[Linaro-validation] LAVA prompt and boot complete matches

Hi,

I have a board here that doesn't boot to a prompt, it boots, but you don't get a prompt until you hit enter. At that point it is the most basic sh prompt (# ). I am hoping to get the developer to get it to a prompt, but until then it would be good to work around that if I can.

I imagine LAVA uses a regexp to detect when a board has booted, but I can't find it in the source. Is it waiting for the command prompt or can I apply some expect style scripting? Do I need a prompt in a specific form for testing? I have seen LAVA with the return code of the previous command in the prompt before, but don't know if I need to get images set up to do that or if I can script setting that up as part of a test or boot process.

Thanks,
