xCORE-200USB Audio 2.0 Reference Software TDM NOT WORKING

Postby sunny123456 » Thu Oct 19, 2017 2:58 am

hi all ,
I use reference software (ie sw_usb_audio-[sw]_6.15.2rc1 ) for a multi-channel TDM8 application.But I chose the compile configuration such as 2i10o10xxxxxTDM8,all the tdm8 configurations seem not work, it compile fine, when I try to debug and test under windows 7 64 bit and TUSBAudio EVAL driver with xCore-200 mc audio board, it fails to play back and record audio.

could you give a bit more info about "it fails to play back and record audio." as it is difficult to diagnose otherwise. It's known working configuration (I tried this last week and it worked) so we need to find the source of the error that has been introduced.

Useful questions... does it enumerate as a USB device? Can you see the device in the control panels (windows and thesycon)?

Does 2i10o10xxxxxx work OK ? (This is not TDM but I2S instead)

Can you see frame clock and serial clock on the LRCLK and BCLK header pins?

When you xrun (or run from xtimecomposer) with IO do you see an exception?
