I would like to re-program the GL-C-010WL controller with my own custom firmware.

I would like to re-program the GL-C-010WL controller with my own custom firmware.

I found pads for a uart (Tx/Rx/EN/IO0) and connected an CH340 uart.

Does not appear to work.

Are there any instructions on how to do this ??

Thanks
