microphone array board which version is 1.4 cannot work

Post by shanghaiwangyong »

Hello,

we buy a microphone array board which version is 1.4 ,we find that the VBUS voltage is not connect to the XCMOS chip VBUS pin. we use the latest version software(sw_usb_audio-[sw]_6.15.2rc1.zip) ,bulid it,burn it into our the microphone array board, we find the USB is not work, when we tie a wire from the VBUS pin to the 5V, the USB function is work.so we doubt that the softare is too old for the 1V4 version board. Can you tell me how to solve this problem?

Apologies for the delay in replying. We have published a design advisory on this issue here:

It's a workaround for now rather than a solution, but it will help to get you working with the array mic board without having to make physical mods.

I hope this helps!
