Title: atmega32u4 no device present
Post by: Khuya on Sun, 19 June 2016, 05:38:09: I have been trying to flash the firmware on atmega32u4 with no success.

I ran

$ make -f makefile dfu
dfu-programmer atmega32u4 erase --force
dfu-programmer: no device present.
make: *** [../../tmk_core/rules.mk:424: dfu] Error 3

It keep saying no device present. I did enter DFU mode. Any idea what else am I missing?

What bootloader does your atmega have on it?
Caterina Bootloader, a true nightmare. Every guide I found on the internet didn't help.
I ultimately broke something and it's not recognized anymore in the device manager.

I wish you better luck.

You can have it stay there for 8 secs, just ground the rest pin twice quickly. A switch helps for this. Also, IIRC, out of the box, that bootloader uses serial communication, so you'll have to use avrdude. Try setting up the arduino environment and use this guide to test it, https://learn.sparkfun.com/tutorials/pro-micro--fio-v3-hookup-guide

I just made a bat file to program my pro micros to make it less work. Short the pins twice then run the batch file works well
