Android 6.0. How to define partition sizes?

sumanthg — Sat, 09 Sep 2017 12:11:51 GMT

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?

Hi sumanth

one can check sect.5.1.1 Storage partitions attached Android Guide
and look at script mksdcard-android.sh.tar in MfgTools on

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?
