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?
