I can't upload sketches to My Arduino uno. It stuck in UPLOADING and get
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt <n> of 10: not in sync
error. RX TX not blinking when stuck in uploading.
I reinstall arduino IDE , Tried on another pc , tried with another cable but also get that error.
My pc detected UNO. I also run the loopback test and it passed. RX TX blink only when doing loopback test. I also burn the bootloader using another UNO. Still got same error.
I swap atmega328p with another uno and upload the sketch. It works and code uploaded. I also replace another ATMega328P and tried to upload also did'nt work. I also tried to reflash ATMega16U2 with ICSP. But cant enter to DFU mode.
I think one of components got shorted. I accidently put uno on metal sheet. How can i find the faulty components?
