You can change the following to increase the system image size:

/device/rockchip/rk3328/BoardConfig.mk
BOARD_SYSTEMIMAGE_PARTITION_SIZE := 2147483648

//This is for 2GB size, you can change it to anything that still fits on the EMMC or SDCard.

You must also increase the system.img size in the parameter file so the firmware can boot.
Start by increasing the offset before @system and then adjust all the partition offsets after that too.
This should be for 2GB system partition.

0x00400000@0x000B2000(system)
before @ is the size, after @ is the location.
0x00400000 in hex is 4194304 decimal * 512 / 1024 / 1024 = 2048MB(2GB)
0x000B2000(old location) + 0x00400000(size) = 0x004B2000 (The same as the new location of metadata)
So adjust al the locations of partitions metadata, baseparameter, userdata after system too.
