 Using First Touch board with 5V on Vddio0 and Vddio2, ports seem to suddenly break or get stuck high. Happens after hours of running fine, happened to two boards. On first board both Vddio0 and 2 related ports was stuck, second board only Vddio2 ports stuck so far. Core and 3V ports running fine. Anyone seen this? Anything I can do to "heal" the boards? Quick reply much appreciated!

   

Thanks, T

 Correction - they are stuck LOW, and this is also what I see when I read the port after writing high to it.

Hi Torpe,

   

 

   

Can you please throw more light on the voltage setting with respect to the statement "Core and 3V ports running fine"?

   

Is the drive mode of the port pins in the project set right?

   

It will be helpful if you could attach the project so that we can try it on our test set-up.

   

 

   

Regards
