I’m rather new at Arduino, i have experimented before but i recently got my own board (Arduino Due R3). Whenever I try to upload to the board it gives me that error (title). I am using the Arduino ISE and my OS is Linux: Ubuntu. I accidentally hit the ERASE button and now the L-LED does not flash when I press reset, or do anything. I’m a little concerned that there’s no bootloader, but I think that’s the worst case scenario. Please Help!
