Hi, I am running the latest Armbian image with Noble + GNOME for the Rock 5C. I have build it using the `compile.sh` script without altering the kernel, desktop enabled, based on Noble, with GNOME, no applications, no extensions. Added the kisak PPA repo afterwards and enabled the panthor overlay for hardware acceleration. Should be close to the `Armbian_24.11.1_Rock-5c_noble_vendor_6.1.75_gnome-kisak_desktop.img` image, I think. With Chromium (few tabs), VSCodium (working on some code) and a couple of terminals open, things were crashing all the time. Here is a reproducable example with Chromium, when navigating to the URL: https://www.geeksforgeeks.org/ulimit-soft-limits-and-hard-limits-in-linux/ sander@rock-5c:~$ chromium [3743:3743:1213/231308.263364:ERROR:object_proxy.cc(576)] Failed to call method: org.freedesktop.ScreenSaver.GetActive: object_path= /org/freedesktop/ScreenSaver: org.freedesktop.DBus.Error.NotSupported: This method is not part of the idle inhibition specification: https://specifications.freedesktop.org/idle-inhibit-spec/latest/ [3743:3795:1213/231308.438912:ERROR:backend_impl.cc(989)] Critical error found -8 [3743:3795:1213/231308.439341:ERROR:entry_impl.cc(955)] Failed to save user data [3743:3795:1213/231308.821432:ERROR:backend_impl.cc(989)] Critical error found -8 [3743:3795:1213/231308.821616:ERROR:entry_impl.cc(955)] Failed to save user data [3743:3743:1213/231308.821621:ERROR:gpu_disk_cache.cc(233)] Failed retry to open blob cache entry: -2 [3845:3861:1213/231317.658891:ERROR:ffmpeg_common.cc(970)] Unsupported pixel format: -1 [4052:4052:1213/231324.240574:ERROR:platform_thread_posix.cc(155)] pthread_create: Resource temporarily unavailable (11) [4057:4057:1213/231324.266795:ERROR:platform_thread_posix.cc(155)] pthread_create: Resource temporarily unavailable (11) [3743:3793:1213/231324.269115:ERROR:zygote_communication_linux.cc(164)] Did not receive ping from zygote child [3743:3793:1213/231324.269180:FATAL:check.cc(361)] Check failed: false.

Every new tab ended up in a "Snap. Your page crashed" view. The root cause seems to be this: ERROR:platform_thread_posix.cc(155)] pthread_create: Resource temporarily unavailable (11) After some web searching, I found that the thread limits are set to a very low value.

Seems that these limits are set or calculated by rockchip linux kernel. After applying a few configuration changes, the system becomes much more stable and I have not had any crashes so far. # /etc/rc.local (updated) echo 16384 > /proc/sys/kernel/threads-max # /etc/security/limits.d/99-nproc.conf (created) * soft nproc 4096 * hard nproc 4096 # /etc/systemd/system.conf (updated) #DefaultTasksMax=15% DefaultTasksMax=infinity After a reboot, the changes are now applied. And no more crashes! And Firefox now works as well. sander@rock-5c:~$ cat /proc/sys/kernel/threads-max 16384 sander@rock-5c:~$ ulimit -u 4096 Hope this is useful to someone else.

I'm having an issue where the prebuilt images dowloaded from https://www.armbian.com/radxa-rock-5c/ (released on Oct 12, 2024) works fine, including WiFi connectivity, even after reboots, but the moment I updgrade the packages (apt update && apt upgrade) and reboot the system, the WiFi network interface (wlan0) simply disappears and can I no longer search or connect to any wireless network.I've flashed both Bookworm Minimal/IOT and Server/CLI Bookworm, e the issue always occur after upgradin packages. the wlan0 does not appear on iwctl neither ip address commands, but the device (AIC Wlan) still appears on lsusb command: $ lsusb Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 004: ID a69c:8d80 aicsemi AIC Wlan Bus 005 Device 002: ID 1a40:0101 Terminus Technology Inc. Hub Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub armbianmonitor output: https://paste.armbian.com/oqewipobin I don't know if there is an issue with the newest kernel update, or if there is some overlay or kernel module for the AIC Wlan chip that is being erased/disabled during the kernel update process. Is there something I can try to reenable the wlan0 interface? or is it just a bronken update?

I am trying to boot my Rock 5C Lite from an NVME drive, but have experienced some problems with the vendor kernel. I followed instructions by amazingfate in this forum to create a small SD card with a u-boot image, ie I created a complete Armbian image (vendor kernel) on an SD card too boot up the Rock 5c Lite A second, small capacity SD card was inserted into the USB port using a USB adapter U-boot was transferred from /usr/lib/linux-u-boot-*/ to the small SD card: dd if=./idbloader.img of=/dev/sda seek=64 conv=notrunc status=progress dd if=./u-boot.itb of=/dev/sda seek=16384 conv=notrunc status=progress My chosen Armbian image was transferred to the NVME drive using Balena Etcher Finally I use the small SD card with u-boot in the SD card slot on the 5C Lite and the NVME drive goes in the NVME hat. I tried two different images from here on the NVME drive Debian 12 (Bookworm) with XFCE and bleeding edge kernel v6.11 Debain 12 (Bookworm) with XFCE and vendor kernel v6.1 The board boots fine from the NVME using the v6.11 kernel, but the implementation seems to be nowhere near complete. The HDMI port doesn't work, the fan is spinning at full speed but is difficult to control because CPU temp is not reported properly, etc. The bord performs well though, and reports eight functioning CPU's. The board does not boot from the NVME using the v6.1 vendor kernel. It tries to start up the kernel but gets stuck. Please see the attachment below for a copy of my complete console output at high verbosity. Would someone be able to help to get the vendor kernel to work? UART-Log_Vendor-Kernel.txt

Login, type "sudo armbianmonitor -u" and copy the URL here. the command failed with the following error : /usr/bin/armbianmonitor: ligne 976: iostat : commande introuvable img used : Armbian_24.8.4_Rock-5c_bookworm_vendor_6.1.75-omv_minimal.img.xz hardware : https://docs.radxa.com/en/accessories/penta-sata-hat https://docs.radxa.com/en/rock5/rock5c 4 ssd samasung evo 870 The image works perfectly when flashed on a SD card and booting from the SD card, the Radxa pentaHat works, the disk are powered (green led for the hat, blue led per each disk). However, when the image is flashed on emmc, the OS boot normaly but the pentaHat does not work, the disk are not powered and not detected by the os (green led Ok, no blue led for the disk) Does any of you have an idea why it works using the SD card and not with the emmc ? is their some settings or overlay that could help fix this issue. I tried the radxa img for the rock5c and it works with either emmc or sd card (https://github.com/radxa-build/rock-5c/releases) Thank you for your answers and help!

Hello, I'm identifying myself has a newbie concerning linux. After some time I reboot my rock5c and it is not booting anymore. Here is what I've done initially: I bought a rock 5c and a penta sata hat. -I installed Armbian_24.5.1_Rock-5c_bookworm_edge_6.8.10_minimal. -I installed OMV (configure some samba shared folder) -I installed ZFS (for that I needed linux headers that I found online because there were not included) -I create a ZFS pull with two SSD. -I installed immich and setup a cloudflare tunel to use it. -I installed plex media server. That's pretty much all I have setup on my SBC. I've done apt upgrade multiple time & update some immich / Plex. Every time I did update I rebooted the SBC. And then yesterday I did an immich & plex update, apt upgrade and lastly rebooted. And my SBC never did come back online. I try to install a fresh armbian install to see if it still boot and it did boot. I'm not sure where to start to get it boot again with keeping has much stuff has I can. I wanted to try this: https://docs.armbian.com/User-Guide_Recovery/#replacing-boot But I'm not sure what Root file system, Kernel, Firmware & Device Tree Binary (DTB) version I should take. Or maybe someone could point me to an other path to fix my install?

I have 2 5C Lite boards a 2Gb and 4Gb version, neither have HDMI output with any stock images either from armbian or radxa. Thru desperation I found an Android image that booted and had screen output, so the HDMI works atleast. After stuffing around I found that the u-boot image extracted from the Rock-5D t2(rsdk) and injected into Rock-5C b1(rsdk) Bookworm_kde image boots and has working screen. Longer story short, getting Armbian 24.11 to work... Narrowed it down from replacing the entire u-boot.itb, I can get a working desktop with kernel version 5.10 Bookworm by removing the rng@fe378000 trngvl section (enabled mali400/bifrost driver in kernel) from u-boot, this atleast has a working system, problem is that there is no fan control with any of the 5.10 builds I've tried. Kernel 6.1 and 6.11 these atleast have fan control but back to no HDMI output, tried the same method of removing rng from u-boot but system fails to boot. At a loss to get HDMI working on newer builds, has anyone had any success or ideas Running the check rk3582 script shows there is a GPU: Rock 5C 4Gb CPU: 7 GPU: Yes Enc0: Yes Enc1: Yes Dec0: Yes Dec1: Yes removed.bin

Is it possible to switch on H264 encoding HW acceleration in chromium browser for WebRTC? I need to send two 2560x720 streams to server from radxa 5c Thanks

Built an Edge/Jammy firmware for a rk3588s2 based system(Radxa CM5). Panthor firmware for GPU G610 is not the right version though in this image. So after boot changed the firmware file, in the /lib/firmware/arm/mali/arch10.8/ folder, to the right version. Reboot produces the same problem though. It does not see the modified file, but still the original, wrong, one. With boot complete and going to the firmware folder the changed firmware is there. I presume that the changes I make end up in an overlay that only is mounted after the boot process. Rewriting the whole 6 GB image, just to change one file, is a bit cumbersome. Is there a way to change the underlying file so that it is used during boot?

I tested some stable armbian images. I want to use the Rock 5C as server, so no desktop is needed. Ubuntu is prefered. First I flashed `Armbian_24.5.1_Rock-5c_noble_vendor_6.1.43.img.xz` wich doesn't work. Log from first boot is attached at the bottom. Second I flashed `Armbian_24.5.1_Rock-5c_noble_edge_6.8.10.img.xz` wich is working well. SSH comes up as usual. Would be nice to use the vendor kernel (6.1.43) instead of the bleeding edge (6.8.10) one, because it is not reccommend and not all features are working.

New Rock 5C work everything fine on Armbian 24 - bookworm stable release but only issue is that Wifi is not working on all stable release except Daily / Rolling releases. It seemed like something is misconfigure about wifi driver. You can see that I tested on both kernel 6.1.43 (stable) and latest edge and it's not working. But this daily release work like charm.
