Orange Pi Zero - UARTS

Recommended Posts

Hi,

 

I am trying to use the two UARTS on the I/O pins which are UART 1 and UART 2 mapped to PG6/PG7 and PA0/PA1 respectively.  I have had a look at the FEX file and these seem to be mapped correctly to UARTS's port 1 & 2 so I would expect these to be mapped to /dev/ttyS1 and /dev/ttyS2 but this does not seem to be the case.  If I try to connect to these UARTs using screen I simply get the message: -

root@orangepizero:~# screen /dev/ttyS1 9600

[screen is terminating]

 

I have tried searching these forums and Google but have not really found anything - any help or pointers in the right direction would be much appreciated.

Hi,

 

Thank you, yes you are right ,it was not obvious which image I should be downloading, the download page is not the friendliest I have come across.  However, with that direction I now have a working wlan, so thank you for the pointer. The Orange Pi Zero is infinitely more useful now :)
