xCORE-200-MC-AUDIO Question

Postby Alfred Goh » Sat Sep 02, 2017 10:32 am


I am new to this platform. Currently starting to look at xCORE-200-MC-AUDIO and development tools.

I have 2 questions:

1. Here is the issue, I downloaded and imported, sw_usb_audio_[sw]_6.15.2rc1, app_usb_aud_xk_216_mc.
The built configuration was 2i10o10xssxxx, no code was modified. When I connect to my Macbook Air and Pro, the audio plays. However, when I connect to my Window 10 Home system (after running XMOS_TUSBAudio_eval_v4.11.0_2017-05-16_setup) and directed to XMOS XK-AUDIO-216-MC-AB...the device status shows "This device cannot start (Code 10)...{Operation Failed} The requested operation was unsuccesful."...Same issue on Windows 7. What am I doing wrong?

2. 1. What is the firmware configuration that came with the xCORE-200-MC-AUDIO board? Anyway I can re-build with the same factory configuration and flash to the factory version that came with the board?

1) may be the case if the device has crashed and is no longer available to service requests from the USB host. Have you run it on the debugger to find out what happens to the target in this state? xrun --dump-state can be handy if you do't want to use xgdb. It's only a guess.. Also, try something simpler liker 2i10o10xxxxxx and see if that runs. It should all work OK but I'm wondering if enabling spdif Rx is an issue for the driver..

2) Default image is app_usb_aud_xk_216_mc_2i10o10xsxxxx.xe (so no input SPDIF). I would recommend building and running a freshly built version rather than relying on the default image on a board that may have been in stock a while
