I’ve updated my stable kernel builds to version 4.11. The longterm supported kernel was updated without configuration changes to version 4.4.55. Both kernel branches contain the fix for the latest dirty COW vulnerability.
The kernel builds include the AP1620 WiFi-driver, which needs a binary firmware image you have to download from cubietech’s download server and put it to /lib/firmware/ap6210
New in this 4.11 release:
- enabled Opal Storage support for self-encrypting SSDs
- forced initialization of structured shared with userspace
As usual you may download my kernel builds on this page:
Linux-Kernels for Cubietruck
a lot of my post and guides are updated regularly. The link scheme based on date and post name didn’t work to well for me since all bookmarks to a specific page got lost when updating the posts date. So now I’m using only the name of the post for the permalink. So you’ll find all posts and guides with this naming scheme:
Sorry for the inconvenience and best regards,
Being asked a lot for my newest stable and tested kernels I now decided to put all recent kernels for Cubietruck and compatible devices on its own page. The tarballs provided there contain all needed patches and the kernel configuration to build it on your own, too:
In the kernel 4.0rc5 the maximum clock frequency for all Allwinner A20 based boards was decreased to 960MHz. Certainly, the limitation is not serious, but I see no reason in it, since my Cubietruck runs perfectly stable at 1008MHz, even in warm summer. The following patch restores the maximum frequency again to 1008MHz:

Despite very decent speed my Cubietruck doesn’t perform too well on Android. I bought a Cubietruck as a working PC for my son and I’m almost happy with it – but I hate the small breaks, lags and stuttering in several apps like in the “Maus” app. Another point I really dislike is the shortage of storage memory for apps and data. The major bottleneck is the small and very, very slow NAND memory of the Cubietrucks.
