Are my Arduino Uno broken or what?

Development Tools Uploading
1

So I used my Arduino Uno for about 1 years, and suddenly, I got this error

avrdude: verification error, first mismatch at byte 0x0000

         0x62 != 0x0c

avrdude: verification error; content mismatch

avrdude: verification error; content mismatch





This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

While my Arduino Mega 2560 and WeMos D1 R1 board working like normal

Code? I'm just uploading a simple Blink program I found on Examples>Basics
(pls don't tell me my favorite board is broken)

I've never seen that one before, but it seems like a faulty flash memory location. Such things are rare but it happens. Try uploading the empty sketch.

3

Did you check?

avrdude: verification error, first mismatch at byte 0x0000
0x62 != 0x0c
avrdude: verification error; content mismatch
avrdude: verification error; content mismatch

Same issue.

Tried without "Show verbose output during compilation" but the error is still the same

6

He's telling you to turn on verbose mode. compile it again, and check that output for more data.

Oh! I thought "upload an empty" sketch!

avrdude done.  Thank you.

This is usually caused by a corrupted boot-loader

9

Try burning a new bootloader (required another Arduino or a ISP/SPI AVR programmer)

10

It says "unable to find ATTiny device"

11

Great, first you will have to upload ArduinoISP code from example to Arduino mega
( Open File > Examples > 11.ArduinoISP > ArduinoISP.)

12

Then connect like this
Mega_______uno
Pin51---------pin11 (MOSI)
Pin50---------pin12 (MISO)
Pin52---------pin13 (SCK)
Pin10 --------Reset
5v----------5v
Gnd-------Gnd

13

Atlast connect your mega to pc and open ide.
Goto tools> select board (Arduino Uno)
Also in programmer >select Arduino ISP

Then click on burn bootloader
