Solution ) Why Arduino Nano NOT Uploaded (2019) | How to Upload avrdude: stk500_getsync()


Hi guys, I’m going to talk about why Arduino Nano (Chinese Version: CH340) was not eroded suddenly and how to unload in the latest version of arduino IDE Lately I installed in Arduino IDE As usual, I selected the communication port and selected Arduino Nano I tried to upload my code to the Arduino Nano but it was not working I tried all of my Arduino Nano, but they were not working neither I tried to figure out what’s going on and Finally I found something has been changed There are one more processor in the menu In order to use Chinese version Arduino, you will need to select the old Bbootloader in Tools – Processor now it is working well. As you can see The example code is working now There could be so many possible reasons you cannot upload your code. this could be one of solutions I hope it works for you Bye

  14. thank you so much!
    i was getting a splitting headache trying to figure out why it was not uploading

  15. Hello, I have a very urgent problem with my Arduino NANO, when I upload a project WITHOUT ERRORS he regrets that there are problems in uploading the sketch, and even when I put the ATMEGA328 (OLD BOOTLOADER) processor the following error appears:

    Arduino: 1.8.9 (Windows 7), board: "Arduino Nano, ATmega328P (Old Bootloader)"

    Sketch uses 1714 bytes (5%) of program storage space. The maximum is 30720 bytes.

    Global variables use 189 bytes (9%) of dynamic memory, leaving 1859 bytes for local variables. The maximum is 2048 bytes.

    avrdude: verification error, first mismatch in byte 0x0000

    0x00! = 0x0c

    avrdude: verification error; content mismatch

    avrdude: verification error; content mismatch

    This report would have more information with

    "Show detailed results during compilation"

    option enabled in File -> Preferences.

    Simply put: [b] AVRDUDE: VERIFICATION ERROR; MISMATCH CONTENT ERROR [/ b]

    And that he installed the [b] driver for generic (Chinese) Arduinos CH340 [/ b] and still nothing

    I tried everything and nothing works, nobody has wanted to help me, nor have I had the time and willingness to explain myself. Please I need help inmediately!

  16. Thank you dude, you are the best person ever. Saved a lot of my time just because of you.

  17. I have distroid 1 nano board before watching this video and now this nano board is working properly

  18. Thank you for solving my problem. I was ready to purchase another board thinking there is something wrong with this one

  19. THANK YOU VERY MUCH

    I LOVE YOU AHHHHHHHHH

    2 HOURS LOOKING FOR THIS AND YOU HAVE HELPED ME IN A SECOND, YOU ARE MY JESUS ​​CHRIST

  20. Amigo me has salvado de perder un dia por ir a devolverlo hasta la tienda donde lo compre a pedir el rembolso pensé que no funcionaba solo por esto muchas gracias.
