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.

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.
