UCD3138AFW-LLCWSRDTO: Unable to download Practice Lab Codes to UCD3138 device on a UCD3138OL64EVM-031 board

Part Number: UCD3138OL64EVM-031
Other Parts Discussed in Thread: UCD3138

Hi,

I have a UCD3138OL64EVM-031 board with me.

I am trying to download available UCD3138 practice lab firmware codes (downloaded from: https://www.ti.com/tool/UCD-TRAINING-LABS) into UCD3138 device onboard.

I am able to build the codes in code composer studio v12 and the .X0 file is also generated.

But when I try to download the .X0 file into the device using UCD3138 GUI, it gives an error as:

NO PMBUS DEVICES RESPONDED TO A DEVICE_ID REQUEST.

Please let me know how to resolve this error and download the firmware.

Regards,

Pratik.
