HI all.
Just want report that after i filled out a bug issue report, cubieboard added the missing source files for the u-boot loader and fixed the compile build errors.
Now without any problems anybody can compile and build the legacy u-boot loader from sources for the Cubie Truck Plus board.

https://github.com/cubieboard/Cubietruck_Plus-u-boot/commit/a2f7a0903f4c393163fc656ae2af557bcaaff3f6

If everything works like expected we should have beginning of next week probably also some results related to mainline bootloader for the cubietruck plus. :-)
Will report back on Monday 17 May more about it.

Mainline Linux Kernel hopefully around end of May.
Happy looking forward running my Cubietrcuk Plus Board wiht newest software :-)

@Keiser Thanks a lot for sharing your highly valuable experience related to the Sata Interface.
I buyed it for several reasons its not my only allwiner board. have dozens of orange pi's too :-)

I just love new hardware like the H8 CPU.

Hi Igor!

Thanks a lot for the Info!

I was able in the last hours to finaly compile, build and run successfull the u-boot loader CubieTruck uploaded to GitHub for the CubieTruck Plus 5 Board.

The Code itself that CubieBoards uploaded to github is not complete so i had to add missing files to the code to finaly compile it and run it on my CubieTruck Plus board.

After this i maked a Patch from this u-boot CubieTruck Plus 5 source repository to the original allwiner one to find all the missing parts and changes so i am able to apply them

later to mainline u-boot.

Here is the Link to the Diff Patch for the CubieTruck Plus 5 in case anybody is interessted.

https://mega.nz/#!OIpxmCiK!v8W4axaEBSyhwwGNBhIn7oCK66xxhrEiPZMo-Er8MG0

The Patch Itself need some cleansing but its full complete.

I see some interessting lines that can be used to get mainline u-boot sources to finaly support CubieTruck Plus in full mode.

just use as a search query "sun8iw6" to find the most relevant patch code for the CubieTruck Plus 5 Board.

Spoiler

HI tkaiser.

Thank you very much for your fast reply and for your engagement to keep the forum focused.

I did searched several times the Forum for 'cubietruck plus' using the forum search functionality but did not find anything related to this board.

Looks like i should have sued the google search instead. thanks for the tip!

I am ready to invest time and a little money to get this board supported.

if somebody has some tips where to start let me know.

i will soon fork the armbian github tree and start adding some stuff for this board.

Step 1 would be to get the newest version of uboot to compile and test it successfull.

HI all.

Why are the Sources for the CubieTruck Plus H8 not included in Armbian?

On GitHub Cubieboard has the Sources for the Board Uploaded.

https://github.com/cubieboard/Cubietruck_Plus-u-boot

https://github.com/cubieboard/Cubietruck_Plus-binaries

https://github.com/cubieboard/Cubietruck_Plus-kernel-source

I have recently buyed a CubieTruck Plus.

Wanted test Armbian on it so i downloaded Armbian and tryed to build a new Image for the Cubie Truck Plus

but could not see anywhere that this board is supported in Armbian despite the fact that sources are available on github.

I gladly would love to help armbian to support this Board in case any help is needed.
