Hi, This is because 4.x is much more demanding of the GPU, but we currently don't have a working GPU driver for I.MX53, so all the work ends up being done by the CPU. The fix is getting a GPU driver (try looking in Freescale's BSP releases - the driver is thete, but seems to rely on patches we still need to identify) On Jun 18, 2012 3:52 PM, "Swaraj" swaraj.vutturi@redpinesignals.com wrote:

Hi All,

The performance is very slow when i updated android from 2.3 to 4.0.4 on iMX53. Cursor movement is very very slow while unlocking. How should i improve performance on IMX53 with android 4.0.4.

Thanks & Regards, Swaraj
