Programming the Coldfire V2 Flash module
Posted by alessandro.strazzero@gmail.com on May 9th, 2008


Hi all,

I have to program the MCF5282 internal flash module. After the setting
of the CBEIF
bit which starts the programming I get an access error exception. The
user's manual
tells this exception occurs because the flash is write-protected. The
WP bit inside the
FLASHBAR register is the flash write protection bit, but it can't be
cleared also if my
software runs in supervisor mode. I also be sure the CFM field
contents remove any
kind of protection to the flash module.

Any kind of help will bre appreciated.

Best Regards

/Alessandro
