I think you answered the wrong person. :)
Okay, thanks for the suggestions.
I will check the sources. There was also a missing alias
in the Device-Tree source. I have added the specific alias
for the SPI bus. Now I'm getting the error code -2.
I'm new with U-Boot and the source code itself, but I
think the problem occurs still in the device tree file for
the specific board.
