I am having the same problem: debugging P1021 with Eclipse CodeWarrior for PA Version: 10.1.1.
It does support P1024, P1025, but no P1021.
I have tried setting a project for P1024, but obviously I get a error when connecting to P1021 with USBTAP and CodeWarrior.
Does anyone know if is it possible to debug a P1021 with Eclipse CodeWarrior for PA Version: 10.1.1 and USB TAP?
