No, it's not 🙂 If you need something stable and safe, don't waste money on these crappy chinese sbc. Buy a LP Intel like a Dell Wise 5070 on ebay (~80/90€ with a Celeron J, 4/8GB RAM and a SSD) and install Debian o CentOS. is rock-solid and requires only 5/8 Watt.

@718aba Install the 23.11.2 on sd and block the kernel update in armbian-config, as recommended by Giulio. Configure everything and then make a full compressed backup of the whole SD with usbimager (gitlab).

Yes Giulio, it's probably the kernel... no version after 6.1.x works

Armbian 24.2 is broken on Orange PI PC2 (Debian Bookworm CLI) Latest stable community release: https://github.com/armbian/community/releases/download/24.5.0-trunk.123/Armbian_community_24.5.0-trunk.123_Orangepipc2_bookworm_current_6.6.20_minimal.img.xz With update 23.11 -> 24.2 the orange pi pc2 no longer starts. I tried a new sd installation and it too does not appear on the network. Right now I don't have a serial cable to check but it is possible that the network driver is missing or not working. SD, SBC and PSU are 100% working: a revert to 23.11.2 makes it work perfectly.

It's a problem, "armbianmonitor -u" is broken, all free service (pastebin, ghostbin, etc...) are limited to 512kB-1,5MB. Now is not possibile to upload all necessary data. SBC is crashed on 20.09 (boot at 13:05, crashed at 15:35*), on 21.09 (boot at 14.00 then crashed at 17.37*) and on 22.09 (boot at 13:35 then crashed at 23.12*). (*): timestamp of the last picture shooted and processed. Sunday (23.09) I've changed the vm.swappiness to 30 and the problem has been solved. Now I need the following directions to help you: - when to run the "free -m" command - how to send the log if armbianmonitor does not work - how long to run the indicated scripts I need at least 1 or 2 weeks to do everything...

vm.swappiness=100 https://ghostbin.com/paste/vrt5t With vm.swappiness=30: system work fine With wm.swappiness=100: system work fine for a random time (3-12 h), then hang with ssh unreachable, yellow ethernet led fixed on, pihole/motioneye/rpi monitor web pages unreachables. Hardware: OrangePI Zero v1.4 - Sandisk uSD 16GB U1 A1 (checked, good healt) EXT4 - Toshiba USB Stick 32GB (checked, good healt) F2FS, USB PSU FriendlyARM 5V/3A (checked, good healt).

After warm reboot... ~70-72°C it's a badly reported temperature, correct value -measured with a Fluke thermometer- is ~65°C on the SOC heatsink. It's normal, the scb works as a visual motion analizer (1 h264 hd stream) 24/7 since mid 2017. Yes, I've starting monitoring... They are not... totally different purpose or software stacks... and power outlet. Anyway now my OPZ works stable again with Armbian 5.60 (with vm.swappiness set to 30-60).

@ag123 The good thing: reducing the value to 30 (vm.swappiness = 30) seems to solve the problem. Now I got ~22 h uptime without any hang... The bad one: an heavy zram usage on my AMD/Debian 9.5 microserver freeze the system (both gnome shell and ssh). :-| I think zram has some problems with Debian...

Interesting... I'll change swap threshold to a more conservative value to 30 and I'll test it for 24/48h.

Still stability issues on stable v5.60 (v5.59 upgraded to 5.60). I can not have an uptime over 3-12 hours (it is not reachable via ssh or webgui). SD and psu are OK. The system run stable on old v5.38 (january 2018) with same setup for weeks. Orange Pi Zero 512/v1.4 system log: http://ix.io/1ngD

All right! Native zRAM implementation work very well in Armbian (next) v5.59 (tested on my Pi Zero and PC2). EDIT (problem with v5.60 and vm.swappiness = 100):

My Orange Pi PC2 work fine with Stretch (mainline, 4.14.48) between 35 and 65 °C. I got only a minor (but annoying) problem: the board start overheating after a shutdown (sudo shutdown -h now) and reach >70 °C after few minutes. Is it a kernel problem? Or a hardware design fault?

They have released the first version (07_2018) https://bootlin.com/blog/allwinner-vpu-main-goals-delivery/ https://linux-sunxi.org/Sunxi-Cedrus#2018.07_Releases

Me too... with an old HP z400 Workstation (Xeon W3530, 12GB ECC DDR3 and a SSD Crucial MX300) build process is quite fast.

An extrusion process - compared to cnc machining - isn't more cheaper (economically and energetically)? Like new Asus case for Tinker Board: https://www.asus.com/Single-Board-Computer/Tinker-Fanless-Aluminum-Case/

Yes... https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/gpu/arm,mali-utgard.txt

It looks like Yong Deng's patch for V3s CSI. +// SPDX-License-Identifier: GPL-2.0 +/* + * Copyright (c) 2011-2018 Magewell Electronics Co., Ltd.

This sounds very interesting! But ... I can not find the interface driver (sun6i_csi). This is the Maxime Ripard's patch to mailine kernel or another one? For the testing: I've a Orange Pi PC2 H5 and a OV5647 NoIR CSI.

(disclaimer) No itention to make a Frankendebian (https://wiki.debian.org/DontBreakDebian) but ubuntu package "zram-config" works perfectly. I tested it for two weeks in a: Orange PI Zero 512MB Armbian Stretch 5.40 4.14.18, Orange PI PC2 Armbian Stretch 5.40 4.14.18, AMD Sempron microserver Debian Stretch 9.4 4.9.0-6-amd64. A short tutorial: 1. Download zram-config package (it's a universal package, it does not matter the architecture in use) wget http://de.archive.ubuntu.com/ubuntu/pool/universe/z/zram-config/zram-config_0.5_all.deb 2. Install it sudo dpkg -i zram-config_0.5_all.deb 3. Remove the installer rm zram-config_0.5_all.deb 4. Check vm.swappiness cat /proc/sys/vm/swappiness (must be 60, default) 5. If not (i.e. "cat /proc/sys/vm/swappiness" return "1" ) change it to "60" sudo nano /etc/sysctl.conf and add "vm.swappiness=60" at the end of file ... and reboot 6. check zRAM service sudo zramctl NAME ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT /dev/zram0 lzo 437,8M 5,2M 1,4M 1,9M 2 [SWAP] /dev/zram1 lzo 437,8M 5,2M 1,4M 1,9M 2 [SWAP] 7. (optional) change lzo compression to lz4 sudo nano /usr/bin/init-zram-swapping # initialize the devices for i in $(seq ${NRDEVICES}); do DEVNUMBER=$((i - 1)) echo $mem > /sys/block/zram${DEVNUMBER}/disksize mkswap /dev/zram${DEVNUMBER} swapon -p 5 /dev/zram${DEVNUMBER} done to... # initialize the devices for i in $(seq ${NRDEVICES}); do DEVNUMBER=$((i - 1)) echo lz4 > /sys/block/zram${DEVNUMBER}/comp_algorithm echo $mem > /sys/block/zram${DEVNUMBER}/disksize mkswap /dev/zram${DEVNUMBER} swapon -p 5 /dev/zram${DEVNUMBER} done 8. restart the service sudo systemctl restart zram-config.service 9. check new compression algorithm sudo zramctl NAME ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT /dev/zram0 lz4 437,8M 5,2M 1,4M 1,9M 2 [SWAP] /dev/zram1 lz4 437,8M 5,2M 1,4M 1,9M 2 [SWAP] 10. check the zRAM priority over file swap cat /proc/swaps zRAM devices must be at priority "5", swap file at "-1" or "-2" 11. finish :-)

An Asus Tinkerboard (Mali-T764) or a Rock64 (Mali-450MP4)?

If you have that already, you'll need the options CONFIG_CMA and CONFIG_DMA_CMA enabled in your kernel configuration."

Ops... :) Zero plus 2 is the H5 version? CPUFreq is in WIP stage also for the H5... all H boards have problem scaling down in idle with kernel 4.14.
