How to actually download L4T distro?

Reading the Quick Start guide, the instructions are: "Download the latest L4T release package for your developer system and the
sample file system from https://developer.nvidia.com/linux-tegra "

But if I actually go to that page (https://developer.nvidia.com/linux-tegra-r216 ), there is no such thing as a “Release Package”. There’s a “Driver package”, “Sample Root Filesystem”, and Release SHA1 hashes, but no actual distro. Where do I get it?

The quick start guide also helpfully refers to a file, Tegra124_Linux_R21.6.0_armhf.tbz2 , that is not actually available for download anywhere.

Any tips on how to get started?

SOLVED! It turns out it’s actually the “32-bit Driver package”.
