Fixed esp32 problem: MD5 of file does not match data in flash!

[rabindrasharma]

Erase Flash memory:
Option 1:
python -m esptool --chip esp32 --port COM6 --baud 115200 --after hard_reset erase_flash
Option 2:
python -m esptool --port COM15 write_flash_status --non-volatile 0

having the commands pasted in the video description would have been a nice touch

Thank you for this, I had the same problem. Unfortunately neither of the lines helped but I figured out my problem. At the same time I was trying to flash over the serial port, I had my ESP-PROG hardware debugging board plugged in. When I removed the ESP-PROG, the serial flash worked. I hope others with the same problem can see this comment.

python -m esptool --port COM4 write_flash_status --non-volatile 0
Thanks you. This solved my problem, just make sure have install python and esptool and closed the arduino IDE before run the command.

ive found what was causing the MD5 error. It was the 3.3V pin in the ESP.
When loading the code on your ESP, make sure to disconect any external device/component conected in the 3.3V pin.
When something is using power from the ESP through this pin, it makes the flash memory cause error and corrupt data.

Thank you, your video saved my device ESP32Cam

[mahbubulhaque]

in my case cmd is showing
A fatal error occurred: Could not open COM3, the port doesn't exist

Though I have checked multiple time, esp was connected to com3
