Hello, I have a custom board I created modeled after an Arduino Micro. The goal is to be able to program it with the Arduino IDE. When I plug the USB port in OS X recognizes a ATm32U4DFU board. However I don’t see a port listed for the board in the Arduino IDE.
I read the link below thinking I need to flash the board with an Arduino friendly bootloader. I flashed it using a USBtiny programmer with the Caterina-promicro16.hex per the article. This did not fix my problem of the board not showing up in the port list in the Arduino IDE. In addition, OS X no longer recognizes the board when plugged into USB. Pics attached to the post.
Does anyone know what I need to do here to get this board recognized by the Arduino IDE?
Note: I have two identical boards, one I did not flash that still is recognized when connected to USB and the one I flashed.
Thanks in advance for any help.
