This modifies a stock debian root filesystem to be able to operate as a vision pi. It is not trying to be reproducible, but should be good enough for FRC purposes.

The default hostname and IP is pi-8971-1, 10.89.71.101. Username pi, password raspberry.

Download 2020-08-20-raspios-buster-armhf-lite.img (or any newer buster version, as a .zip file) from https://www.raspberrypi.org/downloads/raspberry-pi-os/ (or https://downloads.raspberrypi.org/raspios_lite_armhf/images/ for older images), extract (unzip) the .img file, and edit modify_rootfs.sh to point to it.

Run modify_rootfs.sh to build the filesystem (you might need to hit return in a spot or two and will need sudo privileges to mount the partition).

After confirming the target device, deploy by copying the contents of the image to the SD card.

dd if=2020-02-13-raspbian-buster-lite.img of=/dev/sdX bs=1M

Use lsblk to find the device and make absolutely sure this isn't your hard drive or something else.

From there, log in, sudo to root, and run /root/bin/change_hostname.sh to change the hostname to the actual target.

A couple additional notes on setting this up:

• You'll likely need to install (sudo apt install) the emulation packages proot and qemu-user-static (or possibly qemu-arm-static)
• If the modify_root.sh script fails, you may need to manually unmount the image (sudo umount ${IMAGE}) before running it again
