Arch linux on the radxa ROCK 3 Model A (RK3568)?

Hi All,

I’m looking to buy the ROCK 3 single board PC [1], based on the Rockchip RK3568. I would like to install Arch linux on this board, and use it to build a NAS (by using a JMB585 M.2 to sata converter, and several JMB57 SATA expanders for a maximum of 25 SATA drives)

On the platform page [2] I don’t see the ROCK 3, nor the RK3568. (only the ROCK64 is listed)

I’ve downloaded and extracted ArchLinuxARM-aarch64-latest.tar.gz as mentioned by the generic instructions [3].
In /boot/dtbs/rockchip I see the file one file for this SOC, rk3568-evb1-v10.dtb, but this file is not for the ROCK 3.

On this WIKI, there are instructions [4] to build a debian image for the ROCK 3. On this page they mention instructions resulting in a kernel, uboot and rk3568-rock-3-a.dtb Can these files be used to run the arch linux root filesystem?

Is the above procedure the correct way to install Arch linux on this board?
Has anybody already installed arch linux on the ROCK 3?
Are there reasons why using this board as the basis of a NAS is a dumb idea?

PS, I’ve also posted this question on the ArchLinuxArm forum [5]
