Re: [avr-gcc-list] atm32u4df and avrdude
Hi Bruce, If the software is anything like the gh60 keyboard then there is a button on the board that gets you into programming mode. I'll assume you have the ELF file you want to flash, let's call it `firmware.elf'. When the board is in programming mode: 1. avr-objcopy -O ihex firmware.elf 2. sudo dfu-programmer atmega32u4 erase 3. sudo dfu-programmer atmega32u4 flash `firmware.hex' (1) converts the elf format to intel hex format. (2) erases the flash memory, you could omit this step if you want. (3) uploads the new firmware to the flash memory. Finally, you could `sudo dfu-programmer launch' to start execution, but this is equivalent to temporarily removing the power. It should be this easy because the atmega32u4 has USB built in, it just has to be in programming mode. Linux should autodetect the chip (dmesg --follow) will show you the USB bus events as they take place, among other things.

Re: [avr-gcc-list] atm32u4df and avrdude
Hello I personally prefer hardware programmer named "AVR Dragon"-> https://www.microchip.com/DevelopmentTools/ProductDetails/PartNO/ATAVRDRAGON You can communicate with mcpu using avrdude. Command line should looks like: avrdude -p m32u4 -c dragon_isp -P usb + options for selected operation. AVR Dragon is working well on Linux machine. There is no need to install drivers or configure system. Just invoke avrdude and it is working (you may need to use "sudo" if permissions for USB is restricted).

You can also use an arduino as a programmer with avrdude.

I've used the Raspberry Pi with avrdude to program AVR parts before.
