Firmware for the Sinara 8462 Fast-Servo

Building

Run nix build .#packages.armv7l-linux.fast-servo-sd-image to build the sd card image.
Run nix develop to build a dev shell to access the GUI.

Plug in your SD card to your computer and run lsblk to locate SD card
If there are any partitions on the SD card, run umount <mount point> all the related mount points.
Run sudo dd if=<path to the SD Card Image> of=/dev/<SD Card Device Name in lsblk> bs=4M status=progress oflag=sync
Eject the SD Card before removal

Make sure the onboard DIP Switch is in the following condition.
- EN: OFF
- MODE: ON
Install the SD Card, power up the board via the power jack or PoE and plug in the RJ45 Ethernet cable.
Wait for all the front panel LEDs except the termination status LEDs to turn off. It can take a minutes or two for first boot. If it does not boot up, try to flash the SD Card again.
Run ssh <fast servo ip address> -p 3030 to ssh into fast-servo and run linien-server run to start the linien server.
In the dev shell, run linien to launch the GUI. Add new device. Username is root and it does not take any password to log in. You leave the password field with any text.
Select the newly added device and click connect in the GUI to connect and start the GUI.
