ESP32-8048S043C not programming

Postby wolfrose » Fri May 31, 2024 8:38 pm

Hi,

I have both ESP32-3248S035C & ESP32-8048S043C.

I was able to program ESP32-3248S035C easily on

https://suchmememanyskill.github.io/CYD-Klipper/

and

https://install.openhasp.com/

but ESP32-8048S043C isn't programming.

even on arduino ide, I can't upload a simple blink code

In arduino ide I get this error:

Code: Select all

Sketch uses 248501 bytes (18%) of program storage space. Maximum is 1310720 bytes.
Global variables use 18456 bytes (5%) of dynamic memory, leaving 309224 bytes for local variables. Maximum is 327680 bytes.
esptool.py v4.5.1
Serial port COM8

A serial exception error occurred: Cannot configure port, something went wrong. Original message: PermissionError(13, 'Access is denied.', None, 5)
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

the selected serial port does not exist or your board is not connected
1) Check that you are using the correct COM port,
2) Check that the COM port isn't in use by another program.
