I already read the troubleshooting page twice without success, so I ask your support.
My Arduino Uno (8U2 / 0022) was working fine a few month ago. But today I'm not able to upload anything on it.
- When I hard reset it the Pin13/L blinks 3 times
- I'm able to dfu-program the 8U2 successfully with (Arduino-usbserial-uno.hex)
- When I plug it to linux or OSX, the systems detect it and display the serial number in kernel log
- Serial port appear correctly in the GUI : /dev/tty.usbmodem411 or /dev/ttyACM0
- RX/TX don't blink at all on upload
Any ideas how I can move on ? Does it mean the ATMEGA328P is burned ?
Please help :)
Below the trace when I try to upload the blink example (from OSX 10.6.8) :
