Hello,

Apologies for the inconvenience.

Can you confirm that both power and USB are connected to the board? The 3.3V LED should turn on. Can you confirm whether or not this is happening?

Hello,

I see. But the Blue "USB ready" LED no longer turns on? Which EVM are you using to connect with PPC3-EVM-MB? Can you share a picture of the jumper configuration?

Hello,

I see on the PPC3-EVM_MB you have IOVDD set to 3.3V. TAS2564 only accepts 1.8V for VDD and digital levels. Can you adjust this jumper to 1.8 V and let me know if that solves the connection issue?

Other than that, the jumper configuration looks okay.

Also please ensure you are connecting both the micro USB and 5 V (to J12 or J11) on the PPC3-EVM_MB.

Hello,

Okay, lets check one last thing to confirm the PPC3-EVM_MB is the issue here.

Please connect the PPC3-EVM_MB via USB to your computer and supply 5 V to J12 or J11. Then go to your computers device manager. Does the EVM show up as the image below?
