imx8mp based custom board fail to load kernel of android-13

[kalarav_p]

We have imx8mp based custom board we are able to load SPL > UBOOT.
In Kernel loading facing issue: reboot: Restarting system with command 'bootloader'

Here are the detailed logs of kernel:

[kalarav_p · Accepted solution]

Hi @Dhruvit , SDMA firmware is present in rootfs at /lib/firmware. 
Problem was related bootconfig, we are using a customised vendors board's u-boot so there was not bootconfig supported in u-boot. 
So, we have taken changes related bootconfig from latest u-boot. and appended to our u-boot. Now we are able to load the kenrel and getting the bootconfig also.
Please refer to this link for more details.

https://source.android.com/docs/core/architecture/bootloader/implementing-bootconfig

Thanks @_angelo_ for your response.

[kalarav_p]

Hi  @_angelo_ , We tried using the modified Kernel command line as you suggested to remove the bootconfig, but we are still facing the same issue

here we have added some more logs to identify the issue.

[ 4.692979][ T1] init: Failed to create FirstStageMount failed to read default fstab for first stage mount
[ 4.703032][ T1] init: Failed to mount required partitions early ...

may be due to missing configuraions in bootconfig we are not getting proper data, Is there any method how we can pass the bootconfig ? 

[_angelo_]

sdma firmware generally doesn't stop the boot, but i suggest to fix that, since some
driver/device may not work properly. So load the firmware.

Beside this, check your commandline passed from the bootloader, there is something that is triggering a reboot.

Try to remove bootconfig maybe

Hi @kalarav_p,

I hope you are doing well.

Please make sure that SDMA firmware is present in rootfs at /lib/firmware

The detailed solution is discussed in the thread below.
