Board bring-up
We brought up a new IP door access expansion board and validated it. The platform runs on the new hardware.
Hardware fault
We reproduced and diagnosed a fault on the panel, and we documented the path to a fix.
Hardware description
We wrote the board's description. All later kernel and driver work depends on it.
Kernel
We added support for a newer release, so the platform sits on a current Linux baseline.
The platform
We built out the embedded Linux the panel runs on.
Production installer
We built a production image installer. Manufacturing flashes and deploys a new unit with it.
Boot variables
We implemented U-Boot fw_env support. The software reads and writes the persistent variables that track update state and boot counts.
