Cannot connect to the board after flashing the firmware when using the ESP32-CAM-MB USB Programmer #30

Closed ani-rudh closed 3 years ago

ani-rudh commented 3 years ago

I am using the ESP32-CAM-MB Micro USB Programmer – CH340G Serial Chip (OV2640 Camera) stack image I am using the precompiled firmware in this repository (Windows 10 machine) to flash the ESP32 CAM board via the MB module. The flashing succeeds but I am not able to connect to the board after that (I use VS code + Pymakr extension). I configured the Pymakr config and tried to connect to the board, but it is forever stuck at this: "Connecting to port COM3" image

Is there anything that needs to be done for this to work when using the MB programmer module? Also, is it necessary to first flash the official micropython firmware from here before flashing the firmware provided in this repository ?

I also tried uPyCraft to flash the firmware (succeeds) and connect the board (fails), but there is an error 'open serial error, please try again.'

Any help to resolve this error would be great :)

not consistent, but works sometimes when pressing the reset button.
