U-boot failed during SD access

[Gsard.2253]

Hello Community

I'm trying to bring up a new architecture board based over STM32MP151aaa core.

From what I see from the serial the u-boot prompts leaving the following trace:

Boot over mmc0!

Saving Environment to EXT4... Failed (1)

Now for the moment I ignore the ETH error and I focused on error on EXT4.

I expect that boot it' s ready to load kernel from SD to ram and start with it.

What's going wrong?

Thank' you in advance.

I agree that ETH message has to be ignored.

Please check the partition setup in CubeProgrammer .tsv file

I recommend that you compare the Device Tree your defined with the one used on a working board (e.g. Discovery DK2)

The following items in your log are suspects (but might be ok)

- PER : 0 MHz (it is "24 MHz" on DK2 log)

- MMC:  STM32 SDMMC2: 0 (it is "MMC:  STM32 SDMMC2: 0, STM32 SDMMC2: 1" on DK2 log)

Thank you Patrick for your prompt response.

In effect we have already done this kind of comparing with the 157A-EV1 that seems to be the closer architecture.

Yes anyway I'll go to check the PER: clock that 's is suspect.

What we have noticed that:

"Loading Environment from EXT4 ..."

Doesn't appears in a LOG captured from a DK2 demo board.

What does it means?

Because It seems that Loading succeed while saving not.

Or Failed (1) is related to Boot over mmc0!.

Bye
