DL233: AVR109 boot loader, e.g. for LINUX, MAC (ATmega8)
This boot loader can be burned on the Atmega8 via the ISP interface. So the controller is also programmable for open operating systems via AVRdude over the myUSBtoUART interface.
Boofa.asm e.g. with myAVR Workpad PLUS or
boofa.hex open with the myAVR ProgTool and burn it via ISP on the controller.
Code in cmd:
avrdude -p m8 -c avr109 -P /dev/ttyUSB… -b 115200 -U flash:w:programm.hex:i
