@c0rnelius I have noticed the SWT6621S wifi module SPAMS dmesg extensively. I tried to suppress this by using conf files in /etc/modprobe.d without success. Changing /debian-image-builder/patches/wireless/vs6621s/vs6621s/swt6621s_wifi/Kconfig line 109 to default SWT6621S_LOG_ERROR suppresses most of the messages after initial boot. DUMP messages are still periodically appear in dmesg though. Commenting out line 347 in /debian-image-builder/patches/wireless/vs6621s/vs6621s/swt6621s_wifi/skw_core.c silences them but this is an ugly hack?

I've ordered one of these to play around with. It will likely be v2.2 I guess. So if I understand correctly armbian images from here won't work (?) : https://armbian.com/boards/kickpik2b due to uboot being incompatible with RAM and/or DTS wrong for v2.2 hardware? So I will have to build a debian image as per @falcon33 post above?

Last photo just to the right of the rk3528 at 3 o'clock are the most likely (the two round gold pins). With power off check with a multi meter if one of them is connected to ground. Then with power applied use an oscilloscope to check if the other one has a clock signal on it. If it has these are probably the maskrom pins. Credit to @Hqnicolas

To get the ethernet working you have no option but to build an image with kernel support for mae621. See these posts :

The WiFi is easy. Just : wget https://github.com/radxa-pkg/aic8800/releases/download/4.0%2Bgit20250410.b99ca8b6-3/aic8800-firmware_4.0+git20250410.b99ca8b6-3_all.deb wget https://github.com/radxa-pkg/aic8800/releases/download/4.0%2Bgit20250410.b99ca8b6-3/aic8800-sdio-dkms_4.0+git20250410.b99ca8b6-3_all.deb dpkg -i aic8800-firmware_4.0+git20250410.b99ca8b6-3_all.deb dpkg -i aic8800-sdio-dkms_4.0+git20250410.b99ca8b6-3_all.deb You will need the Linux kernel headers installed though.

See my recent posts in the 64gb thread. You'll need to build an image with MAE0621A-02C support. The same thread will also give you some hints for to make the WiFi work with aic8800.

As the wifi device is the same please see my last post in this thread : Viz : Also to fix BT : sudo crontab -e then add the line : @reboot sudo hciattach -s 1500000 /dev/ttyS1 any 1500000 flow nosleep It could also be your dtb though. You could decompile my dtb from this thread and use the Bluetooth related section.

Scroll back and read all my posts from April 11 onwards (page 17). On Radxa's github there are Wifi/BT drivers for AIC8800. They are at version 4 now : https://github.com/radxa-pkg/aic8800/releases/tag/4.0%2Bgit20250410.b99ca8b6-3 Also to fix BT : sudo crontab -e then add the line : @reboot sudo hciattach -s 1500000 /dev/ttyS1 any 1500000 flow nosleep then reboot the H96.

@Hqnicolas thanks for your presentation. I found I made an error : mkdir -p ./build/userpatches/kernel/archive/rockchip64-6.12 should be : mkdir -p ./userpatches/kernel/archive/rockchip64-6.12 as the current directory is build at that point. For wsl installation @NicoD made a great video here :

@王类 here are instructions to build an armbian image with maxio kernel module. It applies to current LTS kernel version 6.12.58. Its mostly cut and paste and uses windows so I hope you can try this! @maka I'll keep working on your suggestions. Many thanks! my_board_df.dtb maxio_install.pdf

ok same error. The maxio module works with this snippet though : mdio { compatible = "snps,dwmac-mdio"; #address-cells = <0x01>; #size-cells = <0x00>; phandle = <0xee>; ethernet-phy@0 { compatible = "ethernet-phy-id7b74.4411", "ethernet-phy-ieee802.3-c22" reg = <0x00>; status = "okay"; phandle = <0x51>; }; };
-
OK do you mean boot with ethernet working using the maxio module then change DTB and reboot?
