U-Boot doesn't find SDMMC1 (mmc0)

Hi,

I have a problem while trying to bring up my board, which is based on the STM32MP157A-EV1.

What I'm doing is trying to flash the board with the same method as in the Starter Package, so I created a copy of the appropriate *.tfv file changing the name of the *.stm32 files it points to to the one I compiled after getting the proper device tree files from CubeMX.

I've come to a point where TF-A seems to load correctly, then it proceeds with the U-Boot and everything stops when it doesn't find the mmc0 (SD card if I'm not wrong).

The thing is, all the SDMMC1 signals are connected just as it is on the EV1, except for "uSD_DETECT".  On our design, the "uSD_DETECT" line is located on PG12 (Ball J4) instead of PG1 (Y4), which is where it is on the EV1.

I've been trying to figure out how to change that on the device tree but so far I haven't learned how to do that, however, I tried checking the line that's connected to PG1 (Y4) on our design (we can still have access to it) and I see that it is not pulled up (it should have an active internal pull-up). However I tried pulling it down and up externally and nothing happens.

Is there a chance there any sort of incompatibility with some uSD cards? I tried with two 16Gb cards, one from Samsung and another from Toshiba.

Greetings,

J.

This is what I get on the serial port:

Hi @j_gil​ 

There is not known µSCard incompatibility.

Your trace looks like the one you can get while in USB / DFU boot mode to flash ...

Can you check your boot switch configuration ?

Guess you are attempting nor + SD boot mode using FlashLayout_nor-sdcard_stm32mp157c-ev1-trusted as template ?

Which partition did you modified with your new TF-A and U-boot ? The 2 first -boot ones or 0x4 to 0x6 ?

Thanks

Olivier

Hi Olivier,

Yes, I was trying to flash, so I had the Boot switch configuration as in USB/DFU mode. I have tried in SD-Card mode but it won't go as far (please find log at bottom of message).

I used FlashLayout_sdcard_stm32mp157c-ev1-trusted as a template, but I didn't modify the partitions (should I?), what I did is change the names of the *.stm32 files it points to the ones I compiled.

Should I use the nor-sdcard as a template?

Kind regards,

J.

Hi @j_gil​ 

Ok so you want to boot from SDCard.

Could you please share the .tsv file you are using ? ( in public or MP as you wish )

Thx

Olivier

​Thanks,

This looks correct.

So now, please share TF-A and U-boot dts file.

Hi @j_gil​ 

The last boot log you sent still contain DFU trace which does not match with a boot from SDCard. Please check and clarify boot switch configuration.
