I have tried ports 3 and 4, I changed in the designer, but I get no response when I used these ports. Still just the “Failed to perform I2C transaction” error when I use port 10.

Hi All,

I am not sure whether this issue is fixed for everyone but I upgraded to the latest firmware v4.2.7.0 this week and retested with socket 10, this update has resolved the issue for me so I can now run the touchscreen on either socket.

Cheers, Swifty.

I also upgraded to 4.2.7.0 and have good touch response now.

Cheers, Jos
