Arduino stuck in dfu mode Answered
Hello, I recently updated the firmware on my areduino uno. It is this model, "
Product ID: 0x2ff7
Vendor ID: 0x03eb (Atmel Corporation)
Speed: Up to 12 Mb/sec
Location ID: 0xfd140000 / 4
Current Available (mA): 500
Current Required (mA): 100
Extra Operating Current (mA): 0
I put the arduino in dfu mode, then upgraded it with the firmware in the package contents of the arduino app of a mac. I typed in dfu-programmer AT90USB82 erase and it worked well, Then dfu-programmer AT90USB82 flash /Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/firmwares/atmegaxxu2/UNO-dfu_and_usbserial_combined.hex.
That also worked, then finally dfu-programmer AT90USB82 reset. It worked fine last night and this morning, but I found it would not take the code meant for a Leonardo board. I put my board in dfu mode again, then when I went to push the firmware again it would not take it saying it was already installed. I did use the erase command first though. Now my arduino is stuck in dfu mode. Will it just reset itself after a while? I have left it unplugged for an hour and the sketch book still won't show it's port.
