Hi JR,

Can you first de-solder the chip and then check for the short on the board?

Gautam

This chip was working while loading programming and when we started for testing the PCB we noticed that DSP failed(short)

Hello,

It sounds like the device was damaged at some point during your testing. It would be good if you could remove the device and test the nodes on the PCB to see if the shorts are on the PCB or limited to the device. Do you have the ability to remove the device from the board?

Best Regards,
Adam Dunhoft
