BPI Team. Make Kernel 6 support on BPI-W2. Please

Banana Pi Router design BPI-W2(RTD1296)
1

Just take latest Kernel (now it 6.6.7) and make BASE SUPPORT on BPI-W2 (SATA, ETH, eMMC, SD). Perhaps rtd1296 is already in kernel support, as I have seen some pieces of code with this name. This will help many people, because this thing can’t even run docker, which requires some functions of new kernels. If you assemble the latest core for this device, you may even increase its sales, as it is perfect for (almost) any tasks that require full-fledged SATA. I looked at a large number of single boards, but this one was the one that satisfied me with the connectors. Thanks in advance, I hope you can.

P.S.: I tried to build a clean kernel, but I couldn’t run it or build uImage. sinovoip, I will be glad for your support, like many other users.

This is what I get in the UART when I try to build my version of kernel 6. There is nothing further.

This is just not that cheap and simple and is impossible to cover with hw sales margins.

Hardware manufacturers does not do Linux (they get it from SoC maker and apply small modifications to fit their case). They do not port Linux to mainline kernel as this game is in another league and it is impossible to cover those expense. Not to mention maintaining. This is done by community projects such as Armbian (there you could find such activity in forums and pull requests), OpenWRT, LibreElec … and/or professionals such as Collabora, Bootlin, … which will follow your wish upon payment for their living costs.

I think W2 Image Map - Banana Pi Wiki might be terribly outdated.

GitHub - jjm2473/rtd1295-next: [WIP]Linux kernel 5.9.0 for rtd129x, with eMMC supported has some work on 5.9 kernel.

I’ll try again build kernel 6 for bpi-w2. Maybe it will success.
