Hi!

I have made a simple flash-loader for AT91SAM7S. Source code is included. I have used GCC for compilation of ARM code.

You can try it if you like...

Users manual:
Download [loader_sram/main.elf] into ARM using OCD Commander (this is compiled for AT91SAM7S128 !)

Connect ARM (USART0) to PC (COM1)

Start PC software:
example com1, 115200 baud, AT91SAM7S128, file: example.hex
sam7bl.exe -port 1 -baud 115200 -chip 128 -write c:\.....\example.hex

Please tell me how i can improve it...

Do you know if there exists any bootloader that can permanently reside in the FLASH area ? Otherwise I will have to make my own...

/Johan
