Hello!
I am trying to use UART but cannot find the port.
I installed setserial and when i do
setserial -g /dev/ttyS[0123]
I get
/dev/ttyS0, UART: unknown, Port: 0x0000, IRQ: 0
/dev/ttyS1, UART: unknown, Port: 0x0000, IRQ: 0
/dev/ttyS2, UART: unknown, Port: 0x0000, IRQ: 0
/dev/ttyS3, UART: unknown, Port: 0x0000, IRQ: 0
We have a custom device tree and I believe that the UART is activated. Here it is and the overlay
paletto.dtso (312 Bytes)
.
