Can anyone help me to get uart5 and uart6 running ?
I have set up script.bin for PI10, PI11, PI12 and PI13
and the system now shows them in dmesg as ttyS1 and ttyS2
I have linked U14 pin 45 and 47 (tx to rx)
and linked U14 pin 46 and 48 (tx to rx)
When I run minicom I do not get any response on either ttyS1 or ttyS2

Well I have answered my own question. Even though the two uarts which I am using
are 2 wire, the minicom application defaults to hardware flow control and as soon as I switched
that off hey presto data is delivered.
It makes no sense that a 2 wire interface should have hardware flow control
but there it is.
