  1. Hey I try 2 images - stable and nightly (LibreELEC-A20.arm-9.80-devel-20191230203035-9d103bd-cubietruck.img.gz and LibreELEC-A20.arm-9.80-nightly-20200201-a869d6c-cubietruck.img.gz), but after SD card resizing it is coming nothing on the display, seems I have the same error as you described on other forum. Currently I have no cable to connect to the SSH and try to solve it. Sad, but it does not really work out of the box with Cubietruck.
  2. As I see has also nothing related to USB host. Or?
  3. Hello, Just find out that my USB ports are not working. Quick dig shows that the are disabled: # lsusb # dmesg |grep usb [ 0.000000] Kernel command line: root=UUID=e8491c09-2260-4706-a9a4-1f9f96af1232 rootwait rootfstype=ext4 console=ttyS0,115200 console=tty1 hdmi.audio=EDID:0 disp.screen0_output_mode=1920x1080p60 panic=10 consoleblank=0 loglevel=1 ubootpart=5b507211-01 ubootsource=mmc usb-storage.quirks=0x2537:0x1066:u,0x2537:0x1068:u sunxi_ve_mem_reserve=0 sunxi_g2d_mem_reserve=0 sunxi_fb_mem_reserve=16 cgroup_enable=memory swapaccount=1 [ 1.308752] usbcore: registered new interface driver usbfs [ 1.308799] usbcore: registered new interface driver hub [ 1.308867] usbcore: registered new device driver usb [ 2.702281] usbcore: registered new interface driver usb-storage [ 2.736004] usbcore: registered new interface driver usbhid [ 2.736007] usbhid: USB HID core driver [ 2.858064] usb0-vbus: disabling [ 2.858070] usb1-vbus: disabling [ 2.858079] usb2-vbus: disabling I try to check overlays, but there is nothing related to usb: I try to run sunxi-pio -m PB10<1><0><default><1> sunxi-pio -m PB11<1><0><default><1> as described here: bust without success. Provided doku: /boot/dtb-4.19.57-sunxi/overlay/README.sun7i-a20-overlays does not say anything about USB hosts and I see that there is no PB10 and PB11.

  4. I did as you told: install Armbian on a new SD, bootup, create user and set passwords. After I adjust /boot/armbianEnv.txt to set UUID to my drive and then rebooted successfully. One point, because older SD was going into RO mode, I have badly installed package: initramfs-tools, and future apt upgrade were finished with an error. So I have to reinstall it by command: sudo apt install --reinstall initramfs-tools:armhf After this everything works good, thanks! UPDATE: I was a bit wrong, Kernel has some problems, this is an error when I try to run iptables: $ sudo iptables -vnL modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/4.19.57-sunxi/modules.dep.bin' modprobe: FATAL: Module ip_tables not found in directory /lib/modules/4.19.57-sunxi iptables v1.6.1: can't initialize iptables table `filter': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. I try this and that with update and upgrade, but helps only to re-install the same kernel via armbain-config>System>Other>choose the same Kernel as I have had before.
  5. Thanks! I will try do this. Last year I did the same as you told and it did not work for me... Lets see now. Is there is a way to automate this prcess? E.g. added User (copy /etc/passwd and /etc/shadows)?
  6. Hello, I have trouble with my SD Card - it goes in Read Only mode. What I have: I have Running System from the HDD (installed by nand-sata-install command) My Cubietruck is online for now, but I'm afraid do switch it off. I try to run dd command to make a backup of RO SD card and reuse image on a new SD card, but it does not succeed: # dd if=/dev/mmcblk0 bs=10M | gzip -c > /media/dataPartition/sdcard.img.gz dd: error reading '/dev/mmcblk0': Input/output error 0+0 records in 0+0 records out 0 bytes copied, 0.00503184 s, 0.0 kB/s I read the forum regarding backup and restore and my question is following: Is there is a way to prepare new SD card and simply insert it into the running machine and reboot without starting from zero? Like set only the boot partition and clone the rest from hdd? Try to clone boot from the old SD? Make it sense to pull out old SD card and try to make backup of it on Laptop and then write this image to the new SD card?
  7. And after update to latest Armbian I noticed that it is not there. Update was done from Ubuntu 16.04... And before I can get AC Power supply status via: cat /sys/class/power_supply/ac/present Now I could not find anything AC Power supply related... Where is all this gone? ls -la /sys/class/power_supply total 0 drwxr-xr-x 2 root root 0 Aug 20 10:26 . drwxr-xr-x 61 root root 0 Aug 20 10:26 .. lrwxrwxrwx 1 root root 0 Aug 20 10:26 axp20x-battery -> ../../devices/platform/soc@1c00000/1c2ac00.i2c/i2c-1/1-0034/axp20x-battery-power-supply/power_supply/axp20x-battery lrwxrwxrwx 1 root root 0 Aug 20 10:26 axp20x-usb -> ../../devices/platform/soc@1c00000/1c2ac00.i2c/i2c-1/1-0034/axp20x-usb-power-supply/power_supply/axp20x-usb UPDATE: I found it, thanks to this tread: ls -la /sys/power/axp_pmu/ac total 0 drwxr-xr-x 2 root root 0 Aug 20 10:33 . drwxr-xr-x 17 root root 0 Aug 20 10:33 .. -r--r--r-- 1 root root 4096 Aug 20 10:43 amperage -r--r--r-- 1 root root 4096 Aug 20 10:43 connected -r--r--r-- 1 root root 4096 Aug 20 10:43 used -r--r--r-- 1 root root 4096 Aug 20 10:43 voltage
  8. How to disable it correctly: Only config edit will not give you correct effect.
  9. I read zram and log2ram config and source and recognized that zram will evaluate config of log2ram, so if I disable it in config - everything works. Only issue - truncate operation is still in cron and script does not look into config by executing... This bring must be disabled in cron. Yes, I forgot to say about this... daily script was commented # cat /etc/cron.daily/armbian-ram-logging #!/bin/sh #/usr/lib/armbian/armbian-ramlog write >/dev/null 2>&1 Thanks a lot!
  10. Long story short, to disable arbain-ramlog: 1. Change in /etc/default/armbian-ramlog ENABLED=false 2. Disable in cron root user truncate-logs by editing /etc/cron.d/armbian-truncate-logs (just comment the line) like this: # 0,15,30,45 * * * * root /usr/lib/armbian/armbian-truncate-logs 3. Delete /etc/cron.daily/armbian-ram-logging or comment it like: #!/bin/sh #/usr/lib/armbian/armbian-ramlog write >/dev/null 2>&1 4. Restart Server. Because armbian-zram is connected to ramlog service and will read config of it. It will not create compressed in-memory folder for logs. Without restart it will not be used properly and you will loose your logs.
  11. Also try to solve this problem. I create a script that will try to send Warning Email and and shutdown the system as soon as it goes below 10%. I put it in cron hourly and script should automatically check and do loop if battery discharging and below e.g. 80%. E-Mail is needed because last time I did not know that my power supply died and I did not know why sever stopped. This version is also producing logs that could be checked after cubietruck fails. That helps for trouble shooting, e.g. to find out that power supply could not produce enough current to charge battery. Log output example: Tue Oct 16 10:01:03 CEST 2018 - Ok. Battery Full - 100% left. AC is online with current 0.222 A. Battery health is Good.
  12. System Information: - Cubietruck with Ubuntu 16.04 - armbian-config 5.62 - armbian-firmware 5.60 - armbian-tools-xenial 5.60 Hallo since last few updated I've noticed that I have no logs... With some update armbian ram logging was enabled and all logs moved to log.hdd folder, but not all of them are filled up after this operation. I did disabled armbian-ram-loggin wia editing /etc/default/armbian-ramlog: ENABLED=false After this services was disabled, but no logs filled in a log folder... Also no log rotation happens.
  13. Try to wait:D I have the same "issue" shutdown or reboot takes time (around 2 minutes) before it goes down, I did not check, but seems some trim operation with SD card, or something. In time between shutdown/reboot command when LED blinks cubietruck is not reachable via network.
  14. I find out what was wrong. It was my mistake with mysql and iptables. Basically I setup wrong settings for iptables and localhost (like from to, but this will cause situation when MySQL port 3306 will not accept some of inbound connections from e.g. 10.0.x.x that is also "local". This will cause issue when CPU load is extremely high, but you could not recognize app/service that cause it, only "TIME+" can give a hint on root mysql process. It is hardly to catch, because issue will not accrue till reboot, and you do not need to reboot the system for iptables. This cause it last time: iptables set long time ago and then reboot was needed that shows the problems. Today I did the same mistake on a fresh installed system. I set iptables (orange pointer) and reboot the system (green pointer) later and it starts... SOLUTION: To solve the problem it is needed something like this in iptables: -A INPUT -s -j ACCEPT
