9 years agoI'm (now) using a 5CEFA5F23. I found the problem in a very circuitous way, but finally let the compiler choose the device and the pinout and it compiled successfully. This led me to look at the package options and finally the document that described the various limitations. Your problem sounds different and unfortunately I can't shed any light. I learned long ago, however, to make sure the compiler is happy with the device selection and pinout before committing to a PCB.
