It shows up as "Arduino Micro (COM6) all looks good but when I try to upload it cannot force the reset, tries to upload to "Arduino Micro (COM6)" and fails (I assume because it is not entering into the bootloader). When I try to upload another sketch to this port it fails (as I would expect) because it cannot force the reset presumably because the bootloader is already active. The LED does begin to blink but in device manager it remains as "Arduino Micro bootloader (COM7)". In the process the IDE forces the reset and in device manager I can see the "Arduino Micro bootloader (COM7)" replace the micro on COM6. Then I try to upload the Arduino example Blink.ino sketch - and that works too. When I plug the micro into the computer the first time it is recognized as an "Arduino Micro (COM6)". I have been able to burn the bootloader using both an Arduino Uno and with an AVRISP mkII. I made a custom PCB ( schematic) for a smaller Arduino Pro Micro and it works - mostly. I've been struggling with this issue for a few days on and off now. ![]()
