Lab 2_1B - Terminal not waiting for input

1

I finally got Lab 2_1B to run. After many attempts, I realize if I unplug/replug that thngs work a lot better.

Is this lab supposed to wait for a response on the terminal? CWLITE XMEGA

Text appears on the terminal screen but quickly loops out or something. Not sure what is wrong. Hence this post.

9600 baud

Sample output on restart -

I do not get a chance to enter anything.

No, it doesn’t really matter if you get the full message here - the target throws that stuff over serial and doesn’t care if we receive all of it or not. IIRC you can play around with the baud rate to get the full message.

The password immediately failing sounds strange. Are you using a serial console (something like PuTTY)? We’re also sending/receiving serial messages over the same interface that we use for most of the ChipWhisperer API.

Yep. Was using Putty.
