Hi,

it seems that the GPT partitionning is not regonized in SPL in part.c;

see the trace:

    ## Unknown partition table type 0

But you have correclty activate the GPT support in SPL

 CONFIG_SPL_EFI_PARTITION=y

So I uspect read error in sdmmc driver

and no HW isue as ROM code load the SPL, but only 1 wire is used i this case

you can check the SPL device tree / try to reduce the SD card support to 1 wire and 25MHz.

And activated trace in SDMMC driver / dump the data readen (for the GPT header)

Yeah, I missed the u-boot,dm-pre-reloc in one of the pins in sdmmc1_b4_pins_a. Able to boot now.

Thanks for the response.
