Recovery and reset on the same relay

[sjg20]

For tegra boards (and also Samsung) I need to a reset sequence like this:

• assert reset
• assert recovery
• de-assert reset
• de-assert recovery

For some boards I have reset and recovery on the same HIDrelay. How do I tell labgrid which is which?

My exports are:

  HIDRelay:
    ## reset
    ## usbrelay 0 2
    ##serial: 6QMBS
    index: 2
    usbrelay: True
    match:
      '@ID_PATH': 'pci-0000:00:14.0-usb-0:10.1.2'

  HIDRelay:
    ## recovery
    ## usbrelay 0 3
    ##serial: 6QMBS
    index: 3
    usbrelay: True
    match:
      '@ID_PATH': 'pci-0000:00:14.0-usb-0:10.1.2'

and I'm not sure what to put in the env:

  tk1:
    resources:
      RemotePlace:
        name: tk1

    drivers:
      AlwaysPowerDriver: {}
      SerialDriver: {}
      DigitalOutputResetDriver: {}
      DigitalOutputRecoveryDriver: {}       -- added by me, a 'RecoveryProtocol' driver
      HIDRelayDriver: {}

It seems that labgrid assumes that DigitalOutputResetDriver refers to the only digital output available. But what if there are two? I don't see how to make this connection in the various configuration files.

Any thoughts on this one?

The place only shows one relay:

Place 'tk1':
  matches:
    kea/tk1/*
  acquired: ellesmere/sglass
  acquired resources:
    kea/tk1/NetworkHIDRelay/HIDRelay
    kea/tk1/NetworkSerialPort/NetworkSerialPort
    kea/tk1/NetworkTegraUSBLoader/TegraUSBLoader
  created: 2024-05-03 12:08:38.000100
  changed: 2024-05-10 10:31:59.389736

When I try to use this place, I get:

LG_CROSSBAR=ws://kea:20408/ws labgrid-client -vv -c /vid/software/devel/ubtest/lab/env_rpi_try.cfg -V do-bootstrap 1 -V do-build 1 -V do-send 1 -p tk1 -s start -a console

labgrid.exceptions.NoDriverFoundError: no DigitalOutputProtocol driver found in Target(name='tk1', env=Environment(config_file='/vid/software/devel/ubtest/lab/env_rpi_try.cfg'), var_dict=None)

The above exception was the direct cause of the following exception:
...

So it seems to see only one of the relay channels??

I have another board which needs this (Beagleplay).

Undef 'Exporter Configuration' I can see how to create a group., but I am not sure how to apply this here:

  HIDRelay:
    ## reset
    ## usbrelay 2 6
    ## hub a 10
    ## serial: 7QMBS
    index: 6
    match:
      'ID_PATH': 'pci-0000:00:14.0-usb-0:10.4.2'

  HIDRelay:
    ## recovery (USR1)
    ## usbrelay 2 7
    ## hub a 10
    ## serial: 7QMBS
    index: 7
    match:
      'ID_PATH': 'pci-0000:00:14.0-usb-0:10.4.2'

They both have the same match string, of course...

BTW I have some ideas on how to improve the configuration, if anyone is interested.

Labgrid supports this, but you have to use the labgrid-client add-named-match for resources and than manually specify the bindings for both IODrivers. Part of it is explained in the labgrid-client man page and another part in this discussion.

I managed to get this working, with the below:

play:
  location: 'lab'
  USBSerialPort:
    ## hub
    match:
      '@ID_PATH': pci-0000:03:00.2-usb-0:2.4.3:1.0

  USBSDWireDevice:
    ## hub
    match:
      ID_SERIAL_SHORT: da69

  reset:
    ## reset
    ## usbrelay 3 5
    ## hub e 11
    ##serial: 8QMBS (hub e11)
    cls: HIDRelay
    index: 5
    match:
      ID_PATH: pci-0000:03:00.2-usb-0:3.4.3

  recovery:
    ##recovery (USR1)
    ##usbrelay 2 6
    ##hub a 10
    ##serial: 7QMBS
    cls: HIDRelay
    index: 6
    match:
      ID_PATH: pci-0000:00:14.0-usb-0:10.4.2
