[quote="suforeman, post:6, topic:141"]
The RPi 3 CPU core was picked because it's a great 32 bit processor (and happens to also work in 64bit mode). That said, the 1GB of RAM and the rate at which the hardware is being iterated, there has not been much movement in the Linux community to put effort into an arm64 build

So I've got my pi 3 running in 64 bit mode with Gentoo. I'm slowly updating ROS ebuilds to work on arm64, but have not done them all yet or tested ROS compilation on the architecture (because I don't want to mess up my portage tree, as getting 64 bit mode was quite a hassle).
That said, I might attempt a 64 bit ROS Gentoo image, and could upload it for everyone if there is demand for it.
