I'm a newbie to LAVA, so this may be a stupid question, but I have no idea how to fix this issue.

I am using a device for which I enabled the usage of the second serial port as described in the example beaglebone-black job with a second serial port - it seems that the configuration works fine, I was able to enable the secondary connection.

The problem is the following: the second serial port connects to a different shell, which at this moment is used for freeRTOS application, and its prompt ("SHELL>>") is different of the primary connection prompt  which is used for Linux("root@imx8mqevk").  When trying to actually run some commands on freeRTOS, I get timeout error and I have no idea how to fix it. 

I attached to this e-mail my test job definition, together with the log and the snip from my web.

Thanks in advance for your support,

Oana
