Driver timed out on play

Postby rkn » Fri Mar 22, 2019 6:09 pm


I am having an issue with a board built around the XE216-512-TQ128.
I am running the USB Audio Multichannel software from XMOS on it (Build configuration: 2i8o8xxxxx_tdm8)
When I attach the USB connection the device is enumerated and recognized as USB Audio 2 device by macOS. I can. see the LRCK and BCLK coming from the XMOS with correct values (48kHz, 12,288MHz).
The only change I made was reconfiguring the pins. This is from my xn-File:

When I start now audio playing in Plogue Bidule I get a message box with the following error message: Driver timed out on play. I don't see any data on the TDM-Out line.
Other software does not play, too, but at least Bidule gave an error message.
It seems, that the XMOS does not start to play.
Now, interestingly, if I run the software on another board from another project but with the same XMOS schematic and almost the same PCB layout, it works.
Any idea how I can debug this? Could it be that the XE216 is damaged somehow?
