STM32mp157fad: system startup is stuck in the kernel stage

GongMinghe · ‎2026-04-28

Hello teachers, I am a developer of the STM32MP157F chip and would like to ask you a question about device tree configuration. Please help me.

The version I am currently using is as follows:

optee 4.10

uboot 2023.10

linux 6.6

At present, the system startup is stuck in the kernel stage. I have attached the device tree and system startup log. Can you help me analyze the specific reasons? Thank you very much.

I've been stuck on this problem for many days。

Hi @GongMinghe

I'm not expert in DTS, I will try to give you some help.

From your log, seems you are running custom HW.

Is your HW fully working ?

Is the crash occur always at same position ?

Did you adapt you DTS to your HW ?

Did you checked the correct DDR fddrbehavior (https://wiki.st.com/stm32mpu/wiki/STM32DDRFW-UTIL) ?

Strange lines in your log, should be different than 0

- PER : 0 MHz

and also a huge time 'hole' of 10 seconds, so maybe issue is around those lines.

[    2.199619] Run /init as init process
[   12.735316] platform 50000000.rcc: deferred probe pending

May I propose that you carefully compare your DTS VS the DTS of the EV1 starter package and check if every HW difference between EV1 board and your custom board is correctly reflected, especially on power and clocks (e.g. HSE bypass or crystal mode, etc...), as well as external peripherals differences.

Regards.

Tip of the day: Try Sidekick STM32 AI agent, see here

Thanks for your reply.

You mentioned PER: 0 MHz.

I have successfully modified it to PER: 24 MHz before, but the system still failed to boot. I believe the core issue lies in this log:

scmi-clocks: probe of scmi_dev.2 failed with error -1050650364

This log entry was added by myself for troubleshooting purposes.

It seems the problem is mainly caused by incorrect clock configuration.

I have tried using the clock settings from the EV1 reference template, as well as clock configurations generated by STM32CubeMX, but neither solution allows the board to boot normally.

I will continue troubleshooting this issue after the holiday. Regardless of the outcome, thank you very much for your support and reply. Wish you all the best with your work.

Here are the three failed points shown after system boot. I would like to confirm with you: For the 6.2.0 SDK version, is the information about restricting kernel access to I2C4 correct?
