Title: - Jumping to Program Code from BootLoader-
Post by: Imran on March 03, 2011, 03:40:25 PM

Hello Again.

I have posted a topic here before and you guys seem to be quite helpful and friendly, so I have another problem I need help with. I have a program that is too big for the bootloader (Which can have a maximum of 512 BYTES). I read that you can have a small bootloader that can "Jump" to a bigger program, but I don't know how to do this.

I Think I would have to use the:

Code: [Select]

ORG But I am clueless. Could Someone post some example code or good tutorials please.

Any Help appreciated.

P.S I am new to assembler.

Thanks for the reply,
