Hi,
I am trying to build a RFID login device but when I uploaded the program the leonardo bricked itself. It won't respond to getting a program uploaded and it only shows up as "Arduino Leonardo Bootloader" for a few seconds and then disappears. Is there a way to fix this? I tried to reburn the bootloader with the arduino following Installing an Arduino Bootloader - SparkFun Learn but the tx led on the programmer jst blinks rapidly. Even after 5min. All help is appreciated!
Thanks,
L
What messages did you get when you used Burn Bootloader to install a fresh bootloader?
