The bootloaders must be separated for AVRs with and without a bootloader block
This works for those with a bootloader block. The bootloader is entered and
jumps to 0x0000 if the test pin is inactive.
Modify the ATMega168 example to work with the associated bootloader.
Only works for -O1, not even -O0.
Minor adjustments to documentation and movement of common files.
Attempt to produce bootloader that is compiled with an application.
Place bootloader in high memory and call from the application start.
This is not yet working.
