<p>
	The way the netplan + networkd integration is designed requires all the network devices (wlan0 in particular) to exist at /sbin/init time - otherwise, the netplan generator disables `systemd-networkd-wait-online.service` which also causes `network-online.target` to be reached early. In particular, this breaks any network FS mounts on boot.

	Of note, I tried logging in to file the bug via the dev contribution platform, but it looks I'm blocked from JIRA access, so am filing it here instead.

	Looks like there is an issue with the v4l device provided by the <strong>meson_vdec</strong> kernel module. Removing the meson_vdec kernel module indeed eliminates problem. Videos are played without error message using software decoding. The frame rate is unfortunately low. Otherwise I would not care about hardware decoding.

<p>
	Interestingly, the <strong>v4l2-compliance</strong> command suggests that the v4l device for the <abbr title="Video processing unit (encoding/decoding)"><abbr title="Video processing unit (encoding/decoding)">VPU</abbr></abbr> is in good shape:

I want to make fresh install and cleaned <abbr title="embedded MultiMediaCard"><abbr title="embedded MultiMediaCard">emmc</abbr></abbr> completely.

Boot process stops at line 215 and If I give "boot" command, It starts booting from <abbr title="embedded MultiMediaCard"><abbr title="embedded MultiMediaCard">emmc</abbr></abbr> with same warnings. I'm attaching full log. By the way, I tried updating bootloader by using armbian-config utility but nothing changed.

	<span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span>Hey all,<br />
	<br />
	I'm unable to boot Armbian from the SD card of my Radxa Zero 1 GB. When I download one of the official Armbian Radxa Zero images I always get the message "ALERT! UUID=eba52b2e-b77a-47b9-9619-ebda85946883<br />
	 does not exists. Dropping to a shell!"<br />
	Previously I ask the Radxa community on Discord, were I received the suggestion that the CMA memory maybe was configured too high. I tried to make an image from master (4b21499534, after <a href="https://github.com/armbian/build/pull/4151" rel="external nofollow">https://github.com/armbian/build/pull/4151</a> was merged) but that didn't help.<br />
	<br />
	When I run `dmesg` I get the following repeating error "mmc1: error -84 whilst initialising SD card"<br />
	When I run `blkid` I do not get any output<br />
	But when I insert the SD card in my laptop and run `blkid` I get: "/dev/sda1: LABEL="armbian_root" UUID="eba52b2e-b77a-47b9-9619-ebda85946883" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="9a366be2-01"<br />
	So the uuid seems to be correct.<br />
	<br />
	I'm not able to boot into Armbian, but the official non-Armbian images from the Radxa site work just fine on this device with the same SD card.<br />
	<br />
	Does anybody know what could be the problem, or any ideas how it can be solved?<br />

	Hi,
</p>

<p>
	I installed armbian_23.8.1_Radxa-zero_bookworm-current_6.1.50 on Radxa Pi Zero <abbr title="embedded MultiMediaCard"><abbr title="embedded MultiMediaCard">eMMC</abbr></abbr> and I have an USB SSD drive connected as storage. Everything worked fine using it as a NAS but if I reboot there is an endless loop of reboots with the core message "scanning bus usb0ff5000000 for devices... Synchronous Abort handler, err 0x56000010". If I disconnect the USB drive it boots fine and when reconnect it after the boot process, the drive works fine. But I really need a system that is able to boot without temporarely disconnecting USB. I tried different combinations of USB with two different hubs or without hub. There are no boot flags on the partitions. I completely deleted all partitions on the drive and tried different kind of partitions and file systems. It does not change anything. Even without any partition it has the same error. I have another USB SSD that also causes a few pages of error messages but after that it does boot (from <abbr title="embedded MultiMediaCard"><abbr title="embedded MultiMediaCard">eMMC</abbr></abbr>). Unfortunately that is the wrong USB drive and does not help. Switching too the newest kernel with armbian-setup also does not work.
</p>

<p>
	Finally I installed Radxa Ubuntu 20 and it boots without any issues while the USB SSD is connected. What can I do to solve this when using Armbian?
</p>

<p>
	Thanks
</p>

<p>
	Tobi

	Hi, 
</p>

<p>
	 
</p>

<p>
	Like the title says the UART overlays are not working on the armbian radxa zero device if I use the official out-of-the-box image. 
</p>

<p>
	 
</p>

<p>
	Using the armbian-config I can enable UART A and B but these changes do not reflect in the /dev/tty devices (using other distros is can see /dev/ttyAML0, /dev/ttyAML1 and /dev/ttyAML4). Unless the devices are called something else i confirm that the overlays are not working. 
</p>

<p>
	 
</p>

<p>
	That being said I want to recompile a armbian image with the correct overlays but I am a complete noob. 
</p>

<p>
	 
</p>

<p>
	Here is my plan : 
</p>

<p>
	 
</p>

<p>
	i successfully compiled a minimal cli armbian image for the radxa zero without any modification (whooohoo)
</p>

<p>
	 
</p>

<p>
	i found the overlays from the official radxa github (whooohoo) : <a href="https://github.com/radxa/overlays/blob/main/arch/arm64/boot/dts/amlogic/overlays/README.overlays" rel="external nofollow">https://github.com/radxa/overlays/blob/main/arch/arm64/boot/<abbr title="Device tree source">dts</abbr>/amlogic/overlays/README.overlays</a>
</p>

<p>
	 
</p>

<p>
	Now i want to include these overlays in the armbian project so that they can be compiled in the image.
</p>

<p>
	Reading the documentation i think that i need to include these files somewhere in the package directory:
</p>

<p>
	<img class="ipsImage ipsImage_thumbnailed" data-fileid="10622" data-ratio="15.06" width="810" alt="image.png.d417993f6ec522bfdcca6b946aa0a8fe.png" src="https://forum.armbian.com/uploads/monthly_2023_07/image.png.d417993f6ec522bfdcca6b946aa0a8fe.png" />
</p>

<p>
	 
</p>

<p>
	or somewhere in the config directory

<p>
	 
</p>

<p>
	I also think I need to include some compiling instructions. 
</p>

<p>
	 
</p>

<p>
	I feel like I'm so close but at the same time, I feel like I'm so far. 
</p>

<p>
	 
</p>

<p>
	Any direction is very much appreciated.
</p>

<p>
	Thank you
</p>

<p>
	 
</p>

<p>
	ps the board is officially supported but I can't find the appropriate topic.

	If I connected the serial port with my device through <abbr title="General purpose input/output">GPIO</abbr> pin 8 and 10 (UART_AO_A_TXD, UART_AO_A_RXD), the Radxa Zero with " Armbian 23.02.2 Jammy" failed to boot.<br />
	If I removed my device from the serial port, zero can boot.
</p>

<p>
	After booting, I connected my device to the UART port, it worked well through /dev/ttyAML0.
</p>

<p>
	Any suggestions? Many thanks!

	I am trying to use radxa-zero with HDMI CEC support on Armbian debian.
</p>

<p>
	I tried all different Armbian debian versions, lsmod never give me module cec
</p>

<p>
	So I took a look at images provided by radxa (<a href="https://github.com/radxa-build/radxa-zero/releases/tag/20220801-0213" rel="external nofollow">https://github.com/radxa-build/radxa-zero/releases/tag/20220801-0213</a>, not armbian ones), cec is loaded by default
</p>

<p>
	 
</p>

<p>
	I think this is the key:
</p>

<pre class="ipsCode">/lib/modules/SOME_KERNEL/kernel/drivers/media/cec/core/cec.ko</pre>

<p>
	This is in their image but not /lib/modules/6.1.11-meson64 folder (I guess also not in other kernel versions)
</p>

<p>
	 
</p>

<p>
	<strong>If that's the case, CEC should not work on any meson64 devices.</strong>
</p>

<p>
	 
</p>

<p>
	I saw CONFIG_CEC_CORE=y is in config. 
</p>

<p>
	btw, another possible related missing module is meson_dw_hdmi.ko
</p>

<p>
	 
</p>

<p>
	Could someone take a look and figure out why they are not there?
</p>

<p>
	 
</p>

<p>
	Really appreciate your help!

	I'm having trouble enabling UART_B on my Radxa Zero Ver 1.51 board using "Armbian 23.02.2 Jammy"<br />
	The idea is to connect a GPS, I had already done this with a Raspberry Pi Zero and it worked fine but I need more CPU capacity and that's why I switched to this board.<br />
	Has anyone had experiences to enable these serial ports?
</p>

<p>

	So far I've tried several images, just wanted to update what has and hasn't worked. I know the rz isn't officially supported but I thought I'd give my feedback and maybe it will help someone. All images were written to <abbr title="embedded MultiMediaCard">emmc</abbr> after first using the radxa-zero-erase-<abbr title="embedded MultiMediaCard">emmc</abbr>.bin tool to erase and mount <abbr title="embedded MultiMediaCard">emmc</abbr> as USB storage.

<p>
	I have a couple of zeros so I went back and forth between the two testing the images. Used DD and Gnome Disks, neither had any luck. Currently running DietPi which seems to be doing well. CoreElec runs good too.

	Hi everyone, I'm using Radxa Zero HW version 1.4, 4GB RAM with 64GB <abbr title="embedded MultiMediaCard">eMMC</abbr>. I used long time armbian on SD card. I decided to install MMC for better performance but armbian crashes APT involving stuffs. By the way, I'm using Rzero with headless and connecting via SSH from Win11 machine. I installed with producer tools directly writing image to MMC and alternatively installed with armbian-config tool from SD card to MMC. In both way successfully boots and connects Wi-Fi. For better diagnostic, how can I get error dump? (I lost SSH connection when its crushed).
</p>

	USB gadget mode does currently not wo<abbr title="Rockchip">rk</abbr> OOTB on Armbian, but it can be enabled easily with a device tree change or overlay:
</p>

<p>
	 
</p>

<pre class="ipsCode">/dts-v1/;
/plugin/;
/ {
	compatible = "radxa,zero", "amlogic,g12a";
	fragment@0 {
		target = &lt;&amp;usb&gt;;
		__overlay__ {
			dr_mode = "otg";
		};
	};
};</pre>

<p>
	 
</p>

<p>
	I can open a PR for adding this as device tree overlay, or enabling OTG OOTB on Radxa Zero, like vendor did: <a href="https://github.com/radxa/kernel/commit/775a467" rel="external nofollow">https://github.com/radxa/kernel/commit/775a467</a>
</p>

<p>
	The latter would be simple. In case of an overlay, I'd need some hint about how to do it best:
</p>

<ul>
	<li>
		Adding it to the general meson64 overlays patch seems to be right: <a href="https://github.com/armbian/build/blob/master/patch/kernel/archive/meson64-6.0/general-meson64-overlays.patch" rel="external nofollow">https://github.com/armbian/build/blob/master/patch/kernel/a<abbr title="Release candidate">rc</abbr>hive/meson64-6.0/general-meson64-overlays.patch</a>
	</li>
	<li>
		But how to prefix or set `compatible` attribute best to assure it can be applied, resp. make clear that it wo<abbr title="Rockchip">rk</abbr>s on Radxa Zero only (as state of testing)?
	</li>
</ul>
