Hello,

 

We are trying to erase or program hex file to attiny 1616 board using Atmel IDE, but getting error 

PDI physical timed out. (25)
UPDI pin might be configured to other functionality. Try using UPDI High Voltage Activation, configured in the tool's "Communication" property page.

 

No changes in fuse are done.

 

Same error is occurring while using MPLAB Pickit 4 programmer.

 

Please suggest any possible solution. 

 

Regards,

Akshaay

UPDI has to tri-state.

An example of that defect :
