Issue in porting Kitkat to iMX6 Board

[sandy123]

Hi Everyone,

When we tried to port Android Kitkat over our custom iMX6-Solo board, we faced several performance issues. For instance, we were not able to run game applications which show CPU usage above 90%. We didnt face these issues while porting Jellybean to our board though it uses the same kernel version as that of kitkat. Is our issues related with GPU?

Hi san,

There is available a BSP of Android KitKat for i.MX6SL, you can find it here: IMX6SL_EVK_KK442_100_ANDROID_DEMO_BSP.

It is good to remember that the SoloLite doesn’t have 3D GPU, and the one included on the Solo (Vivante GC355) is not the same than the one on the Quad/Dual (Vivante GC2000).

So, it could be possible that some characteristics differ between platform and Android version, so, if you have specific GPU requirements, you could try checking the graphics libraries of each version.

Hope this will be useful for you.
Best regards!
/Carlos
