uart traffic NanoPi Neo

[Rob Tapp]

I have a NanoPi Neo.  I am trying to get a gps module setup on it.  Just at typical neo6m, serial gps module. 

I would like to start out at the basics.  I am not new to linux, or micro controllers, but I am new to the nanopi.

 

How can I confirm that something is talking on the serial ports?   Is there a way to route the serial port traffic to the terminal when I am logged in through ssh?

I am not sure the uart1 is enabled, but even if it is enabled, I really wouldnt know how to confirm it.  Does anyone know where I can look to find some info?

 

I would like to find out how to enable the serial ports for communication with another device & how to confirm that I have it enabled and confirm there is traffic coming in.

Anyone have any ideas on where to I can look to find this, or does anyone know how?

Hi,

take a look at this thread:

The user is using picocom to check the traffic on ttyS2:

picocom /dev/ttyS2 --baud 115200 --echo

Hi.  Thanks for the response.  I will check it out.   Is there any documentation on the armbianmonitor command?

To provide logs:

 

https://docs.armbian.com/User-Guide_Fine-Tuning/#how-to-provide-boot-logs-for-inspection

 

There's also "armbianmonitor -h" which shows the possible options.

Ok, I think I understand that part now.   Thanks!

Awesome!  Thank you for the help.  I was able to use the picomon to figure out that I needed to be wired to the uart0 to see the gps data coming in.
