Rising edge problem when doing Tutorial #B2 lab

When I executed lab2 which is on tutorial website,I met problem that
I couldn’t capture any trace when I set rising edge trigger.
this is my setting :
and this is my board setting:

when I changed rising edge to falling edge or low or high trigger,It captured traces but
had this message:

and I have completed lab1 but the monitor didn’t print out expected text like this:


Ah - there should be a jumper near the AVR where the “TRIG” text is! That should fix the issue.

I’ll update the documentation too - the TRIG jumper is only on newer boards, the older ones didn’t have it so might have been confusing.
