We have a similar problem on the armstone MX8MP

Shutdown on MX8MP

Maybe it is related

Hi,

I have another question regarding the MX8MP device.
After testing shutdown/poweroff commands with the supplied image with all possible additional parameters it was found that our device always reboots.
In the hardware documentation I was not able to locate any kind of GPIO that could be set to a different level to prevent this behaviour, apparently this is required.
Could you please point me in the correct direction to implement a shutdown procedure that leaves the device in poweroff state until reboot is requested by hardware reset button or powercycle?

Thank you once again

Can't directly help you with your issue but shouldn't the fw_env contain two different copies of the fw_env in two paritions?
typically boot0 and boot1

The issue has been solved
It was missing as "HOSTTOOLS" in our distro, which is now resolved
Thank you for pointing me in the right direction

Hello,

thank you for your help.

I have added the check for crc32 to my bbappend and installed the, so far missing, crc32 binary.
However I still have a mismatch and byte-shift in the very first bytes
It looks like some escape chars are placed instead of 4 bytes, does this point to the 4 bytes of a crc32 problem?
The rest other than the marked part is 100% identical to the binary you provide

I am now building it in your Fedore dev machine and will report back

Hi,

I have a problem with installing the uboot that I compile during the image build proccess.

For some reason it will not be detected as a valid uboot image.

It shows some differences in the first few bytes when comparing to what FS provides, so maybe the compiling proccess is not running correctly? The machine I am using is Ubuntu 22.04 based, can this be part of the problem.

The file is attached

Thank you for your help

Hi,

I am trying to create a custom .wic file for the armstoneMX8MP.
I am basing this on meta-fus/wic/fus-uboot-bootpart.wks.in, but it uses the UBOOT_WIC_BINARY and UBOOT_OFFSET.

Those values are not defined in the meta-fus/conf/machine/fsimx8mp.conf, only for other machines.
Am I using the wrong wic to base this off or were they forgotten in the machine conf?

Thank you for your help
