Should the RK3399Pro work out of the box on OpenBSD? Has 8GB RAM

[Joseph Mayer]

Hi arm@!

Should the RK3399Pro work out of the box? Its specs look equivalent
with the RK3399's but it has 8GB RAM.

If a hardware donation is of use let me know.

RK3399Pro is the successor of the RK3399, essentially the same but
supports 8GB RAM and bundles some NPU which OpenBSD of course not will
support. There appears to have been some delays from Rockchip's side in
manufacturing, as Pine64 said they delayed making their own SBC for
this reason, ref. https://www.pine64.org/2019/08/05/august-update-london-meetup-pinetab-news-soedge-and-more/.

Together with the Broadcom BCM2711 based Raspberry Pi 4 Compute Module
[2] this is the only very low cost ARM64 with 8GB RAM I'm aware of.
This said Raspberry is already supported by OpenBSD. RK3399Pro has
the benefit of having four lane PCIe (versus one lane) (and having
USB 3), which makes it way superior for real world IO. Quickly
comparing Geekbench results, RK3399Pro looks about 20% faster than
BCM2711. BCM2711 is uniquely manufactured for Raspberry (sigh), so
there will be no SBCs in the wild with it from other manufacturers.

Thanks,
Joseph

Yes it does. See my 'Radxa ROCK Pi N10 Works' email.

I was excited about this board too but note that only
4GB of the ram is available to the CPU. The other 4GB
is reserved for the NPU.
