    Hello,

    To do that, you need to open the script used to create the SD card, "mkmmc-android.sh".
    On lines 73 to 77, each "echo" is used to describe a partition for sfdisk to write, respectively "boot", "rootfs", "usrdata" and "data".

    To change the size, you need to change the number or expression after the first comma. Be careful, they are described as cylinders.
    You can see the first one is 9 for the "boot" partition, which correspond to around 70MB.
    The second and third one, for "rootfs" and "usrdata" partitions take both of them a quarter of your SD card ($CYLINDERS / 4).
    The last one, for "data", as nothing, meaning it will take all the remaining space.
