U-Boot does not start due to Hash error during USB Boot

[YInou.1]

We designed original board using STM32MP153D.

We cannot boot by U-boot.

When booting via USB, the Hash check (hash_sha256_check) of the page in the init_runtime of opte_os fails when booting U-Boot (see console log below).

The page that fails is different each time.

SD Card Boot does not fail in Hash check.

What is the cause and what can I do about it?

I/TC: Pager is enabled. Hashes: 2848 bytes

D/TC:0 0 init_runtime:467 Checking hashes of pageable area

D/TC:0 0 init_runtime:473 hash pg_idx 0 hash 0x2ffef4d8 page 0x29800000

​Thank you.​

Hi @YInou.1​ ,

could you please provide complete boot log when fail ( USB) and succeed ( SDCard)

Diffrerence between USB boot and SDcard boot may come from a different tf-a flavor ( serialboot for USB) which contains an error.

Thanks,

Olivier

Dear Olivier Gallien,

Thank you for your reply.

First, see attached file for SD card Boot logs.

Thank you,

Second, see attached file for USB Boot logs.

Hi YInou.1 (Community Member) 

It looks like your board is configured with a DDR 256MB, are you sure about all your settings in optee too to adjust the DDR size, also in TF-A fw config?

Both logs show that there is a physical memory overlap that ends up in a panic, the hash issue might be related.

Also it seems on the SDcard boot, the OPTEE DTB is not found.. When you build optee do you see any errors/warnings?

Regards,

Olivier
