RE: [avr-gcc-list] AT90CAN128 bootloader

[Trampas]

Thanks to Larry and Bruce I have the bootloader source code, however I would like to integrate it into my main application. That is rather than flashing the micro with the bootloader and then loading the application I would like to combine the bootloader with my application.  I am still trying to figure out all the magic to make this happen, specifically I figure I need to:

 

#1 Use Bootloader section for all functions that are required for bootloader. Then put the –section-start bootloader commands in the linker arguments.

 

#2 Since I will assume that the bootloader’s entry function will not use the C initialization, hence it will not be the main function I assume that I will –e linker option to set it as the entry point?

 

The main question I have is that once I do this how do I tell the linker to place the appropriate address for crt_0, or whatever the C starting function, in address 0x000 for the micro.

 

Thanks
