Larry,

I created an issue to track it: https://git.lavasoftware.org/lava/lava/issues/344 I don't know why the new char needs to be sent. Most likely there was a case like this in the past.

Guys,

We have a problem as next:

The story is we have kernel exception when device boot, then per next code:

if index == cls.TRACE or index == cls.EXCEPTION:

            res = "fail"

            if action:

                action.logger.warning(

                    "%s: %s" % (action.name,

cls.MESSAGE_CHOICES[index][2])

                )

            # TRACE may need a newline to force a prompt

            connection.sendline(connection.check_char)

It will send a “#” to device, but unfortunately, the exception time is too close the final login, then the “#” was sent to user login as next:

Imx8qxpmek login: #

Then when we send “root”, it definitely cannot login, how to resolve?

More, why lava send “#” to device when kernel have exception? _______________________________________________ Lava-users mailing list Lava-users@lists.lavasoftware.org https://lists.lavasoftware.org/mailman/listinfo/lava-users
