Hi,
how do i determine which Board-ID my chip has?
I got a bunch of picocoremx8mpr2 rev 1.00.

well what would help? except a bigger cooling surface / active cooling.
is it possible to disable the gpu/vpu on the fly, or is cpu standby an option.
We have the following problem: our processor produces a lot of heat and our hardware engineer thinks that clocking down might help,
is there any way to clock the processor down?
Any update on this?
it works with the following (dirty) method:
We are using your latest fedora build vm with Yocto fsimx8mp-Y2021.07.2 with the linux kernel linux-5.4.70-fus
Please, we need your feedback. Since the
we are working on this little part without success. We need your support. We have quite a lot of systems here waiting for this solution and we would like to buy lots more.....if we could make it run.
any other suggestions?
Still didn't manage to get this thing working...
i know that, already renamed the folder.
And i could boot perfectly fine before the Patch, this should not be the issue here.
Now the kernel is stuck..
See attached log
when i send some data, the gpiochip2 gpios switch to out, but only with the spidev driver...
When i switch back to ltc2632 they stay in
With 0x40000156 on all cs, the gpio1 15 seems to work.
i had already commented the line in the hog group so this should not be an issue.
here is the output of the dmesg command:
i noticed that the bus gets initialized twice... dont know if thats an issue.
next i entered the follwing command and noticed that the gpio3 (gpiochip2) pins hat the wrong direction mode:
Futhermore i modified the spi-imc.c driver file and printed the return value of the gpio_direction_ouput call and also the cs pin numer
see "spi_imx_setup: cs 78"
and "spi_imx_setup: dir ret: 0" for example in the dmesg log at the top.
Sadly still not working...
Already selected that module...
I hooked up an oscilloscope and Clock, MISO seem to work, CS works only If i use the first (0) CS Pin (The predefined one) when i use the other ones the Line stays High
Tried the following device tree without success...
Perhaps I'm missing a kernel module?
Hi,
We're using Yocto 5.4-zeus with Distro fus-imx-wayland
Hi,
I'm trying to get SPI_A (ecspi3) with multiple chip selects to work,
but only the predefined chip select (gpio5 25) seems to work.
Below my device tree:
I checked that no other node is using or muxing my pins
Hi,
can you say if and/or when a new Yocto for the imx8mp release is coming?
I need a newer chromium version, but the meta-browser layer doesn't provide a newer version for Yocto Zeus.
With best regards

Hi,
i got the same problem, but I'm developing using nfsboot.
What do i do?
Simply copying the file to my tftp root next to the ZImage does not solve the problem
