I designed a custom PCB that has a lot in common with the USB Audio 2.0 Ref Design. I'm trying to get the software running now but i'm facing a problem i can't figure out how to solve it :(
So first in difference to the Ref Design I'm using a 400Mhz XMOS(don't need the SPDIF Thread, so i don't need the 500MHz Controller).
When in download the firmware to the controller everything seems to work quite fine. I'm using USB Audio Class 1 at the moment so i don't need a driver for my first tests. Windows is properly installing it's drivers and i can "play" music with it.
When i start a song LEDB is switching on so the Audiostream seems to start on the Board also. But when i connect my Oszi to the I2S lines there is nothing(All low.)
I'm using different Codecs, but they are held in reset so they shouldn't interfere with it.
I'm using the newest software release of the UAC2 Project 3.3[11.2.0].
I think maybe there is something wrong with my customdefines.h maybe someone of you has a guess:
Code: Select all
CODE REMOVED
