CCS Bootloader - programming Bootloader AND application?
PostPosted: Thu Aug 09, 2007 2:12 am     Reply with quote
Hello Smile

I use the CCS Bootloader - which works fine.
But is there a way to modify it so that you can programm the bootloader and the programm in one step via a programmer Question
So that if I programm the Bootloader I have the application included and can then change the first programmed application via RS232 but not the bootloader.
Can I simply include my main.c into the bootloader at a location where it can get overwritten by a new programm version via RS232 or somthing like that?

This is possible. In ex_bootloader.c replace application() by an include of your main.c. You will also have to rename your main() to application(), or even better make this dependent on the _bootloader being defined.

Another option that looks promising but I haven't tried yet is to create the bootloader and your application as seperate programs (but at the correct final program addresses) and then combine these two afterwards if needed.
