How can I figure out, if an Arduino UNO is defect? Have on, which I can't upload sketches to. It's not working on Windows, even on Linux.

Everytime the following warning appears:

avrdude: stk500_cmd(): programmer is out of sync
avrdude: stk500_loadaddr(): (a) protocol error, expect=0x14, resp=0x18

avrdude: stk500_paged_load(): (a) protocol error, expect=0x14, resp=0x98
avrdude: stk500_cmd(): programmer is out of sync
avr_read(): error reading address 0x0000
    read operation not supported for memory "flash"
avrdude: failed to read all of flash memory, rc=-2
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0xe6

I don't have a clue of how to fix it. The IDE's version is 1.8.8

Is the Arduino Bricked? Restarting both systems, the Arduino IDE and even Arduino (Reset) didn't help.

  • Is it genuine or a Chinese clone? – Majenko Feb 5 '19 at 20:39
  • It had worked over three years. It's the original (dark blue) Arduino UNO. – Jacky Tech Feb 5 '19 at 21:00
  • When the serial port is detected by the computer but uploading is not possible, then you can try to burn the bootloader. – Jot Feb 5 '19 at 22:35
  • What did u selected in board menu? – Pararera Feb 6 '19 at 5:23
