Unable to get expected report as mentioned in "Strategy Fixture Example" while using uboot strategy

[bhargavthriler]

Hi, I am new to labgrid, while following the example code mentioned in "Strategy Fixture Example" and replacing the barebox strategy with uboot strategy I'm get the following error

@pytest.fixture(scope='function')   
    def shell_command(target, strategy, capsys):
        with capsys.disabled():           
 >        strategy.transition('shell')  

Later I even tried executing the barebox example, still I faced the same issue.

target = Target(name='main', env=Environment(config_file='strategy-example.yaml'))
strategy = BareboxStrategy(target=Target(name='main', env=Environment(config_file='strategy-example.yaml')), name=None, state=<BindingState.bound: 1>, status=<Status.unknown: 0>)
capsys = <_pytest.capture.CaptureFixture object at 0x7f1033fed0f0>

    @pytest.fixture(scope='function')     
    def shell_command(target, strategy, capsys):
        with capsys.disabled():           
  >          strategy.transition('shell')  

conftest.py:27: 

Am I doing some mistake, if so please explain.

My current setup is ubuntu 16.04, target platform "imx6"

Note: I didn't find any forums to discuss some issues regarding labgrid. If there is one please mention it. Sorry if this not the right place to discuss these issues.

Here's the complete stacktrace. My target is connected to "ttyUSB0".

Pytest requires the -s option if the ManualPowerDriver is used. Please try again with the -s parameter.

Thank You. Yes it works now. Seems like Readme needs to be updated.

Yes, can you create a pull request?

@Emantor is there tutorial or guide to setup imx6 boards in labgrid and get the uart logs as well, because the documentation doesn't has much information for getting the uart logs or creating our own strategies. If there is IRC channel or mailing list that would also help. As I am stuck while making a soft reboot strategy. Thank you!

You probably want --lg-log for the pytest calls. This will enable logging of the UART outputs. As for creating your own strategies, I'd start by copying one of the example strategies and changing that. You can import other python files using the imports: list in the YAML file. i.e.

targets:
  main:
    resources:
      RawSerialPort:
        port: "/dev/ttyUSB0"
    drivers:
      SerialDriver: {}
      ShellDriver:
        prompt: 'root@\w+:[^ ]+ '
        login_prompt: ' login: '
        username: 'root'
      MyFancyStrategy: {}
imports:
  - myfancystrategy.py
