Preserving EEPROM data when programming flash on 9S08DZ60

djsimpson — Tue, 17 Jun 2008 21:04:28 GMT

I am using CodeWarrior V6.1 with a P&E BDM to program a 9S08DZ60, but I don't want the EEPROM erased when I update the main flash. I have ticked the "Always preserve All EEPROM data" in the Advanced Programing / Debug Options menu in the debugger, but it makes no difference.

Strangley, the data is not actually erased to 0xff, but any data which was not 0xff is programmed to 0x00.

Can someone point me to the correct way to preserve the contents of the EEPROM?

Thanks

David

Hi,

I haven't tried it personally *but* apparently you're supposed to be able to protect different areas of flash by noting it somehow in the prm file. Sorry, I don't remember much more than that.

Please post again if you get it working.
