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.

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.

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 .


sent via pm

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


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