stm32 to UART on the HAT UP4000
UP4000 with UP-APL03 R1.1 (UPAPBM11)(07/01/2022).
- Use lubuntu 18
- Bios UPAPBM11
- Installed the Upboard Kernel
- Configure support for the GPIO header (https://github.com/up-board/up-community/wiki/Ubuntu_18.04)
But I get no returned chars on tty5.
I have many Up4000 board in my lab. So I tried to install in same condition and setup. Result is another 3 upboard can get chars from UART port.
How I can solve?
