- Buy an AVR programmer (quite cheap these days).
- Learn how to program using the command line with AVRdude
- Learn what the fuses are for the tiny2313.
To put in another way ... is there a way I can upload my own bootloader code, and not the Arduino bootlaoder?
However, I want to save the 1kB of the bootloader, becausemy flash memory space is just 2kB.
