I am using mot V1.2 codewarrior with the icd12 P&E BDM and dp512.
In my project I write and read amount of data from ppage $28 of the flash. these operation are done well. when I reprogram from the codewarrior IDE this page is overwritten with zeros (not 0xff) and the data is lost.
I tried to check if it has somthing to do with the preload.cmd file where I erase the page modules but it seems not.
1. can it be that the program itself ovrewrites this page?
2. is it possible to burn just the program data without burning the other pages? where can I find some more information how this proccess is done?
any idea why?
