This has comes up before. The first time, the chip programs fine. Every subsequent attempt runs for a while and then fails with an error message saying something like unable to send/receive. I am very new to this, and, frustratingly, everything worked ok for the previous firmware programmer. Can someone please help me troubleshoot this? I have a debug file, but I don't know how to attach it.
Many thanks.
PS Yes, I am able to read the device signature. (It says "boot loader v.3.3").
