fatal error occurred: invalid head of packet (0x65): possible serial noise or corruption. esp32 cam , I GET THIS ERROR EVERYTIME I TRY TO UPLOAD CODE TO ESP32 CAM FROM MY ARDUINO UNO.
TRIED MANY FIXES LIKE INSTALLING DRIVERS AND CHECKING CONNECTIONS . PLS ANYONE HELP ME WITH THIS ASAP.
THANK YOU!
Are you holding the reset button on the esp32, if you are try uploading without holding it and if you aren't try holding it while uploading. Also try a different baud rate. Try a different usb cable and do you have anything plugged into the esp32?
yeah i tried without holding it , it shows no response recieved or something like that. I guess ur speaking abt the reset button in the esp32 cam.
tried using different cable and baud rate , still persists.
thankyou.
sorry my bad, I meant the BOOT button. Also do you have a different esp32 and/or arduino you could try?
which button r u refering to , i cant figure it out , am a beginer so i dont know much. do u mean the red button in arduino uno?
Sorry I forgot that esp32 cams do not have boot buttons. Just to confirm that your wiring looks like this:
With this pinnout:
5V to 5V on the board (or 3.3V to 3.3V).
GND to GND.
TXD orange cable to UOT on the board.
RXD yellow cable to UOR on the board.
A jumper between GPIO0 and GND (before uploading the code).
yeah the same
and iam sure that my esp 32 cam is functioning.
Pls help me with this since i have to submuit my project.
I moved your topic to a more appropriate forum category @thavanesh.
The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.
In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.
Thanks in advance for your cooperation.
The UNO needs to have its RESET pin connected to GND, otherwide the USB to serial converter on it will conflict with the connections to the ESP32CAM.
And how are you sure ?
before uploading code , when i press the reset buttom on esp 32 cam , in serial monitor it shows waiting for download.
And i guess its working
yeah did it also
