Dear Friends

I should write an hex file in an external memory.
For do it I should simply read byte to byte from hex file and write in a memory or there are header in hex file that I must skip?

Thanks

It depends whether you need the hex file itself in memory, or just the data content. An Intel Hex file contains ascii characters representing a start character, header, address, data and a checksum on each line. To store just the data, you have to strip out all other stuff, and translate the characters representing the data into bytes, then store them at the correct addresses.

Google for the Intel Hex file structure.
