Dear Justin,

Thank you very much for the reply.

We have received a PCM5142EVM-U REV B board We are trying to connect to the EVM using Purepath studio
via USB. I have selected PCM5120_USB_ROM.pfw

The jumper selections is as below

W1 Shunt pins 2-3
W2 Shunt pins 2-3

When I select build->run Iam getting the below error.

Connecting to the EVM.
Found board type: FWIDPCM5101EVM-S.
Board sampling rate: 48000Hz.

Application run failed. Error: Unable to connect to hardware

Can you please help


  • Hi Prakash,

    The PCM5142 also has a plugin for the PurePath Console GUI. This GUI will tell you if it can connect as well, and also the correct jumper setting for each mode. Does the D1 LED light up when you plug in the USB cable? If it does then the next thing I would check is that I2C is being sent to the part, check the TP3 and TP4 test points for I2C communication when the GUI is trying to communicate. If you don't see I2C communication, check that the jumpers are installed, and that you have an "Audio-EVM" show up in your device manager.

    If all else fails, try this:
