@tkaiser follows the output iozone: http://sprunge.us/eKjV by the way, what does this command do? But actually with dd, I get pretty much the same results for different bs. like bs=128M count=20 The annoying errors are due to some backlight control module, that has to be disabled. Not from the usb, at least it looks like. @Igor Thats very much true. It must be even more sad to the chip maker. At least they give boards for free. And sorry for the naive question, but how would I configure armbiam compile to clone from the Allo instead of Lemaker? Thank you guys.

From those I was only aware of the Lemaker. A quick browse on the Allo repo, and they seem more active. I found a commit that seems to enable the USB3: https://github.com/sparkysbc/Linux/commit/3867b3fd05d2998a5503bb6c72a4946b5580a563 Pity that the community did not grow. Do you think it is worth trying to compile Allo's kernel, or to put any effort on this board?

@Igor So far I have tested with your latest Armbiam and their official Debian. I should test with Android as well. Would it give any help? The kernel from Xapp-le last commit was june 2016... They also have this ubuntu snappy core, but I did not compile it yet, and I could not find the image for that. @tkaiser It is Mb/s.. Mega bytes... For that I used the command, after mouting and while inside a folder of the disk I wanted to test: dd if=/dev/zero of=temp.img bs=2G count=1 oflag=dsync This eliminates the possibility of reading from the input file (if) to delay the writing.

But my biggest issue now is: I can only get 18 Mb/s with the USB3 using the latest Armbiam. Know anything about it? Is that a limitation of the current kernel release? Surprisingly, during the file transfer the CPU usage does not exceed 25% of a single core.

On your text: Thanks again.

Thanks Igor. I did that, in a brand new image. Worked out for since then, but have just crashed. I'm running a demanding software there, but it does not hurt even weaker boards I have. What could it be? Cheers.

I'm also interested on that. Would appreciate any effort on that direction. Dont have expertise on that, but if I can help... Thanks

Ok, it makes sense. I did the apt-get upgrades available. What would u suggest me to try? Or should I go back to the orignal image? Thanks again.

From /etc/armbian.txt: Title: Armbian 4.2 Cubietruck Ubuntu trusty default (unofficial) Kernel: Linux 3.4.108 Build date: 26.08.2015 I think it is the last one. I use to have instability issues before too. Is ubuntu worst in any way compared to the debian distro? Should I upgrade the kernel? How can I figure out why, and maybe help on that? Thanks a lot.

Hi. Can anybody give me any idea on how to find out why it is crashing? I recently moved to this distro, and it is now crashing after 1 to 4 days of continuous usage. The thing is, I have no idea how to find out why it is happening, and how to fix it. Which log should I go for? I was running this Aruntu before, and never had this issue, which seems to show that this is not an hardware issue. Best, João

This address does not exist in my ubuntu ct distribution. Although there is /sys/class/leds/orange\:ph20\:led2/trigger This file have a sintax like a b [c] d, to enable trigger c. The issue is that this file can not be writen in any way. Is this config somewhere else?

How can I disable the auto login as the root user in the cubietruck ubuntu (XFCE)? That does not sound a good idea. How could I auto login with a different user? The GUI settings editor "display chooser" inside Session Startup doesnt work. I've been looking around how to do that, but in this case I cant find the config file which was supposed to be inside /etc/lightdm/ Thanks and congratulations for your work.
