Perhaps same bits are missing in 5b device tree? https://github.com/armbian/build/blob/main/patch/kernel/archive/rockchip64-6.12/rk3588-1020-Add-HDMI-and-VOP2-to-Rock-5A.patch If you get it working, make a patch and push it here: https://github.com/armbian/build/tree/main/patch/kernel/archive/rockchip64-6.12

Why does HDMI Audio work on Debian 12 Bookworm 6.1 version and not on Debian 12 Bookworm 6.12? I have updated to latest version and still no HDMI audio. Is there a patch or something i can do to fix this?

apt upgrade, after update armbian stops loading

Ok, try with this dts file /boot/overlay-user/bt_enable_clean.dts /dts-v1/; /plugin/; &pio { bt_en_pin: bt_en_pin { pins = "PH1"; // GPIO225 function = "gpio_out"; bias-pull-up; drive-strength = <20>; output-high; }; }; Compile it: sudo armbian-add-overlay /boot/overlay-user/bt_enable_clean.dts and enable it in /boot/armbianEnv.txt user_overlays=bt_enable_clean Then see if better on reboot.

bt_boot_fail_04.txt

Interesting, pls post the failed boot.

sudo armbian-add-overlay /boot/overlay-user/bt_enable_full.dts Compiling the overlay Error: /boot/overlay-user/bt_enable_full.dts:23.34-35 syntax error FATAL ERROR: Unable to parse input tree Error compiling the overlay Ok, I guess the problem was in "GPIO_ACTIVE_HIGH" macros. So I changed them to "1". File has compiled and I begun to test the board. Two times in row the board booted ok, but next time BT has failed.

Do you have idea with chip S928X-K in device Ugoos SK1 ? if you have Rom please share for me thank you so much

Ok, create a new dts /boot/overlay-user/bt_enable_full.dts /dts-v1/; /plugin/; &pio { bt_en_pin: bt_en_pin { pins = "PH1"; function = "gpio_out"; bias-pull-up; output-high; }; bt_wake_pin: bt_wake_pin { pins = "PH0"; function = "gpio_in"; bias-pull-up; }; }; &{/soc} { wcn_bt: wcn_bt@0 { compatible = "wcn,bt"; status = "okay"; enable-gpios = <&pio 7 1 GPIO_ACTIVE_HIGH>; // PH1 = GPIO225 wake-gpios = <&pio 7 0 GPIO_ACTIVE_HIGH>; // PH0 = GPIO224 (if connected) }; }; And compile it: sudo armbian-add-overlay /boot/overlay-user/bt_enable_full.dts Then enable it in /boot/armbianEnv.txt user_overlays=bt_enable_full See if there's an improvement on boot.

Here is the login prompt that failed: And about my SD Card, it is just a class 10 SanDisk Ultra card but does not say A1 anywhere. So next I tried the pre-built image for Cubieboard and it booted too! This is more stable than before, but as soon as I try to do downloads or file operations, I start seeing similar page state or mmc errors. I think this might be related to RAM frequencies as you mentioned. Is there a way I can change DRAM clock on a system after it boots? Adding to that, is there a way I can enable the display on this after it boots, or install drivers using an overlay? That would be great to test things out. I am trying to build again but it keeps failing at the same stage as last time, even after pulling the latest version. I think I should try either docker or a VM to build this, because it does not seem to be working on WSL. Thanks, Shivam

Thanks for your reply. You're right — the image I initially used came from the debmfc GitHub fork. I understand now that it's not officially supported by Armbian. I now tried the image from Armbian itself: Armbian 25.8.0-trunk.90 Bookworm Gnome However, I wanted to follow up on the CPU identification part, as you mentioned uncertainty about the S905M. I’ve opened up the stick and inspected the hardware. The SoC is clearly labeled as: Amlogic S905M Quad-Core Additionally: RAM: 2x Samsung K4B4G1646B (total 8GB DDR3) Storage: no internal NAND/eMMC, boots entirely from MicroSD Original SD card runs EmuELEC out-of-the-box I’ve attached pictures of the board below (top and bottom views), including close-ups of the SoC and RAM chips and screenshots of the partitions of the normal EMUELEC Emulator. I also tested your suggestion about verifying the CPU. It is definitely not an S905L or S905X2. This unit appears to be an Amlogic S905M I now tried the image from Armbian itself: Armbian 25.8.0-trunk.90 Bookworm Gnome and it still does not give any display output. I opened up the Game Stick and on the CPU iteself it says "@mlogic S905M

That was successful. Unfortunately, the fail rate not too much better than as I added new service: one boot was good, one was bad. Here is a log of the fail boot. bt_boot_fail_after_new_devicetree.txt

A little typo in the commands: patch -b sun50i-h6-orangepi-3-lts.dtso opi3lts-dtb.patch Should be: patch -b sun50i-h6-orangepi-3-lts.dts opi3lts-dtb.patch it should be .dts and not .dtso, its'n not an overlay. Sorry if that confused anyone.

Ok, replace the contents of the dts file with this: /dts-v1/; /plugin/; / { fragment@0 { target = <&pio>; __overlay__ { bt_enable_pin: bt_enable_pin { pins = "PH1"; function = "gpio_out"; bias-pull-up; output-high; }; }; }; }; And try again the steps

sudo armbian-add-overlay /boot/overlay-user/bt_enable_ph1.dts Compiling the overlay Error: /boot/overlay-user/bt_enable_ph1.dts:22.30-31 syntax error FATAL ERROR: Unable to parse input tree Error compiling the overlay Unfortunately, I didn't understand what the error is.

Can you help me install a unlocked version of android.

Ok, if you want we can try one more thing. According to AI, the correct way to always enable the bluetooth is to do it via a custom overlay, which is not done. First, remove the bt-gpio.service, it does not help: sudo sytemctl disable bt-gpio.service sudo rm /etc/systemd/system/bt-gpio.service sudo systemctl daemon-reload Then, create the custom overlay file /boot/overlay-user/bt_enable_ph1.dts with the following content: /dts-v1/; /plugin/; &pio { bt_en_pin: bt_en_pin { pins = "PH1"; function = "gpio_out"; bias-pull-up; output-high; }; }; &uart0 { pinctrl-names = "default"; pinctrl-0 = <&uart0_pins>; status = "okay"; }; &wcn_bt { compatible = "wcn,bt"; uart = <&uart0>; enable-gpios = <&pio 7 1 GPIO_ACTIVE_HIGH>; // PH1 = GPIO 225 status = "okay"; }; Then we can try to compile and install it: sudo armbian-add-overlay /boot/overlay-user/bt_enable_ph1.dts Then activate it in /boot/armbianEnv.txt, add the following line: user_overlays=bt_enable_ph1 If all works well try to reboot and see what happens.

Unable to reproduce. Probably date and time is out of sync. Edit: aha, this is / was the problem: https://github.com/armbian/build/commit/aa5526a9189097b87ada0784cff61bda85e46609 Which means next week community build will have this auto-fixed.

Surprisingly the fresh installation gives so much trouble for typical first command like apt-get update. I suppose something is missing in this download. It's first time the command apt-get update did not work out of the box.

The base device tree for the Renegade (roc-rk3328-cc) already includes a PWM2 device but armbian does not include the .dtbo to enable it. Thus, it is also unavailable through armbian-config. The Libre builds of Debian support it, but not armbian. I have copied the overlay from the Libre build of Debian for Renegade and it applies correctly on after I manually add it to the overlay directory: /boot/dtb-6.12.32-current-rockchip64/rockchip/overlay/rockchip-rk3328-pwm2.dtbo Note that as of today armbian-config is having a general issue with loading overlays via armbianEnv.txt. This can be bypassed by avoiding using armbian-config for overlays and editing armbianEnv.txt directly and adding the overlay name to the overlays= line minus the "rockchip-" prefix. FWIW - here's the overlay source: =========================== /dts-v1/; / { compatible = "libretech,roc-rk3328-cc\0rockchip,rk3328"; fragment@0 { target = <0xffffffff>; __overlay__ { status = "okay"; }; }; __fixups__ { pwm2 = "/fragment@0:target:0"; }; };

That's completely understandable. Given how long the A10 and A20 have been around, I wouldn't expect recent kernels to be thoroughly tested on them. Even from my perspective HDMI is more of a nice-to-have rather than a priority. I realize I might be an exception in this, but I prefer trying to fix issues myself rather than relying on someone else to do it. The only real barrier is my own lack of knowledge. That said, I believe I’ve firmly gotten to grips with device trees now. I acknowledge that I still have some way to go before I can confidently dig into driver development myself. I really appreciate the effort from you and others in making the build system so easy to use. Thanks to that, I’m able to apply my own fixes where needed with relatively minimal technical knowledge of the intricacies of Linux. I actually noticed the change today while browsing kernel.org. Exactly what I had in mind.

Further, I can't find any reference to an Amlogic S905M cpu. (https://en.wikipedia.org/wiki/Amlogic) In a google search, I see reports of some people saying the actual cpu is an S905L while others report having an S905X2. You might want to open up the stick to see what the actual CPU is.

That is not an Armbian build, but a third party fork of Armbian. These forums are for Armbian. You need to direct your question to the provider of the software you are testing, as we can't answer questions for third party software.
