@nick a Thanks will check it out

@John Taylor I found the driver source code for your wifi but it's for an older android/linux kernel. I asked info@lb-link.com for the linux/android driver. They sent me SWT6621S_H25.34.7.1_F25.34.6.1.rar

@emor acid The error above says you are missing node or label "reg_gmac_3v3". Add this just below "reg_vcc5v" in in your dts. https://github.com/The-going/linux-sf/blob/aa1ea7ec81c99dbc42f6d2ea4244ab4f54d0f3ee/arch/arm64/boot/dts/allwinner/sun50i-h618-bananapi-m4-berry.dts#L101-L108 reg_gmac_3v3: gmac-3v3 { compatible = "regulator-fixed"; regulator-name = "gmac-3v3"; regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; regulator-always-on; vin-supply = <&reg_vcc5v>; };

@Unrealchex try the x98h image. Or you’ll need to take the wifi node from x98h and add it to your dts.

Very weird HDMI is not functional in both armbian and multitool: they use very different kernels. Multitool uses the 4.19 vendor kernel, which should be supposed to provide "best" compatibility. The dmesg error is highly related to the missing HDMI, but in a way I can't recognize. About the VFD driver, I guess you're using OpenVFD driver. Latest kernels (both 6.12 and >= 6.16) come with tm16xx driver which is by far much much better and candidate to be upstreamed in the mainline kernel. Here is the github project reference; the driver is already compiled in the kernel, but you may need to edit a device tree overlay by yourself to let it work with your board. To try some debugging, the complete dmesg output and the original device tree of the stock android firmware would be very useful.
