Part Number: TLV320AIC3104


Dear all

      The TLV320AIC3104 of my TLV320AIC3104-EVM is bad, and I replace the TLV320AIC3104-Q1 into it, but the EVM cann't work during I set the "TLV320AIC34EVM Evaluation Tool", The D2 Led will be no light.

      Why ?

    Went,

    D2 does not reflect whether the AIC3104 is good or not.  There is a TAS1020B USB audio Processor on the USBMOD-EVM and D2 Will light if the Firmware loads and the TAS1020b is seen as an audio device by Windows.  You may need to reinstall the USBMOD-EVM firmware.   follow the directions in the document below, and find the tools and firmware files in the zip file. Follow the instructions very closely. 

    best regards,
