Title: Flashing GH60 with avrdude?
Post by: Plasma_000 on Thu, 28 December 2017, 00:43:17

I just received my GH60 PCB and I want to try using avrdude to flash my hex file into my GH60.

The atmega32u4 is being discovered by USB, but there is no port to use for programming (ls /dev/cu.* doesn't give me usbmux or anything), and even when I press the button on the bottom nothing seems to happen.

Anyone know what I'm doing wrong? total noob to keebs.

You should be able to flash the GH60 (any revision including the Satan fork) with the DFU programmer.
Assuming that you're on a (Debian based) Linux machine you can install it with

Code: [Select]

apt-get install dfu-programmer
Then put the board into bootloader mode by pressing the reset button and run these commands

Code: [Select]

dfu-programmer atmega32u4 erase --force
dfu-programmer atmega32u4 flash your_firmare.hex
dfu-programmer atmega32u4 reset
Obviously replace your_firmare.hex with the actual name of your file.

DFU-programmer works fine, i'm just wondering if it can be done with avrdude instead?

Try the -c avr109 parameter.

Use 'flip1' as programmer option.

No device file for atmel dfu bootloader as far as I know, try 'usb' as port if the command requests.
