The Makefile for this project enables you to manually flash the bootloader to your device using avrdude. All build targets will be flashed using the same target name with the _isp prefix.
You will need to specify an ISPTOOL and ISPPORT value when you invoke the command. These values should correspond to the adapter you are using on your system.
$ cd avr/bootloaders/athena/src
$ make debug328_w5500_isp ISPTOOL=stk500 ISPPORT=/dev/cu.usbserial-14110
Here are the supported build targets. Append _isp to invoke avrdude on the target.
- Standard Bootloaders
- atmega1284_w5100
- atmega1284_w5200
- atmega1284_w5500
- atmega2560_w5100
- atmega2560_w5200
- atmega2560_w5500
- atmega328_ethernet
- atmega328_w5100
- atmega328_w5200
- atmega328_w5500
- Debug bootloaders
- debug1284_w5100
- debug1284_w5200
- debug1284_w5500
- debug2560_w5100
- debug2560_w5200
- debug2560_w5500
- debug328_w5100
- debug328_w5200
- debug328_w5500
If you're not sure about the proper settings to supply, check the Arduino debug output when burning a bootloader when the IDE is properly configured for your tool. You will be able to find the ISPTOOL value by looking for the -c flag (-cstk500 below). The ISPPORT can be identified by finding the -P flag. (Note that the port will likely change every time you cycle the USB connection of the programmer. It is almost always listed as a USB serial device).
