Hello, I am attempting to utilize a raspberry pi running ubuntu server as a part of our CI/CD & testing. I'd like to be able to use this pi to automate the process of flashing our products via SEGGER, but we've been having difficulties w/ the pi being headless. I read this forum post, and it seems there's a means to get everything set up on headless. Would you be able to provide us with this information as well? Thanks!
