I am starting with fastmodel and getting Android booting on it .I am currently using RTSM_VE for A15 to start with and NFS filesystem. UART is simulated as ttyAMA0 and logs could be captured through it. The plan is to support A9, A15 and A15 + A7 combinations.
Hello,
Sorry if I am late to chime in, but Virtual Open Systems has already done some work regarding Android on A15 FastModels. You can find a proof of concept guide/tutorial on our homepage http://www.virtualopensystems.com/.
As a base kernel we use the latest kvm-a15-v6 branchhttps://github.com/virtualopensystems/linux-kvm-arm, together with the attached Android patch set and kernel configuration.
Most things seem to work, although performance is far from perfect, as any rendering to the framebuffer can slow things to a drag. Also, for the time being sound doesn't work and there is no USB for Fast Models (no USB storage and some applications depend on it). Booting seems to be working for both NFS and MMC (less that 2GB image) but MMC seems to be a bit faster in my experience (although NFS is more convenient). Logcat still complains about various stuff and I guess that a lot of things could be improved.
For the Android userland you should use this set of patcheshttp://linux-arm.org/git?p=armdroid.git;a=commit;h=58fb51bf42b867b6f3639fbaa74beba114f03fb5against AOSP. If not, SystemUI will always nag you with an exception pop up and Wallpapers and Gallery won't work. Alternatively you can just run "pm disable com.android.systemui" and the nagging pop up will vanish but wallpaper rendering still won't work. I've already tried successfully the Linaro Android Images for Versatile Express and they are working, but the mentioned SystemUI exception still remains.
If you need further details please let me know.
Sincerely, Alexander Spyridakis.
