Linux/AMIC110: AMIC110 Linux/u-Boot boot not booting from SPI

Part Number: AMIC110

Tool/software: Linux

Hey everyone,

i'm currently working on a custom board based on the amic110 soc using u-boot and linux as bootloader and OS.

I'm able to boot u-boot and Linux from SD-Card aswell as from UART, but not from SPI flash.

I can write the files, and when i'm trying to read them they are bitwise identical.

The SPI Flash is identified correctly, and everything except the bootprocess is working fine

U-Boot SPL shows only the following Message:

SPL: Unsupported Boot Device!
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

I've already tried several versions of u-boot, including old ones from TI that contain the am335x_evm_spiboot_defconfig, but no success whatsoever.

Any ideas?

Thanks in advance,

Dave
