Just wanted to share an update. I got an SD mux card in the mail yesterday that we've been talking about for LAVA. This device can allow LAVA to work without having to use the master images we've all grown to dislike. Its also nice for personal use because you aren't swapping out SD cards all day long.
I played with the device last night and made some progress. It seems to be working just fine, there was only one hiccup trying to get right set of commands to power down my USB hub properly. I was then able to get this semi-working in our new "lava-core" branch[1].
The branch can flash an image using the mux, boot the device, install lava-test, power down, and repeat as needed. I'll be taking this to Connect with me and I'm really excited about getting some hacking time with the team to start making this work even better.
If you are interested, we'll be having a session on SD mux at Connect[2].
Thanks to Zach and David!
