Hi Pengfei,
Please refer the device tree: we reserve just 2GB out of 8GB
Please modify based on your customization.

Hi Suren Porwar
I have already modify linux Memory is 1GB
I set bootargs ="console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait mem=1G"
there is the linux kernel log
