Hi,
I use the customized board and the Linux version is 6.1.36-2.1.0. Then I use core-image-minimal as boot image. When the board is booting up, it cannot enter kernel and stop at this log.
SD card :
eMMC :
The attached file is the complete log of booting from eMMC.
Can anyone provide the correct boot log?
Thanks & Regards,

Hi @Harvey021 ,
Thanks for your help!
I have a question that is possible to decrease CPU frequency in u-boot? Is it possible to solve the boot problem?
Thanks & Regards,

Hi
Can't see boot problem from the CPU Freq. About decreasing Freq, you can have a try to modify "int clock_init" from clock_imx8mq.c in uboot.

Hi @Harvey021 ,
I found that it only support two grades. Can it be modified lower frequency than 800MHz?
And I have disabled almost all the device that I don't need or unusual. It stop at "waiting for root device". The roofs doesn't be mounted. I think that It doesn't seem to be related to CPU frequency. What could be the problem?
