issue flashing firmware

[bilsch]

Hey,

not sure how to ask in a form or anything - missed it or just not a place to ask?

Whenever I try to flash the firmware I get the following error:

``` ❯ make yampad:default:avrdude QMK Firmware 0.6.396 Making yampad with keymap default and target avrdude avr-gcc (Homebrew AVR GCC 9.3.0_2) 9.3.0 Copyright (C) 2019 Free Software Foundation, Inc.

I tried copying the file from the repo and see the same result. I'm trying with these boards:

Any ideas? I have the same issue from linux, mac and windows. If I use arduino to upload blink works no problem

Hi,

I already encountered this behavior on Linux and usually this solved the issue. Does this help you?

It’s weird that with the Arduino IDE works...

Thats interesting but I have the issue from windows, linux and mac. I was able to get the firmware to apply to the usb micro variant but the usb-c one I have not gotten working.

Essentially I triggered the reset pin and extra time and that seemed to work. Feels like a timing issue in avrdude or elsewhere to me ( and/or a bug in the pro micro from sparkfun? )

Anyway I really appreciate the response and the project thanks!
