I have some simple code which is runing fine through Cosmic's ZAP debugger. I believe that ZAP actually programs the onboard flash so I assumed that after it was programmed I would be able to power down, remove the BDM interface, power back up and the chip would run the code (default is single chip mode?). This doesn't seem to work. I'm probably missing something fundamental here but don't know what. would appreciate some guidance. |

The most common error is not to do COPCTL = 0x00; As when you use the BDM, the COP is automatically disabled, so when you run it without the BDM, it crashes if you had not either refreshed it properly, or provided an interrupt service routine. BTW, why are you using such an old chip? -----Original Message----- From: alienprey2000 [mailto:] Sent: 28 July 2003 19:09 To: Subject: [68HC12] Programming 68HC912B32 Flash I have some simple code which is runing fine through Cosmic's ZAP debugger.
