Hi F&S support team,

we have ordered a evaluation kit PicoCore™MX8MM Linux (V14I). Currently the display is not running and I´m wondering why.
I missed to check the installed state when I received it, because I build a custom rootfs with Buildroot and…

Hi Saturnion ,

In general, I would recommend removing the PS (Push-Up Enable) and PE (Push/Pull Enable) flags for I2C.
Provided you have external pull-ups on the I2C lines, it should be fine to use only ODE (open-drain enable) for I2C.

The BBDSI has a CAN…

Hello everyone, I’m working with a PicoCore BBDSI rev. 1.4 module based on the i.MX8ULP M33 core and have run into an issue I hope someone can help me with.

For LPI2C1 I’ve been using two pins on J11 — SPI_B_MOSI and SPI_B_MISO (PTA4 and PTA5) —…

Hello,

The U-Boot is placed in a fixed RAW partition, so Nboot does not care about the partition table.
The fsim6ul U-Boot however needs the partition table to load Linux so you will have to make sure that GPT support is available here.

We have not tested…

Does the fsimx6ul NBoot expect a MBR partition table or is it also capable of handling GPT?

Hello,

yes, for fsimx6ul the U-boot is expected the User Partition. This has historical reasons, because early eMMC chips had smaller boot partitions, which may not be sufficient for future Bootloader sizes. It is more complicated to update the partition…

I am on the fsimx6ul-2024.03 release.
But I was using my own custom machine/wic-file without the u-boot section.

Thank you for the quick response and explanation, I will add the u-boot section!

Best regards,
Stefan

Hello,

i was just getting started with a new PicoCoreMX6ULL100 variant with eMMC storage, when I encountered a problem.
I was writing the sysimg (emmc output image from Yocto build) to the user partition of the eMMC, like this:

Hi,

yes, I use this layer. Thanks for looking it up, It seems to be okay then.
Qt Support also mentioned to me, that their meta-qt6 layer supports Kirkstone.

Case closed.
