Thank you Don.

(Meanwhile I bought a HP MicroServer. ARM boards were a very good start for me to run my own services but on long term I thought a system with multiple HDD bays is necessary to have more reliability.)
I want to run a Cubietruck with a WD Red 3TB powered by a Leicke NT03010 via official HDD adpater.

First HDD adapter I got caused really strange conneciton problems like random i/o errors accessing the HDD. Second one I bought works somehow but causes power off/restart after around one week after running 24/7.

The point is: same setup but with independent power supply for HDD and Cubietruck works stable over weeks.

Are there any known problems with the official HDD adapter?

I had similar problems but it turned out that the problem is not the adapter. I measured the adapter with a multimeter and a scope and there were not strange signals on it.

No, as it turned out the problem is with the cubietruck mainboard itself. it has the capability to switch off the HDD via a set of mosfet transistors looped in the 5V and 12V power connectors to the HDD. Basically this is a good idea, if you power down the CT it can switch off the HDD completely. however also low drop mosfets have a small voltage drop in on mode. And for my scenario it was sufficient to make my HDD hickup, maybe it is especially picky on the voltage supply. I have a 4TB Seagate HDD attached and when supplied via the power connectors of the CT it regularly quit operation and spun down. I tried with several power supplies, all had the same effect. After I changed the HDD power connector directly to the power supply, circumventing the cubie mainboard the problems were all in a sudden gone. The CT is running now for months many without problems.

So I'd suggest you connect the HDD directly to your power supply and your problems should be gone instantly.

Mainline kernel does not support NAND out of the box, see here:
You'll have to recompile the kernel yourself with the porper settings applied.

From my board I could see this is a capacitor, but as all is SMD it is extremely difficult to recognise any value. I also do think you'll probably have fried the whole board, the capacitor is mainly for stripping of some ripple from the voltage supply and it should run without it when e. g. connected to a battery. So you'll very likely be out of luck. Put the board in the bin and get a new one.

Sounds like this guy here got it running somehow, but I got no reply yet how exactly he did that
Behind any successful software project ‘Testing’ plays a significant role by integrating with all parts of the project. Software testing is a big sphere, but can be broadly classified into two types - Manual Testing and Automation Testing. Both have advantages and disadvantages in its functionalities. In Manual Testing, test cases are performed manually without the help or support of scripts and tools. But in Automation Testing, test cases are performed with the support of scripts, tools and software quickly and without making mistakes.

Manual testing cannot be avoided or removed completely because it helps the test engineers in identifying the uncommon issues and bring out their creativity wherein automated testing scripts are not programmed to identify them. Simultaneously, test engineers or testers get tired of doing the huge amount of work (which includes many repetitive tasks) to be executed during “Regression Testing”, a part of manual testing. Automation testing is the best option in performing such repetitive tasks with the support of the software and application fast and with no mistakes. Automation testing covers almost 70 to 90 percent of the necessary testing efforts put on the software project. In market, there are number of automation testing tools such as Watir, Windmill. Ranorex, SoapUI, Appium, Sahi, Selenium, Testcomplete etc. But Selenium is widely used and recognized as the best automation testing tool.

Brief Overview on Selenium:
Selenium is an open source (free) automation testing software suite designed for web applications used in various platforms and browsers. Selenium is not a single tool but a combination of softwares, each performing different testing needs of the organizations’ software project. Most of the Selenium Quality Analyst engineers zoom in on one or two that mostly counteracts the needs of their projects. Having knowledge on all the tools will give an additional testing inputs to face different test automation chaos. The Selenium suite of tools are well designed and deliver rich set of testing capabilities catering the needs of testing of web applications of various types. These functionalities are highly flexible offering many options in identifying UI elements and comparing expected test results with actual test application behaviour.
The complete Selenium software Suite is comprised of 4 components:

Engineers Behind The Creation Of Selenium Components:

Who Created Selenium?
Jason Huggins, an engineer at ThoughtWorks created Selenium in the year 2004.
Jason was focussing on a web application that needed frequent testing. With this repetitive manual testing of their web application, he observed that testing efficiency got declined. Keeping this in mind, he created a JavaScript program that would control the browser’s actions automatically and named this program as “JavaScriptTestRunner”. Having realized the potential of the program and an idea to enable automate other web applications, Jason made JavaScriptTestRunner an open-source and renamed it as Selenium Core later.

Who Created Selenium RC?
Paul Hammant, another engineer from ThoughtWorks created Selenium Remote Control. With the restrictions imposed by the same origin policy, testing engineers using Selenium core had to install the entire application under test and web server on their own computers. So Paul decided to built a server that will act as an http proxy to ‘trick’ the browser into understanding that tested web application and the selenium core come from same domain. This system was named as selenium 1 or Selenium Remote control.

Who Created Selenium IDE?
Shinya Kasatani, an engineer from Japan created Selenium Integrated Development environment(IDE). The idea behind creating Selenium IDE is to improve the speed in creating test cases. IDE is an extension of firefox that can automate the browser with its ‘record and playback’ feature. In 2006, Selenium IDE was donated to selenium project by Shinya.

Who Created Selenium Grid?
An engineer named Patrick Lightbody developed Selenium Grid. The reason behind developing grid is to address the requirement of reducing test execution times to the possible extent.

Who Created Selenium WebDriver?
WebDriver was created by Simon Stewart in 2006 when web applications and browsers were becoming more restrictive and more powerful with Javascript programs such as Selenium Core.
hello, I've been using your image on the cubietruck for a while, and updated it to Debian Stretch 9.3 today, but the kernel has not been updated and is still 3.4.104-sunxi, how can I upgrade the kernel to a current version 4. Update X? Thank you

yeah, that's right. I have tried and my system breaks :( Now I have started over with armbian and now I'm able to use my encrpt HD :)

I suppose Xenial is not fully supported yet, but changing source and updating Apt (sudo apt-get update) will give access to it.

Full upgrade will lead to non-working system, but if you are lucky you can install individual packages successfully. Bad luck will end up installing everything again from beginning. So - some kind of backup before this might be a good idea.
Cubieboard v3 Images (Cubietruck) / Old images?
« Last post by tilator on January 05, 2018, 07:49:37 am »

I'm testing Cubietruck an I have binary images for flashing directly on MTD. However the downloadable images do not bring MTD any more up in /dev. Some of them give NAND but not MTD.

I suppose writing NAND and MTD is quite different.

My question is does anybody know where is at least one old enough SD-card image which would give support directly on MTD? Or is there any other easy way to do this? I did try to load MTD modules included in some Debian image, but it did not do the trick.
