Hallo,
ich habe folgendes Problem.
Ich möchte mit OpenOCD einen AT91SAM7S64 programmieren.
Da aber davor SAM-BA auf dem uC drauf war, ist ein Lock-Bit gesetzt.
Deswegen habe ich versucht, dieses Bit zu löschen. Mit diesem .cfg-File
habe ich versucht den Befehl flash protect 0 0 15 off auszuführen. Dabei
kam aber die Meldung, dass er protect nicht kennt. Was mache ich da
falsch.

Kann mir da jemand helfen?
