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I think W2 Image Map - Banana Pi Wiki might be terribly outdated.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.
my log goes a bit further FATAL: Audio ROS Unexpected interrupt error!!

Have you included binary firmware files from oroginal vendor image?
Did you get somewhere? I am interested to revive this board, as it has everything I need, hw-wise.
OK, so I tried kernel 5.9-rc5 from GitHub - jjm2473/rtd1295-next: [WIP]Linux kernel 5.9.0 for rtd129x, with eMMC supported
The problem with this driver is, that while it boots and I do get to shell (EMMC works), rootfs of my choice (Ubuntu 26.04) can’t start systemd due to outdated features in this kernel. Latest systemd depends on certain features which are present as early merges, or not preset at all. Which excludes 5.9 out. Second, SD card doesn’t work at all. Tried everything I could, but it was always in conflict with sdio. Some calls to it were hardcoded.
So, that pushed me to latest 6.19-rc5 kernel. I had to remade whole toolchain (which still lacks u-boot of recent version to build), I also had to remake and rework DTB, namely rtd1296-bananapi-w2.dtb (new file) and heavy update to rtd129x.dtsi, which is really a simpleton in Vanilla kernel, compared to vendor’s 4.9.
So, kernel boots. But I am again facing SD support issue. RTL driver is not present, so I had to pick Arasan, which is compatible with this SOC. Currently looking for correct IRQs and clock names.
But - it is alive and the driver is probing!
