I’m trying to connect via uart H43 front phone jack. Flashing the serial firmware i cant connect serial but can connect usb. Flashing the usb firmware i can’t connect either. I haven’t ruled out that i might have an issue with my hardware configuration (will do further testing) but i do know for sure that the board schematic i have and the pin map on make menuconfig do not match.
Can confirm my hardware (le potato) can connect to other devices uart including 250000 baud rate.
