So im trying to compile the firmware for esp 32 (in windows), and followed the guide on github, also changing the #define to an ai thinker esp 32 cam model (even though im not sure its an original, my boards from amazon sellers look the same to me). Its one of those esp32 cam attached to a usb to serial converter board with reset button.
When i try to flash the firmware, I get an error message, and im not sure how to fix it. its probably a simple fix, but I was hoping for some advice!
com port says usb serial connection 8 in device manager so I changed the command to USB8
Thanks!
