Radxa ZERO 3E support

agorgl · June 10, 2024, 3:11pm

Radxa ZERO 3E is a small SBC device based on Rockchip RK3566 SoC with is a single Gigabit Ethernet port

Tech Specs

SoC: Rockchip RK3566
CPU: Quad‑core Arm® Cortex®‑A55 (ARMv8) 64‑bit @ 1.6GHz
GPU: Arm® Mali™‑G52‑2EE (Supports OpenGL® ES1.1 / 2.0 / 3.0 / 3.1 / 3.2 / Vulkan® 1.1, OpenCL™ 2.0)
RAM: 1GB / 2GB / 4GB / 8GB LPDDR4
Storage: 1 x Micro SD Card Slot
Ethernet: 1x Gigabit Ethernet with Power over Ethernet (PoE) support, powered by PoE with an additional PoE HAT required
USB: 1x USB 2.0 Type C OTG, 1x USB 3.0 Type C Host
Display: 1x Micro HDMI support 1080P@60fps
Connectivity: 40 x color user GPIO supporting various interface options (up to 5 x UART, 1 x SPI bus, up to 2 x I2C bus, 1 x PCM/I2S, up to 6 x PWM, up to 28 x GPIO, 2 x 5V DC power in, 2 x 3.3V power pin)
Dimensions: 72 mm × 30 mm
Price: ~20$

It seems like an ideal candidate for a DNS server or VPN gateway.

Given that some other Radxa boards with Rockchip RK3566 already have OpenWrt images in snapshot, is it possible to add support for this one too?

If you own one, you tell us.

I want to get 3-4 modules for a project, so I could help with this. I have no experience in the embedded area (at least this kind of embedded) so I would like to try and contribute with some guidance.

maurer · June 10, 2024, 4:21pm

Is it supported upstream? If you ship a board to me I can help adding support for it.

Edit. Upstream support planned for 6.11 - https://forum.radxa.com/t/radxa-zero-3-news/21183 but we can work with this.

agorgl · June 10, 2024, 5:31pm

Fantastic! (I didn't think of searching the radxa forums about this)
I'm gonna order a few pieces and when they arrive I'll write back again here for some guidance!

Hi, @maurer

This is Tom from Radxa, we are happy to ship you a board to add openWRT support for it. Please send me a PM or email tom at radxa.com .

maurer · June 11, 2024, 11:52am

sent via pm

maurer · June 20, 2024, 8:47am

this is just to let everyone know that I've received the board from @hipboi and I will start working on support for it asap

agorgl · June 20, 2024, 9:54am

Amazing! When you have some prototype ready, tell me to beta test it!

maurer · June 28, 2024, 12:32pm

some small update - one good and one bad news:
the good part is that it boots but the bad one is that the network fails using the patchset Re: [PATCH v6 0/2] arm64: dts: rockchip: Add Radxa ZERO 3W/3E - Heiko Stuebner (kernel.org)

anyone any idea?

EDIT - my tree https://github.com/maurerr/openwrt/tree/radxa-zero3e
EDIT2 - nevermind - my last commit fixed it
@agorgl here's a working build if you want to test it - https://oshi.at/tPRZ (90days link) - I will compile all kernel modules and do a proper github release next week

agorgl · June 28, 2024, 3:56pm

Can you do some network perf benchmarks (iperf3, wireguard)? I'm really curious how this little device performs on network operations

maurer · June 28, 2024, 4:00pm

Nope. Not really possible as I have the device in my home office and there I only have an underpowered ancient pc used for remote access to my cloud rig.

agorgl · June 28, 2024, 4:02pm

At least local wireguard performance? A Wireguard comparison DB

maurer · June 28, 2024, 4:14pm

Will look into it from Monday

agorgl · June 28, 2024, 4:17pm

Thank you!

maurer · July 1, 2024, 7:58am

done here A Wireguard comparison DB - Hardware Questions and Recommendations - OpenWrt Forum

EDIT:
so a "proper release" is on maurerr.github.io/radxa-zero3e with kernel modules and update to distfeeds.conf for those
for openwrt mainline we need u-boot support so I'll request some help with that.
stay tuned

EDIT2:
uboot mainline worked in Commits · Kwiboo/u-boot-rockchip (github.com)

agorgl · July 3, 2024, 8:03am

So for the radxa zero3e patch to land on openwrt mainline do we need the relevant u-boot patch to land in u-boot master too?

maurer · July 3, 2024, 8:04am

yes we need it

agorgl · July 3, 2024, 8:06am

Is this some random fork you bumped into or do you know the guy? Should we bump him and ask him to make a PR to the u-boot master (or do it ourselves)?

maurer · July 3, 2024, 8:08am

I asked the guy via email and he told me we waits for the release of uboot v2024.07 so that the merge window for new feature will start

EDIT: v2024.07 was tagged 2 days ago so the MR should be sent soon
