ASUS IoT will provide Debian 11 and Android 12 images for the Tinker Board 3, as well as support for the Yocto Project, but again the documentation is not available at this stage. The Rockchip RK3568 SBC should not provide any benefits in terms of CPU or GPU performance compared to the ASUS Tinker Board 2S SBC powered by the Rockchip RK3399/OP1 processor, but the new Rockchip processor offers many more interfaces many of which are exposed through the latest Tinker Board 3 board.

The Tinker Board 3 will be integrated into industrial applications such as HMI automation controllers, self-service kiosks, digital signage, and other IIoT applications. The company will also offer PP-101W-3568 and PP-156W-3568 capacitive touch panels respectively 10.1- and 15.6-inch models to help with integration into products. Additional information may be found on the product page.

Interesting to see another vendor abandonning the RPi form factor. I think that this stupid constraint which has plagued many boards for a decade by limiting their connectivity is now behind us, and vendors will start to make boards that suit their customers’ needs. That’s good.

There are many advantages to standard layouts, most deviations (this included) are too specialised to get more flexibility.

What we really need are a few carefully assessed firm factors, not hundreds of variations.

There are advantages to standard ones, yes, when they’re properly thought. Rpis cannot be placed side by side because they need connectors on two adjacent sides. You cannot even place them inside a larger enclosure for the same reason. Most standard designs (like pico-itx) use only one side so that the board can be placed inside any enclosure to form a final product.

If this is like ASUS earlier Tinker Boards expect to only ever have support for an old smelly SOC vendor kernel. The Tinker Edge R still only has support for v4.4.194 kernel and the Tinker Edge T is in even worse shape!

This is still a huge problem, and mostly originates with the SOC vendor. Unfortunately the Chinese market still doesn’t understand open source for the most part.

> the SOC vendor … the Chinese market

Ray talked about two SBC of which one is based on RK3399 (Rockchip started with a 4.4 on this SoC, then provided a 4.19 and now a 5.10 and mainline support is almost complete also in the meantime) and the other on NXP i.MX8 (not exactly Chinese and AFAIK also good to use with mainline).

It seems the board vendor simply doesn’t give a sh*t and also didn’t manage to build up a community…

I only know about RK3399Pro, kind of RK3399. but still not the same one. rockchip let it as special for AI use only, so they didn’t regular update the rootfs.

Yes, Tinker Edge R is RK3399Pro and there is currently only one RK3399Pro device supported by mainline kernel (Radxa RockPi N10). ASUS itself supplies nothing newer than the 4.4 kernel with Debian 10.

Why should the rootfs matter?

It’s about kernel support and that is there. It’s ‘just’ adopting the device-tree (using Radxa’s N10 as sceleton and by comparing the 4.4 DT files making the adjustments). Of course this is something the device vendor should provide but Asus shows pretty poor performance with ARM unlike their x86 offerings.
