5 years ago Good question.
In order to use these drivers, you might need to apply the latest Mali GPL Kernel driver. https://developer.arm.com/products/software/mali-drivers/midgard-kernel
Here's a modified version of my main script, that does the job :

Just press Enter to configure the new Mali configuration options and then you'll have your kernel stuff in /tmp/RockMyy-Build/{boot,lib,usr} with boot containing the kernel image and DTB files, lib the modules and usr the user-space headers used by some applications.
The modules will include the Mali kernel driver r28p0. Give it a try and tell me how it fares.
How you install them on your system depends on your system (I got no Chromebook to test this on).
Note that the script works as a standalone script. Meaning that you can just save it somewhere, run it on a machine with Internet access available and it will do its own thing.
That said, while RK3288 chips are similar, Armbian developers got some issues with Mali drivers working on some specific RK3288 and not others (e.g. It worked on Asus Tinkerboard but not on some MQMaker MiQi devices, ...).
Still, that would be awesome if that worked.

I noticed that my Chromebit has
libmali.so->1.4 Midgard-"r22p0-01rel0". Since it has RK3288, the same as Asus TinkerBoard. Could i reuse it's libs to get hardware acceleration working on the tinkerboard?(i've tried Armbian images, TinkerOS v2.0.7-8 and i never get chrome with video hardware acc working).
My attempt was:
libmali.sofrom Chromebit and place it to/home/linaro/mali_testin TinkerBoardLD_LIBRARY_PATH=/home/linaro/mali_test /etc/chromeOutput:
file /dev/mali0 is not of a compatible version (user 11.4, kernel 10.6)What else should i grab to make it work? Or can i bypass that compatibility check to see if it works anyway?
I could share the libs if they fit for your project too. I've also seen that they have
rk3288_vpumodule rather thanrockchip_vpu.
