No I'd expect you just need to make sure you read out a sufficiently large portion of the flash, and write it back to the same address in an erased device.

Hi,  Thanks for the file, I guess the full erase was the trick. The file I read the other night was the same length though and does not work. who knows. After working with Pics,Atmels and Tms430's this is a Beast, the GNU tool Chain is a Headache to. But should be fun.
