I don't have SSH access or a dedicated external monitor and keyboard for this raspberry pi, so I would prefer to have serial access, which I have working with a device-tree overlay. The thing is, I ALSO need a uart device to talk to an expansion board.
I just flashed the latest OS, 2017-03-02-raspbian-jessie-lite.img
, and have been reading through tutorials on getting serial access, but not necessarily serial access WITH another serial port. I don't care about bluetooth at all and only require a moderate (115200 bps
) baud rate.
How can I get serial console on /dev/ttyAMA0
and serial access to my other board on /dev/ttyS0
?
