You will need to follow directions from this page : https://docs.modalai.com/flash-system-image/#flashing-a-voxl-sdk-release
Tom suggested getting the SDK 1.1.3, so per instructions you should go to https://developer.modalai.com, log in, then click on Protected Downloads -> VOXL2 Platform Releases and download VOXL2 SDK 1.1.3 and follow the rest of instructions from "flashing voxl sdk" page
