AM69, Cannot boot Linux FS from uboot

the problem could be here

Failed to load '/boot/dtb/ti/k3-am69-sk.dtb'
libfdt fdt_check_header(): FDT_ERR_BADMAGIC
No FDT memory address configured. Please configure
the FDT address via "fdt addr <address>" command.
Aborting! 

But the question is why it is working with image already bundled in SD card delivered by TI

Another hint is that uboot does not discover SD-card

Hi Marcin,

Could you try replacing tiboot3.bin with tiboot3-j784s4-hs-fs-evm.bin by renaming tiboot3-j784s4-hs-fs-evm.bin to tiboot3.bin?

Thank you,

Fabiana

I already did it as I mentioned here "I have HS-FS board so I placed on BOOT partition of the SD card the tiboot3-j784s4-hs-fs-evm.bin  and tiboot3.bin which is linked with hs-fs bin " so basically I;ve took  tiboot3-j784s4-hs-fs-evm.bin  copied it and renamed the copy to tiboot3.bin, both files are placed on SD card as it was on SD card delivered with board. Means it is not a solution here 

I've added `#define CONFIG_MMC_TRACE` to the top of j784s4_evm.h,

I see data which confirms information mentioned above 

Trying to boot from MMC2

It could be helpful

Hi Marcin,

Are you using SK-AM69 or AM69 EVM?

Thank you,

Fabiana
