HI Everybody,

I need to stay on "older" Android JB 4.3 due to my application .

I must move kernel from 4.3 to 4.4 due to mounting bigger DDR 4GB now , so a newer kernel .

I m having issues on SGX driver integration : is there any suggestion ? any compatibility issue to solve ?

best regards

HI Everybody ,

let me correct /add some data::

I need to stay on "older" Android JB 4.3 due to my application . I must move kernel from 3.8 to 4.4 due to mounting bigger DDR 4GB now , so a newer kernel .

Is it possible to run Android JB 4.3 over Kernel 4.4 , is there some limitation we need to take in consideration especially for the PVR / SGX drivers ?

thank you

best regards

Carlo

Hi Carlo,

Below link shows supported Android version and Kernel version combination.
https://processors.wiki.ti.com/index.php/Processor_SDK_Android_Automotive

Moving JellyBean Android SDK version from Kernel 3.8 to Kernel 4.4 is not feasible.
Jellybean code base is almost 7 years old and some of the components used in JB (like Graphics DDK) is no longer supported. Let's take this offline.

Vishal
