Programing a custom ATmega32U4-AU board using Arduino Micro

[brunofornari]

Hey everyone!

I just developed my own ATmega32U4-AU board, which has an architecture similar to Arduino Micro.

The board is assembled, and I used another arduino Micro to burn the bootloader using this link:

Using an Arduino Micro as an ISP

ardler_dan: Basically - Can an Arduino Micro be used as an ISP to program an Uno R3 board? If so, how? Using Arduino as ISP (File->Examples->ArduinoISP) to Burn Bootloader (Arduino 1.6.x) ISP Arduino: These instructions should work on any Arduino compatible with a six-pin ICSP header (UNO, MEGA, Leonardo, etc) and a USB connection. Target Arduino: These instructions should work on any Arduino compatible with a six-pin ICSP header and an ATmega8, 168, 328P, or 32u4 processor. Step 1: INSTA…

My Arduino IDE recognizes the board and the COM, but when I try to upload any code, the IDE shows "uploading" forever and nothing happens.

As soon as I plug it off, this happens

I really think it's a hardware issue, but I don't know where to attack.
Here is my schematic:

Thanks!
