Its been two days I'm trying to write a Bootloader for ATXMega32E5. The Atmel studio doesn't have
boot.h header file supporting XMega.
As a result of searching and googling, I found two ASM header sp_driver.S and sp_driver.h. Even after the two readings and trial, I couldn't find how to use that asm functions in the embedded C code.
If someone came across this way, do help me in creating a bootloader. Or to create a makefile linking the source and header with the C file. That way I can call the functions and I will make my own bootloader
The functions in the assembly file are just like any C functions that get linked by AVR-GCC when you include the sp_driver.S and sp_driver.h files and call those functions from your bootloader code. For instance, put this in your main code's header file:
and then call any of the functions from sp_driver, e.g.
Make sure the sp_driver.S is included in the compile list so the compiler and linker can find it.
