nRFgo was unable to read attach to the boards I have with the QFAABB parts, but reported QFAABA parts correctly and programmed them. nRFgo was at 1.21.02.
I updated to 1.21.1.3 and it can now attach and seems to program the QFAABB part ok, but it reports the HWID as "Unknown, hwid: 0xb8". Is this the expected behavior in this release of nRFgo?
