Is there a difference in operations when power on and when the SD card is inserted for the first time?

[HMasu.1]

I use STM32MP151CAA3 Cortex-M4 on my custom board.

I have created Linux image running on my custom board.

​

In the case that the SD card is inserted for the first time, Linux image is running successfully.

However, in the case that I turn power off and power on with the SD card inserted, boot fails despite using the same SD card.

​

Is there a difference when power on and when the SD card is inserted for the first time, such as the files to read?

What should I investigate to solve this problem?

Hi @HMasu.1​ ,

Could you please share boot logs in case of success and failure.

@ArmandG​  will look at it.

Hi @Community member​ 

​

Thank you for your reply.

I will share boot logs.

​

-​Log_Boot_Error.txt: boot logs in case of failure

-​Log_Boot_Success.txt: boot logs in case of success

-​Log_Reboot_Error.txt: logs when I execute reboot command (reboot failed)

Best Regards,
