Android 6.0. How to define partition sizes?

[sumanthg]

In android, we have /system /cache /misc /userdata partition. In the Boardconfig.mk file we can define the specific partition sizes for this android 

But, After flashing the android images to the imx6dl device. 

the system partition was not created correctly?

For example: 

system partition size = 576.6 MB but in boardconfig.mk file it was defined as 600MB why?

In MFG tool the system size is defined as 800MB but in Android Guide it was defined as 512MB Why is difference

And one more doubt, if i change cache size in mksdcard-android.sh.tar file to 800MB and  I didn't change the size of cache partition in the source code "/device/fsl/im6/boardcommonconfig.mk". And i flashed the android images to the imx6dp processor.

After the android booted up. i look up in the *df* command it should cache parition size is "771.4MB" 

1. why this happens like this?

                           MFG tool             android source code                  After the device boot up through *df* cmd it shows

cache partition    800MB                 424MB                                        771.4MB

2.if, i what to change the /cache partition in android source code. what is the location?
