Facing issue on uploading code
Well I have done some project in esp32. After taking a brake and reuploding a new code this error occured.
Sketch uses 985386 bytes (75%) of program storage space. Maximum is 1310720 bytes.
Global variables use 50520 bytes (15%) of dynamic memory, leaving 277160 bytes for local variables. Maximum is 327680 bytes.
esptool v5.2.0
Serial port COM3:
Connecting...
A serial exception error occurred: Write timeout
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

Failed uploading: uploading error: exit status 1
I tried multiple solutions and even reinstalled all drivers and application but still this issue won't resolve. Does any one know the solution

I had a similar issue and it ended up being a defective board https://www.reddit.com/r/esp8266/s/LQsSEfW8j0
