thanks guys , it part of the project i need to do , just not had time to to do it , examples are good ,like to buy the finished code , just to save time to do this but in the end i am sure ill have to write it

like most projects using flash i need to have hex just for the programming of the flash chip , simply cos the code that generates the data for the flash is too big to fit into the cpu as well as the main running code
then the actual code.

i am also looking at spiting up functions over 2 cpus for other reasons , so making the updates a bit more interesting
