Everything that applies to Banana Pi M3 also applies to the Cubietruck Plus (except DC-IN -- Cubietech uses not the moronic Micro USB connector but a sane power barrel). With these devices you get:

  • great theoretical integer performance (you won't be able to benefit from unless you use heatsink and a fan)
  • worst I/O bandwidth possible due to crappy GL830 USB-to-SATA bridge (but Cubietech wasn't that moronic as 'Team BPi' and used one USB host port for GL830 and used the other for an internal USB hub -- on Banana Pi M3 only 1 USB host port is used and everything is behind the internal USB hub)
  • If you're able to apply the fixes from the Banana people you could make use of GPU acceleration (please keep in mind that H8/A83T/R58 rely on a pretty slow SGX544MP1 GPU)

For many use cases the Cubietruck Plus is a real downgrade compared to the older Cubietruck (H8 vs. A20).

 

BTW: The pcDuino8 Uno is also based on H8 but doesn't waste an USB port for a crappy USB-to-SATA bridge. Unfortunately the LinkSprite people don't understand the GPL, do not release their BSP variant and their users are even more lost than unfortunate Banana Pi M3 customers.

Apologies, I'm a bit new to this.  Managed to do a build for my banana pi using the slick build scripts.  Looking to see what options I have now for this cubietruck5 I have here.  You mentioned it is comparable to the m3 build but I'm not seeing an option for that in the build script.  Should I choose the bananapi m2 build and start from there?    I have a semi working Linaro build but I'd prefer to go with a minimal debian based build and add what I need from there.  

 

Thanks!

M3 is very different than M2.

 

As you can see here, 

http://linux-sunxi.org/Linux_mainlining_effort

there won't be alternative kernel any time soon.

 

Unfortunately you are stuck with buggy Android kernel based stock distribution, where you won't get much support or updates. If you plan to operate any serious stuff, get A20 based board and put this board away for at least 6 months.

I jumped in without doing my research.  I'll go do my homework on A20 based options and find something more immediately suitable for my task.  Thanks!

Hi all,

 

Is there any armbian that runs on cubieboard 5?

 

Thanks

 

Official? No. We would need to invest lots of time into legacy kernel cleaning, hacking, adjusting, ... There is also no proper mainline u-boot support.

 

Banana M3 and Cubietruck 5 has similar design and some basic support exists in U-boot and mainline kernel. Recently I made a test with M3 and was up with IIRC single core, usb, sata, serial console only. I suspect Cubietruck 5 can reach the same level. Wens is working on those two to bring them into mainline kernel, but it's (slow) WIP. I figured out that one nasty patch needed to be applied to u-boot, that we got all cores working. At least server usage could soon become possible from that stage.

Hi Igor,

 

Thanks for the answer. I was going to buy the cubietruck plus but I'm going to buy the cubietruck (cb3) that is already 100% :)

 

Congratulations to all for the excellent work done!
