I don't think I forgot anything. I was just curious about the conditions for the current version, since these sentences are relative generic and don't list issues, before I layout the details that I noticed. I flashed the image to a SanDisk Ultra, A1, Class 10 sdcard. System booted fine, but was relative slow which seemed to be related to constant sdcard speed switching issues. The following was constantly going on in the logs.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Marco Schirrmeister <mschirrmeister@gmail.com> Date: Sat, 6 Dec 2025 23:56:46 +0100 Subject: [PATCH] arm64: dts: rockchip: rk3576-nanopi-r76s: fix sdmmc/sdhci coexistence The NanoPi R76S (RK3576) features both a DW‑MMC controller for the microSD socket (sdmmc) and an Arasan SDHCI controller for the on‑board eMMC (sdhci). When both were enabled, the shared I/O voltage rail caused initialisation conflicts: the eMMC required 1.8 V signalling while the SD card logic expected 3.3 V. This patch aligns the DTS and U‑Boot configuration so that both storage controllers operate correctly: - Enable CONFIG_MMC_SDHCI and CONFIG_MMC_SDHCI_ROCKCHIP in U‑Boot. - Add explicit `vmmc-supply` and `vqmmc-supply` properties to the eMMC (sdhci) node. - Add `no-1-8-v;` to the SDMMC node to keep the µSD socket fixed at 3.3 V. With these adjustments the board can access both the microSD and eMMC devices simultaneously, and U‑Boot can boot directly from either medium.

If this changes are good or bad, I have absolutely no idea.

The page for the NanoPi R76S has also an edge kernel (6.18) image. I noticed some issues related to sdcard and emmc. I know edge images are not officially supported and that is fine. But given the image is available I would like the parameters/configuration/conditions for the current available image. Could you explain the background or assumptions behind the 6.18 edge image for the R76S? (e.g., test conditions you used when building it)

With the following options configured as a built-in module, the issue does not happen anymore on a poweron. CONFIG_TYPEC=y CONFIG_TYPEC_TCPM=y CONFIG_TYPEC_TCPCI=y CONFIG_TYPEC_FUSB302=y CONFIG_PHY_ROCKCHIP_USBDP=y I can create a pull request for the linux-rockchip64-edge.config file. But not sure what the general consensus on the kernel options for Armbian kernels is. Maybe it is also fixable via some code change, but that would be something for a real kernel developer.

This also happens on other kernels. Issue is present on final 6.18.0 kernel as well as on the older 6.12 kernel. It seems to be related to some kernel options that are set to "m". Need to figure out which kernel options would need to be set to "y" (built-in) on Armbian to avoid this issue on power-on.

Just an information about the `edge` kernel (6.18) when used on the cm3588-nas system. The rtc driver is not initialized on a `poweron`. After a poweron, you will see the following in the log. Nov 11 01:17:10 uhutest kernel: rtc-hym8563 6-0051: could not init device, -6 Nov 11 01:17:10 uhutest systemd[1]: System time advanced to built-in epoch: Tue 2025-11-11 01:17:09 CET If you have `fake-hwclock` running, you will see the following a moment later. fake-hwclock restores the time, but the service will not properly start, because of the rtc device error.

You would need to restart the fake-hwclock service, if you want that it saves time before the next restart. If you do a `restart` of the system, the rtc device will get properly initialized and time is good. Following is seen in the logs.

The following patch mentioned here works as a pure workaround. https://patchwork.kernel.org/project/linux-rockchip/patch/20220608161150.58919-2-linux@fw-web.de/ Lets see how the development of kernel 6.18 goes and if the final version will not have this issue.

The 6.12.17-current-rockchip64 now works for me just fine. Wanted to test again and capture some verbose boot logs if it fails. But now it works just fine. Not sure if it is related to the patch from the pull request 7887, that was mentioned above.

On my OPi4LTS I do not have EMMC and it is stuck. Like I wrote it is stuck during hardware initialization, so I think it has no problem with finding the right kernel to boot.

I think the "apt list --upgradable" still shows packages that are hold. Run a "apt upgrade" and in there you should see what is held back. If all looks good, you can hit Y.

Of course can the OPi4LTS users install the rolling image. Which works fine, so no need for a custom build. But typically you don't want to run this on a production or stable machine. You never know what else will break down the road. Given that this works, the question is why does the 6.12 kernel images break the stable supported version. There is also no good way to debug, since all you see is initializing the hardware and then it is stuck at one point. But it is not fully clear what it does not like.

The real question is, why is is not booting or if it is supposed to be working. The download page has all kinds of images for the OPi4 with kernel 6.12, but it seems they do not work?

I would go with, like you wrote, ext4 or xfs. If something breaks, you can still mount the disk on any other linux system without any issue. Ext4 should also not have any problems with big file sizes. I am running xfs without any problems since years. Even if there was a hard crash, the filesystem could easily be mounted since nothing really happened on it or the recovery was smooth. I would probabyl still argue that ext4 is even more robust. For a simple disk to store some data it might still be the best choise.

I noticed the same and since I mainly run server stuff and don't rely on a monitor, my current workaround is modprobe -r synopsys_hdmirx. Don't know what this module is for, but console output is still working via hdmi. And to do it permanently, I have the following: root@dumpster ~# cat /etc/modprobe.d/hdmi.conf blacklist synopsys_hdmirx

A while ago I debugged the ssh problem and added some comments in this thread here. I don't remember if I used bookworm or trixie. Seems to me a timing issue or in which order things start. For now, whenever I do some dev work, I just do either another reboot after the first setup or restart the sshd service.

I think this issue here https://github.com/htop-dev/htop/issues/1160 describes the problem. Might be a problem that needs to be fixed within htop. If you are willing to switch tools, have a look at btop. That should give you should give you the overall temperature.

@Efe Çetin, PR is created. https://github.com/armbian/build/pull/6276 Bear with me, it is my first PR. So let me know whatever is wrong or needs to be changed.

Thank you for the confirmation @Vijay Gill. Here is the patch I use. I did also add the poweroff support. Splitting it into multiple files might be better, but it is good enough for my test builds. root@dumpster /m/t/t/n/build (main)# cat userpatches/kernel/rockchip-rk3588-edge/1000-arm64-dts-fix-rtc-add-poweroff-support-Orange-Pi-5-Plus.patch From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: John Doe <john.doe@somewhere.on.planet> Date: Mon, 29 Jan 2024 12:51:13 +0100 Subject: Patching kernel rockchip-rk3588 files arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts Signed-off-by: John Doe <john.doe@somewhere.on.planet> --- arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts b/arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts index 88bfce6237db..70cc6bd5a0af 100644 --- a/arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts +++ b/arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts @@ -462,11 +462,11 @@ &pcie3x4 { }; &pinctrl { hym8563 { hym8563_int: hym8563-int { - rockchip,pins = <0 RK_PB0 RK_FUNC_GPIO &pcfg_pull_none>; + rockchip,pins = <0 RK_PB0 RK_FUNC_GPIO &pcfg_pull_up>; }; }; leds { blue_led_pin: blue-led { @@ -572,10 +572,12 @@ pmic@0 { pinctrl-names = "default"; pinctrl-0 = <&pmic_pins>, <&rk806_dvs1_null>, <&rk806_dvs2_null>, <&rk806_dvs3_null>; spi-max-frequency = <1000000>; + system-power-controller; + vcc1-supply = <&vcc5v0_sys>; vcc2-supply = <&vcc5v0_sys>; vcc3-supply = <&vcc5v0_sys>; vcc4-supply = <&vcc5v0_sys>; vcc5-supply = <&vcc5v0_sys>; @@ -592,11 +594,11 @@ pmic@0 { gpio-controller; #gpio-cells = <2>; rk806_dvs1_null: dvs1-null-pins { - pins = "gpio_pwrctrl2"; + pins = "gpio_pwrctrl1"; function = "pin_fun0"; }; rk806_dvs2_null: dvs2-null-pins { pins = "gpio_pwrctrl2"; -- Created with Armbian build tools https://github.com/armbian/build

Building on an Orange Pi 5 works just fine. I build image for the OPi5+ and Rock5b on my OPi5. @Gullik, what improvements do you expect to see in rc2 or rc3? Like Werner wrote the other day, he has not changed it to rc2, since there were no relevant changes. Same most likely goes for rc3. There are no commits for rk3588 or at least none where you would say, I need this right now. Even if there are changes, many are board specific.

I think that is normal. Same for me, fut fan should stop and if you measure the power on the outlet, you will see it is not drawing anything. I don't remember how it behaves on the Rock-5b. But I can power it on another day and check.

If you installed an image from the nightly builds, then the apt source list should have the beta repo in it. Which means you will see kernel and other updates relative often. root@orangepi5-plus ~# cat /etc/apt/sources.list.d/armbian.list deb [signed-by=/usr/share/keyrings/armbian.gpg] http://beta.armbian.com trixie main trixie-utils trixie-desktop

The edge or mainline kernel version is defined in config/sources/mainline-kernel.conf.sh. So yes, an update/PR to that file is needed, I think. If you want to change to your own newer version, you can define it for the compile.sh script. builder@dumpster /m/t/t/n/build (main)# cat userpatches/lib.config KERNELBRANCH="tag:v6.8-rc2"

That looks about right. Load around 1 and the hym8563 changes for me between 5-10%. Here is the patch I created for the OPi5+ and apply during my image builds. Tested with 6.8-rc1, rc2 and rc3 with bookworm and trixie. I hope that this things make it sooner than later in the mainline kernel. builder@dumpster /m/t/t/n/build (main)# cat userpatches/kernel/rockchip-rk3588-edge/1000-arm64-dts-fix-rtc-add-poweroff-support-Orange-Pi-5-Plus.patch From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: John Doe <john.doe@somewhere.on.planet> Date: Mon, 29 Jan 2024 12:51:13 +0100 Subject: Patching kernel rockchip-rk3588 files arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts Signed-off-by: John Doe <john.doe@somewhere.on.planet> --- arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts b/arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts index 88bfce6237db..70cc6bd5a0af 100644 --- a/arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts +++ b/arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts @@ -462,11 +462,11 @@ &pcie3x4 { }; &pinctrl { hym8563 { hym8563_int: hym8563-int { - rockchip,pins = <0 RK_PB0 RK_FUNC_GPIO &pcfg_pull_none>; + rockchip,pins = <0 RK_PB0 RK_FUNC_GPIO &pcfg_pull_up>; }; }; leds { blue_led_pin: blue-led { @@ -572,10 +572,12 @@ pmic@0 { pinctrl-names = "default"; pinctrl-0 = <&pmic_pins>, <&rk806_dvs1_null>, <&rk806_dvs2_null>, <&rk806_dvs3_null>; spi-max-frequency = <1000000>; + system-power-controller; + vcc1-supply = <&vcc5v0_sys>; vcc2-supply = <&vcc5v0_sys>; vcc3-supply = <&vcc5v0_sys>; vcc4-supply = <&vcc5v0_sys>; vcc5-supply = <&vcc5v0_sys>; @@ -592,11 +594,11 @@ pmic@0 { gpio-controller; #gpio-cells = <2>; rk806_dvs1_null: dvs1-null-pins { - pins = "gpio_pwrctrl2"; + pins = "gpio_pwrctrl1"; function = "pin_fun0"; }; rk806_dvs2_null: dvs2-null-pins { pins = "gpio_pwrctrl2"; -- Created with Armbian build tools https://github.com/armbian/build

If you want poweroff working, then you need to apply the following patch. https://lore.kernel.org/lkml/pqvmguq77qbxmuxsushrz4ykxtmvkugirbxnckmbfk47gx2u5n@cz2kllnjr6ba/T/ Just out of curiosity, do you see a kernel irq "hym8563" process with high cpu usage? 10% give or take.

Which image did you use, that you do not see the hym8563 irq issue on your OPI5+? Would like to try that exact image.

Final comment for the sshd start problem on some systems during the first boot. That should probably discussed in its own thread though. It really seems to come down to the start time of the armbian-firstrun service. I guess it starts too early. Either of the following changes in the armbian-firstrun.service file will have it started later and avoids the issue. [Service] Type=idle or [Unit] After=multi-user.target

I know now why sshd is not running. The directory /run/sshd is missing. dpkg-reconfigure openssh-server or service ssh restart from armbian-firstrun delete the directory if it is there. Just restarting sshd via the console recreates it (as defined in its service). sshd -t Missing privilege separation directory: /run/sshd It can easily reproduced by enabling the armbian-firstrun service and a reboot. It runs through its things on the next boot and the directory is gone. I assume it has to do with the way the sshd restart is executed. Something where it is executed in a script, that in turn is executed via a systemd service during a boot. If you restart it via the console shell where you logged in, it works just fine.
