PCM5142EVM-U TAS EEPROM Update

Hi there,

I'm trying to update the EVM firmware but with no success. The steps in the user guide say to short SCL and SDA before connecting the USB plug. When I do this my Device Manager only shows an unknown Device. The user guide says I should see a device called “DFUDevice”.

When I start DFUTEST.EXE the device is not recognized.

I've tried it several times but the device will never be recognized by windows as DFUDevice. So how can I update the TAS Firmware then?
