It's working fine. Thank you for all the notes.

Thank you.

Hi Forum, Please let me take a "low level" question about what I experienced on my CT. It should be my misunderstanding but it would be good if someone could help to clarify. On my CT udev mounts a USB device then starts a bash script in the background. This script lunches some bash threads and waits for them to complete. The threads has no common job on any file or resource. In the third level of nesting cp -r chrashes without any error message. It leaves the logging sentence in the middle, so it's really chrashes. rsync does the same but for different files. The scripts are fully functional if I start them from a root console. Even if started in the background. Is there any constraint that should be taken into account in these cases on CT or on Armbian or regarding udev rules? Any tools for such bg processes? Other than logfiles. Any idea welcomed. Thank you in advance, T

Hmm... But this speed degradation doesn't proove me that it takes a whole night to upgrade the system and in the morning I can't see any progress. Even if the boot up speed is less then one minute from switching on to get a login prompt.

I'm using a 16GB Samsung EVO, but I'll do the test.

Hi Igor, It's there http://sprunge.us/SNTU Regards, T

Hi Igor, Thank you for the link. I'll update the post with the link as it gets ready. What "low quality SD card" means? What is the parameter that Linux counts on? Is it too slow? Endurance can't be seen by L only if the card fails. Regards, T

Hi Forum, My CT with "Armbian_5.14_Cubietruck_Debian_jessie_4.6.2" image fails to complete apt-get upgrade and dist-upgrade. I haven't installed or removed any package, simply used the original image as it is. It starts the process, gets the packages, unpacks, starts setting them up and hangs at compiling the new headers. I left it working a full night but found with doing nothing. No cpu or disk activity was seen. Has anyone seen this before? Any idea? Thanks, T

It looks the issue is solved, CT shuts down correctly. Module g_mass_storage was preventing the normal shutdown. I added an init.d script to remove the module during shutdown. Just if someone had something similar I uploaded the script as txt file, otherwise I had no rights to attach. So, thank you very much all of you. shutdownhelper.txt

I'm using the onboard peripherals only. USB slot is empty. But I loaded g_mass_storage. That's the one I haven't tried to rmmod before shutdown.

How can I know the board revision? Tomorrow I will try with the original image without any extra package installed. Now I use hostapd, dnsmasq samba. I tried to stop all of the services I installed but it didn't help.

Both From battery and From the coaxial power plug. It behaves the same if detaching te external power. As if the last i2c commands were not sent to the pmu.

Hi Forum, My CT with "Armbian_5.14_Cubietruck_Debian_jessie_4.6.2" image doesn't shut down. Neither short push of power button nor shutdown -P (issued as root) doesn't really power off the board. The red LED is lightning and the display is ON, it halts after reporting "Reached Target Shutdown". The board is OK, for a long push of PB it powers off and with a Cubieez image it shuts down well. Has anyone seen this issue? What to do with it? Thanks, T

Any idea?

Hi Forum, "modprobe g_mass_storage file=/dev/sda1 removable=yes stall=0" doesn't work on 3.4.112 but works on 4.6.2.
