Hello Armbian Community,

I'm representing GloriaForce, and I'd like to discuss the Amlogic S905X4 processor used in our RTX DUO Android TV Box.

The device has the following specifications:

• Processor: Amlogic S905X4

• Operating System: Android 11

• RAM: 4GB DDR3

• Storage: 64GB

• Connectivity: Dual-band Wi-Fi (2.4GHz + 5GHz)

• Ethernet: Gigabit LAN

I'm interested in learning more about Linux compatibility with the Amlogic S905X4 chipset.

I understand that this chipset is not officially supported by Armbian, but I'd appreciate insights from community members regarding its technical limitations and the challenges involved in running Linux on S905X4-based TV boxes.

Has anyone experimented with this processor or encountered specific compatibility issues?

Thanks for sharing your experience!

No. S4 (S905Y4) is the closest relative we support. There were a lot of issues to bring it up - we spent several weeks fulltime and with Librelec preliminary work, peer and agents help https://github.com/armbian/build/pull/10984 There are many common areas but there is still a lot of work to bring this SoC up.

What SC2 (S905X4) needs that the PR doesn’t have:

• meson-sc2.dtsi: SC2’s clock controller, pinctrl banks, reset and power domains differ from S4. This is the bulk of the work. devmfc’s 6.12 tree and the vendor 5.15 kernel are the places to take it from.

• Ethernet: the Gigabit MAC with an external RGMII PHY, plus the internal 10/100 PHY. S4 only covers the internal-PHY path, which is why devmfc so far has only 100 Mbit working.

• USB 3.0 / PCIe combo PHY: S4 has nothing here. The T7 USB3/PCIe patches (0073–0091) might be a useful reference, but that’s a guess until the registers are compared.

• U-Boot: S905X4 hardware is all TV boxes with locked vendor U-Boot. These may hit the same rsvmem check rejection of mainline DTBs that older VIM1S U-Boot had. That would decide whether an extlinux/edge-style boot works at all.
