs) with a 32-bit Linux anymore. The default output of the

toolchain is of course still ARMv7 code for 32 bit ARM CPUs like

Cortex-A7 or Cortex-A9, as in i.MX6UL or i.MX6SX.

This toolchain also fixes a bug in the calling convention for ARM CPUs

that was introduced in gcc-5.x and prevented some code optimizations.

Many software packages now depend on a compiler that has this bug

fixed. For example our new u-boot-2018.03 will produce bad code if

compiled with a toolchain before gcc-6.0. Qt5-webengine will not

compile with a toolchain before gcc-8.0. So please use this new

toolchain together with the code of this release.

7. Default LVDS display replaced

The ChiMei LVDS display that F&S used to ship with some Starter Kits

is not available anymore. We will ship a different display from now

on. Therefore we also changed the default settings for LVDS in the

Linux device trees so that upcoming customers will have a working

display.

If you still need the previous settings, simply remove the two comment

slashes at the beginning of the following line in the device tree and

re-build the device tree. Then the old settings will be active again.

//#define DISPLAY_LVDS_CHIMEI

8. New driver for Silex WLAN

In the past, the Silex WLAN driver was only available as a binary

package. Now, for Linux 4.9.88, the driver is an open-source version

that is built as part of Buildroot. This means you are more flexible

with changes of the networking stack or specific configurations of the

driver. A second package provides the firmware files. Please use

exactly these, they contain modifications that are specifically

adapted to our boards.

Unfortunately we did not get patches for a newer bluez version in

time. So Bluetooth is still based on bluez-5.39. Maybe we can improve

this with a patch later.

9. Documentation

In the past, the documentation that was included in the release

package itself was often superseded by newer versions on our website.

But people continued to use the outdated version of the release,

causing unnecessary complications.

To avoid this, from now on only the software related documentation is

directly included in the release and we have added a chapter to

FSiMX6UL_FirstSteps_eng.pdf that contains direct links to the

appropriate resources on our website. There you can download the

newest versions of hardware documentations, schematics, layout files,

certificates, accessories, add-ons, adapters and similar things.

The software documentation is completely reworked. The

FSiMX6UL_FirstSteps_eng.pdf document now really only shows a basic

introduction to the work with boards of the fsimx6ul architecture. And

there is a new document LinuxOnFSBoards_eng.pdf that shows a more

in-depth view of a Linux system in general and of the F&S versions of

NBoot, U-Boot, Linux and Buildroot in particular. This is still work

in progress, some chapters are not fully done yet and will be revised

in the future. Check our website from time to time to see if there is

a newer version of this document.

=========================================================================

The following list shows the most noticable changes in this release in

more detail since our last regular i.MX6UL release (not counting the

intermedieate release for PicoCoremX6UL). Please note that the source

code is also used for other platforms. This is why you will also find

references to other CPU types and F&S boards here in the changelog.

PicoCOMA7 Buildroot Release B2019.11.1 (19.08.2020)

The minor release picocoma7-B2019.11.1 renames the delivered binaries from *-fsimx6ul-* to *-picocoma7-*.

The rest of the release is identical to the picocoma7-B2019.11 release.

PicoCOMA7 Buildroot Release (30.07.2020)

Please see the file

doc/FSiMX6UL_FirstSteps_eng.pdf

for a description of how everything is installed and used.

This is a minor release for the PicoCOMA7 based on the fsimx6ul-B2019.11 release.

!!! Attention !!!

Please notice that it is only tested with the PicoCOMA7 and only supports the PicoCOMA7 .

!!! Attention !!!

This release adds support for the PicoCOMA7 to the fsimx6ul-B2019.11 release.

Here are some highlights of the fsimx6ul-B2019.11 release.

. New version numbering

We have changed the way how we name versions. In the past we had a

version number made up of a major part m and a minor part n. Then we

used Vm.n for Buildroot releases and Ym.n for Yocto releases. Release

versions were counted individually for each CPU architecture. But then

a "new" CPU type unfortunately had a smaller version number than an

"old" CPU, even if the code was coming from the same sources or was

even newer. This caused some irritations and misunderstandings of what

release is actually the newest.

So from now on we will use the year and month of the release instead,

preceeded by a 'B' for Buildroot releases and a 'Y' for Yocto

releases. For example the "B2019.11" of this release indicates a

Buildroot based release from November 2019.

2. Support for new board PicoCoreMX6UL

This is the first regular release that supports PicoCoreMX6UL. The

PicoCore is only 40mm x 35mm but is a very powerful System-on-Module

with many I/Os.

3. New U-Boot 2018.03

We have a considerably newer U-Boot now. One of the main new features

is display support, so basically U-Boot can now be used to show a

splash screen.

U-Boot will also show more information about the CPU type now, for

example temperature range, possible speed, etc. The command "clocks"

will show much more information about internal clock rates. And USB

storage devices are detected faster and more reliably than before.

U-Boot has experienced quite a lot of internal restructuring. For

example it now also supports configuration via a Kconfig menu, similar

to Linux kernel and Buildroot. After configuration with

make fsimx6ul_defconfig

simply call

make menuconfig

to show the menu. There you can select and de-select entries or move

to sub-menus.

Moving all configuration options from the previous header file to this

menu is a long-term and still on-going process. So not all features are

available in the menu, yet.

U-Boot is now compiled and running in THUMB mode. This saves space

that is needed for all the display code.

4. New Linux kernel 4.9.88

The Linux kernel is now based on 4.9.88. By default, we are using the

zImage format of the kernel now, not the uImage format as before. Here

are some of the new features since the previous kernel 4.1.15.

- Improvements and optimizations in memory management, for example

better heap and page management (tmpfs, shmem), better protection

against attacks by implementing stack, heap and memory

randomization.

- Performance optimizations for the network stack, like faster TCP

connections, quick killing of hanging network links, more features

for the packet filter (firewall), smaller latencies on WLAN.

- Optimizations in block layer, for example better Device Mapper for

LVM, improved parallel access to directories, more efficient access

to SSDs, parallel access for NFS, kernel support for file copy,

server-side copy for CIFS, NFS, XFS, support for hard discs with

host-managed SMR (Shingled Magnetic Recording).

- Optimizations on file systems (NTRFS, EXT4, F2FS, NFS, XFS,

Overlayfs, Ceph), new cluster filesystem Orangefs

- Many improvements in graphics stack, like DRM (Direct Rendering

Manager), new open source graphics driver etnaviv for Vivante

graphics on i.MX CPUs (etnaviv = vivante backwards)

- Better load balancing of processes to CPU cores, new cgroups v2,

improved power and frequency handling, new cpufreq governor

schedutil.

- New GPIO infrastructure not using sysfs, supposed to be faster.

- Support for USB SuperSpeedPlus (USB 3.1).

- Many many new and improved drivers for WLAN chips, touch

controllers, audio codecs, cameras, MMC/SD cards, etc.

Of course there are also many changes for other CPU types (like x86)

and other graphics cores (like AMD, Nvidia, Intel) but these are not

of interest here.

5. Buildroot 2019.05.1

Buildroot 2019.05 has many many updated packages, for example Qt-5.12,

busybox-1.30.1, xserver-1.20.5 and gstreamer-1.16.0. We actually use

buildroot-2019.05.1, which is a newer version that already has some

more fixes.

6. New toolchain fs-toolchain-8.3-armv7ahf

Our new toolchain is now based on gcc-8.3 that fully supports C++14

and has basic support for C++17 and even some experimental support for

C++2a.

This toolchain is now a 64-bit toolchain, i.e. it will not run on PCs

(or VMs) with a 32-bit Linux anymore. The default output of the

toolchain is of course still ARMv7 code for 32 bit ARM CPUs like

Cortex-A7 or Cortex-A9, as in i.MX6UL or i.MX6SX.

This toolchain also fixes a bug in the calling convention for ARM CPUs

that was introduced in gcc-5.x and prevented some code optimizations.

Many software packages now depend on a compiler that has this bug

fixed. For example our new u-boot-2018.03 will produce bad code if

compiled with a toolchain before gcc-6.0. Qt5-webengine will not

compile with a toolchain before gcc-8.0. So please use this new

toolchain together with the code of this release.

7. Default LVDS display replaced

The ChiMei LVDS display that F&S used to ship with some Starter Kits

is not available anymore. We will ship a different display from now

on. Therefore we also changed the default settings for LVDS in the

Linux device trees so that upcoming customers will have a working

display.

If you still need the previous settings, simply remove the two comment

slashes at the beginning of the following line in the device tree and

re-build the device tree. Then the old settings will be active again.

//#define DISPLAY_LVDS_CHIMEI

8. New driver for Silex WLAN

In the past, the Silex WLAN driver was only available as a binary

package. Now, for Linux 4.9.88, the driver is an open-source version

that is built as part of Buildroot. This means you are more flexible

with changes of the networking stack or specific configurations of the

driver. A second package provides the firmware files. Please use

exactly these, they contain modifications that are specifically

adapted to our boards.

Unfortunately we did not get patches for a newer bluez version in

time. So Bluetooth is still based on bluez-5.39. Maybe we can improve

this with a patch later.

9. Documentation

In the past, the documentation that was included in the release

package itself was often superseded by newer versions on our website.

But people continued to use the outdated version of the release,

causing unnecessary complications.

To avoid this, from now on only the software related documentation is

directly included in the release and we have added a chapter to

FSiMX6UL_FirstSteps_eng.pdf that contains direct links to the

appropriate resources on our website. There you can download the

newest versions of hardware documentations, schematics, layout files,

certificates, accessories, add-ons, adapters and similar things.

The software documentation is completely reworked. The

FSiMX6UL_FirstSteps_eng.pdf document now really only shows a basic

introduction to the work with boards of the fsimx6ul architecture. And

there is a new document LinuxOnFSBoards_eng.pdf that shows a more

in-depth view of a Linux system in general and of the F&S versions of

NBoot, U-Boot, Linux and Buildroot in particular. This is still work

in progress, some chapters are not fully done yet and will be revised

in the future. Check our website from time to time to see if there is

a newer version of this document.

=========================================================================

The following list shows the most noticable changes in this release in

more detail since our last regular i.MX6UL release (not counting the

intermedieate release for PicoCoremX6UL). Please note that the source

code is also used for other platforms. This is why you will also find

references to other CPU types and F&S boards here in the changelog.

Many .NET Framework applications can also be executed on Linux systems by using the cross-platform framework Mono.

Mono is an open-source implementation of the .Net framework, sponsored by Microsoft. It currently supports most of the .NET libraries up to version 4.7 except WPF, WWF, and with limited WCF and limited ASP.NET async stack.

For GUI applications Mono offers its own implementation of System.Windows.Forms. It is based on X11, so the possible graphical backends of the F&S-Images are limited to X11 and Xwayland.

Mono does not offer any native libraries to access Linux hardware peripheries like I2C or SPI. If you need to access these in your application, please contact F&S for support to create these libraries.

You can test if your .NET application is portable to Linux by adding Mono to the latest F&S Buildroot and Yocto releases and run your application.

A tutorial of how to add Mono to your board image and how to run your .NET application can now be found at the Document tab of your board on the F&S Website under

Linux -> Mono on F&S Boards.pdf

Hello,

there seems to be an issue with the imx-gpu-viv package and the Xservers 2D driver glamor.

As NXP disables glamor in their Yocto reference release, we should do the same.

I attached a patch to do so.

Please put it into your buildroot directory buildroot-2019.05.3-fsimx6-B2020.04 and run

Your F&S support team

Hello,

we do not have a patch for kernel 4.1.15.

However, the issue is fixed in our current release fsimx6-B2020.04, which is based on linux kernel 4.9.88.
If possible, please update to this release.

Your F&S Support Team

Hello,

if you think that the threshold is set correctly by default you can try to remove the threshold parameter from the device-tree.

This should prevent the parameter from being set by the driver.

Your F&S Support Team

Glad to hear that.

Hopefully, this solution will do until NXP releases a fix for this bug.

Your F&S Support Team

Hello,

you are right, downgrading the imx-gpu-viv driver seems to be a bigger issue.

A quick hotfix for your problem would be, to add a small scaling to your rotation.

It seems to use a different hardware acceleration, which is not affected by the driver bug.

In general, adding a displayrotation is a performance expensive operation. Could you add your rotation to a higher level like the QT5 application?

Your F&S Support Team

Hello,

we are currently using the 6.2.4 imx-gpu-viv driver in our releases.

You can try to downgrade your imx-gpu-viv driver to version 5.0.11 like suggested in the NXP-post.

Replace the files at:

package/freescale-imx/imx-gpu-viv

with the files attached to this post and rebuild your rootfs.

Alternatively you could try to switch to Wayland as graphical backend. It should work there.

Your F&S Support Team

Hello,

can you stop in Uboot and enter commands there?

Which Kernel version and rootfile-Image are you using?

Your F&S Support Team

Hello Daniel,

for a new LCD-Display you will have to add an entry to the struct lcdif_modedb at

drivers/video/fbdev/mxc_lcdif.c

with the following parameters:

Additionally, you need to adjust your device tree file efusa9*.dts

#define CONFIG_EFUSA9_LCD_BPP <bits-per-pixel>

#define CONFIG_EFUSA9_LCD_PIX_FMT "<Pixel format>

#define CONFIG_EFUSA9_LCD_MODE_STR "<'name'-from-lcdif_modedb-entry"

You will have to rebuild and replace kernel and device tree.

Fix: No login tty on non-fus images

Unfortunately, there is an issue with the login for all non-fus images.

If you are trying to run an image that does not come from the fus layer, e.g the core-image-minimal, you will not get a login-tty on your debug console.

This is because with this release you can set the login in uboot, by setting the "login" environment variable using the fus-bdinfo structure.

The non-fus images are missing the necessary scripts to get the login-tty from bdinfo, so the spawning of the login console fails.

Because of this, we had to remove the core-image-minimal binaries from this release.

You can build a working non-fus image by adding the recipe "fs-startscript" to your build.

Run the following command in your build directory (e.g. build-fsimx6-fus-imx-wayland):

Alternatively, you can apply the patch, appended to this post, so the fus-startscript will get added to any new build you configure.

Copy the patch to your yocto-fus root directory (where the fus-setup-release script is located) and run the following command there:

Please excuse the inconvenience
