ESP32-8048S043C error programming

Other Hardware 3rd Party Boards
1

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:

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.

 does not exist or your board is not connected

Return and replace it.

That would be near impossible, I'm in the middle east and the seller probably in china. Not worth the cost of shipping it back to china.

But the board boots up and run the lvgl demo ! And the PC device manager recognize the board on the COM port.

I tried to program it through platformio.

Found the solution here:

https://github.com/espressif/esptool/issues/682

By installing old CH340 driver and connecting the board on USB 2.0 port.
