Struggling with multiple serial ports

[ArmadilloChubbz]

Hi,

Just started giving labgrid a go, so please excuse my ignorance...

I'm trying to get multiple USB serial ports (a quad FTDI UART chip) to work remotely. I've tried various configurations but am just stabbing in the dark at this point.

This is my exporter file

pi-on-desk:
  console-a:
    cls: 'USBSerialPort'
    match:
      ID_PATH: platform-xhci-hcd.1-usb-0:1:1.0

  console-b:
    cls: 'USBSerialPort'
    match:
      ID_PATH: platform-xhci-hcd.1-usb-0:1:1.1

  console-c:
    cls: 'USBSerialPort'
    match:
      ID_PATH: platform-xhci-hcd.1-usb-0:1:1.2

That is exported and coordinator and client seems to work okay.

On my remote machine I want to do something like:

targets:
  main:
    resources:
      RemotePlace:
        name: !template '$LG_PLACE'

    drivers:
      - SerialDriver
        name: "console-a"

      - SerialDriver
        name: "console-b"
        
      - SerialDriver
        name: "console-c"
        
      - ShellDriver
        name: "console-a"
        prompt: ""
        login_prompt: ""
        username: ""

      - ShellDriver
        name: "console-b"
        prompt: ""
        login_prompt: ""
        username: ""

      - ShellDriver
        name: "console-c"
        prompt: ""
        login_prompt: ""
        username: ""

Any help would be appreciated, thanks

Hi @ArmadilloChubbz ,

this should work:

targets:
  main:
    resources:
      RemotePlace:
        name: !template '$LG_PLACE'

    drivers:
      - SerialDriver
        name: "console-a"
        bindings:
            port: "console-a"

      - SerialDriver
        name: "console-b"
        bindings:
            port: "console-c"
        
      - SerialDriver
        name: "console-c"
        bindings:
            port: "console-c"
        
      - ShellDriver
        name: "shell-a"
        bindings:
            console: "console-a"
        prompt: ""
        login_prompt: ""
        username: ""

      - ShellDriver
        name: "shell-b"
        bindings:
            console: "console-a"
        prompt: ""
        login_prompt: ""
        username: ""

      - ShellDriver
        name: "shell-c"
        bindings:
            console: "console-c"
        prompt: ""
        login_prompt: ""
        username: ""

You need to used named matches when configuring the place on the coordinator (e.g. console-a/-b/-c). Perhaps use more descriptive names, such as "console", "debug", "firmware", "application" or something like that.

Alternatively, if this is not for the same DUT, use different places.
