QMK atmega32u4 problem
« on: Tue, 28 May 2019, 12:19:38 »
Hey there guys, I'm having a bit of an issue flashing the Atmega32u4 (micro usb version). I'm placing my microcontroller in bootloader mode by shorting RST to GND and then plugging in the usb cable, shortly after I remove the short. I have tried doing it super fast and wait a second aswell. In QMK toolbox I never get the message that says " Caterina device connected". After I go into bootloader it says nothing, and after 8 seconds it says the Caterina device is disconnected. To me it seems that it was in the bootloader mode for those 8 seconds, but I've tried flashing it under that time with no success, also tried with the autoflash option.

Any ideas here? For the record I have 2 atmegas, so the possibility that it's broken is pretty low.

Update:
So I was a little bit hasty with posting this, after switching to another USB port it worked just fine. Should have tried that before posting ...
