I am looking for a bootloader for my mega16 uC. Till now I have come across 3 bootloaders for the same:

Megaload http://www.microsyl.com/megaload/megaload.html
STK500-Emulating Bootloader http://hubbard.engr.scu.edu/embedded/avr/bootloader/
AVRBL http://www.prllc.com/productcart/pc/viewPrd.asp?idcategory=10&idproduct=27

The latest version of Megaload gives compilation errors which I'm unable to correct.
!ERROR file 'main.o': undefined symbol '_read_program_memory'
!ERROR file 'main.o': undefined symbol '_write_page'
!ERROR file 'main.o': undefined symbol '_write_lock_bits'
!ERROR file 'main.o': undefined symbol '_fill_temp_buffer'
!ERROR file 'main.o': undefined symbol '_enableRWW'
Done: there are error(s). Exit code: 1

The STK 500 emulating bootloader is very buggy.

AVRBL is not free and no demo version is available.

Does anyone know a good bootloader for mega16 or better still, the entire AVR family.

Yeah, I am now using an older version of megaload V 2.3. It has boot loaders for mega 8,16,32 and some more bundled with it in .hex format eliminating the need to compile.

Thanks,
let me try it out.
At least there is somebody to ask if I don't succeed.

Hello Admin,
Requesting once again for the link to the topic you were suggesting.
