how to connect to xCORE-200 MC AUDIO reference board with xmos_mixer command

Post by susanyin0501 »

Dear All,

In -sw_usb_audio-[design-guide](6.15.2rc1).pdf,

Image

xfash D:\sw_usb_audio-[sw]_6.15.2rc1\sw_usb_audio\app_usb_aud_xk_216_mc\bin\2i10o10xxxxxx\app_usb_aud_xk_216_mc_2i10o10xxxxxx.xe ( default compile and mixer = 1) to xCore-200 MC AUDIO demo baord,

demo board can work well ( usb can be detected, playback audio )

but when i run "./ xmos_mixer --display -aud - channel - map 0" on MAC OS, or "xmos_mixer --display-info" on Windows 7 (32 bits OS and 64 bits OS), always display "Cannt Connect" like this

xmos_mixer tool comes from attached file (FAE provided)

you should change #define XMOS_L2_AUDIO2_PID from 0x0004 to 0x0008 in OSX/usb_mixer.cpp , because it's 0x0008 in customdefines.h of sw_usb_audio-[sw]_6.15.2rc1\sw_usb_audio\app_usb_aud_xk_216_mc, it can work well in MAC OS. i didn't try it on windows OS, i have not windows compile tools.
