Jim:

I am assuming that everything was working fine until you updated CodeWarrior? Or did something else change? Is CodeWarrior communicating with the board at all now?

Hi Jim.

I had the same issue, during the project transfer from CW 7.1 to 7.2.

The solution:

I just replaced the CW 7.1 Target Initialization and Memory Configuration files (M52259EVB_INTERNAL_FLASH.cfg & M52259EVB_INTERNAL_FLASH.mem) by the files from the CW 7.2 generated example project. After that I can erase and program the flash memory without any error.

Best regards,

Andrey Butok

Andre,

Thanks for the tip. I'll give that a try. I guess that means that when 7.2 "converts" the project it must re-write these file, incorrectly. Odd, as with CW for CF, it seems that the burning of flash was configured by the xml file (which I used from the old project).

Tom,

It seems to load ram an debug ok. It's just erasing and burning flash that is the issue.
