I am trying to use the EVAL-ADAU1761 with the Raspberry Pi compute module. Made my own card driver for the Pi to use the codec. I've got everything up and running(Alsamixer controls and aux bypass works) but the driver refuses to load the firmware.


The firmware and xml files are attached, used the sigmadsp_fwgen python script to generate the firmware.


Running 3.16.3 from

I'm at a loss, I have a feeling that the script is broken because the first action is unmistakably broken with a length of a full uint.
