Hi

I have some code that runs ok when load into RAM via the debugger but will not run when loaded into flash. I am using the GNU tool chain to compile with and OpenOCD to program the flash. I have modified my linker file so that the text section resides in flash and the other sections in RAM. When debugging from flash I can see that it is never getting to my main function. I have attached my startup.s and linker files.

What do I need to do to get my code linked from flash and running correctly?

Thanks

Vaughan

If you are able to debug the code in flash, why don't you tell us exactly where it gets stuck?

Hi

Thanks for the reply but figured out what was happening. When converting from elf to bin I forgot an option so the file being programmed was not correct, stopping the code from running.

Cheers
