Rock 5 ITX

It's been a while since I've posted about arm64 hardware. The last machine I spent my own money on was a SolidRun Macchiatobin, about 7 years ago. It's a small (mini-ITX) board with a 4-core arm64 SoC (4 * Cortex-A72) on it, along with things like a DIMM socket for memory, lots of networking, 3 SATA disk interfaces.

The Macchiatobin was a nice machine compared to many earlier systems, but it took quite a bit of effort to get it working to my liking. I replaced the on-board U-Boot firmware binary with an EDK2 build, and that helped. After a few iterations we got a new build including graphical output on a PCIe graphics card. Now it worked much more like a "normal" x86 computer.

I still have that machine running at home, and it's been a reasonably reliable little build machine for arm development and testing. It's starting to show its age, though - the onboard USB ports no longer work, and so it's no longer useful for doing things like installation testing. :-/

So...

I was involved in a conversation in the #debian-arm IRC channel a few weeks ago, and diederik suggested the Radxa Rock 5 ITX. It's another mini-ITX board, this time using a Rockchip RK3588 CPU. Things have moved on - the CPU is now an 8-core big.LITTLE config: 4*Cortex A76 and 4*Cortex A55. The board has NVMe on-board, 4*SATA, built-in Mali graphics from the CPU, soldered-on memory. Just about everything you need on an SBC for a small low-power desktop, a NAS or whatever. And for about half the price I paid for the Macchiatobin. I hit "buy" on one of the listed websites. :-)

A few days ago, the new board landed. I picked the version with 24GB of RAM and bought the matching heatsink and fan. I set it up in an existing case borrowed from another old machine and tried the Radxa "Debian" build. All looked OK, but I clearly wasn't going to stay with that. Onwards to running a native Debian setup!

I installed an EDK2 build from https://github.com/edk2-porting/edk2-rk3588 onto the onboard SPI flash, then rebooted with a Debian 12.7 (Bookworm) arm64 installer image on a USB stick. How much trouble could this be?

I was shocked! It Just Worked (TM)

I'm running a standard Debian arm64 system. The graphical installer ran just fine. I installed onto the NVMe, adding an Xfce desktop for some simple tests. Everything Just Worked. After many years of fighting with a range of different arm machines (from simple SBCs to desktops and servers), this was without doubt the most straightforward setup I've ever done. Wow!

It's possible to go and spend a lot of money on an Ampere machine, and I've seen them work well too. But for a hobbyist user (or even a smaller business), the Rock 5 ITX is a lovely option. Total cost to me for the board with shipping fees, import duty, etc. was just over £240. That's great value, and I can wholeheartedly recommend this board!

The two things that are missing compared to the Macchiatobin? This is soldered-on memory (but hey, 24G is plenty for me!) It also doesn't have a PCIe slot, but it has sufficient onboard network, video and storage interfaces that I think it will cover most people's needs.

Where's the catch? It seems these are very popular right now, so it can be difficult to find these machines in stock online.

FTAOD, I should also point out: I bought this machine entirely with my own money, for my own use for development and testing. I've had no contact with the Radxa or Rockchip folks at all here, I'm just so happy with this machine that I've felt the need to shout about it! :-)

Here's some pictures...
