i use Real time Debugger to debug my program.
I can see in my flash part memory some "uuuuu" uninitialized octect when it is not use. But it is not possible that this octect is initialized with 0xFF per default.
In fact, i think, before write data in flash, all flash was erase (0xFF) in all octect? No?
Because, when i try to read a page of 512 bytes, sometime all bytes is not use so uninitialized. My program halted!!!!
