Partitions

Vector's partition table is pretty similar to that of an Android phone, except he has a couple extra ones added by Anki.

TODO

ABOOT

Contains ABOOT, aka. Android Bootloader. This is one of the few Android components still used in Vector.

OEM

Mounts to the /factory folder. Contains calibration logs and cloud keys which are used for mTLS.

EMR

The EMR partiton (Electronic Medical Record) contains the calibration info of the robot, its ESN, its model number, and its packout status.

boot_a and boot_b

These are the boot partitions. These partitons contain boot images. Each of these contains a kernel and a ramdisk. ABOOT loads the kernel, kernel runs init in the ramdisk, then ramdisk will load a system partition matching the slot you are using.

system_a and system_b

The partition Vector's full Linux OS exists in, corresponding to the boot slot. Slot a = system_a. Slot b = system_b.

userdata

Encrypted, mounted to /data. Used to store user information like faces, pictures, and settings.
