Hello all,

I want to develop a 'C' code which I would like to load as boot loader (higher address). Upon reset this code will be executed by the processor, which will sample an input pin and depending on the status of the pin either the application code or the boot loader code will be executed. I am not able to write a 'C' code (gcc) for loacting this code in boot sector. Will some please help me acieve this?

Thank you.

Did you searched on the forum? I am sure there are postings about this. Another way would be to search in the academy for bootloaders.

Thanks for the reply. Yes I did search this forum but I did not find one which answered my questions. I did not know that an academy existed on bootloaders.
