Hello @all I Have a Tanix TX3 Amlogic S905X3 With 4GB RAM and 32GB ROM. It has a SP6330 Wifi / bluetooth Chip. High resolution PCB Pic: https://ibb.co/zbqW5HH I want to get the Sound and BlueTooth Working. I have used the Premade "Armbian_20.10_Arm-64_focal_current_5.9.0_desktop.img.xz" and Ethernet Works, Wifi Works (with small tweaks) This link helped me to get wifi working. Armbian Build for Nexbox A95X with AP6330. My armbian info: ``` root@tx3:~# cat /etc/armbian-release # PLEASE DO NOT EDIT THIS FILE BOARD=arm-64 BOARD_NAME="ARM-64" BOARDFAMILY=arm-64 BUILD_REPOSITORY_URL=https://github.com/150balbes/Build-Armbian.git BUILD_REPOSITORY_COMMIT=62b8c07-dirty DISTRIBUTION_CODENAME=focal DISTRIBUTION_STATUS=supported VERSION=20.10 LINUXFAMILY=arm-64 BRANCH=current ARCH=arm64 IMAGE_TYPE=user-built BOARD_TYPE=conf INITRD_ARCH=arm64 KERNEL_IMAGE_TYPE=Image ``` 1. u-boot used: u-boot-s905x2-s922 > u-boot.ext 2. dtb used: ``` root@tx3:/etc/firmware# cat /boot/extlinux/extlinux.conf LABEL Armbian LINUX /zImage INITRD /uInitrd # aml s9xxx FDT /dtb/amlogic/meson-g12a-x96-max.dtb APPEND root=LABEL=ROOTFS rootflags=data=writeback rw console=ttyAML0,115200n8 console=tty0 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0 ``` 3. To get wifi working: ``` sudo mv /lib/firmware/brcm/brcmfmac4330-sdio.txt /lib/firmware/brcm/brcmfmac4330-sdio.txt.old sudo ln -s /lib/firmware/brcm/brcmfmac-ap6330-sdio.txt /lib/firmware/brcm/brcmfmac4330-sdio.txt ``` 4. Sound is NOT working via HDMI. Steps done: ``` root@tx3:~# sound.sh G12AX96MAX root@tx3:~# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: G12AX96MAX [G12A-X96-MAX], device 0: fe.dai-link-0 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: G12AX96MAX [G12A-X96-MAX], device 1: fe.dai-link-1 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: G12AX96MAX [G12A-X96-MAX], device 2: fe.dai-link-2 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 ``` 5. Bluetooth is NOT Working.
