Thank you for help, :)

How have you partitioned the 4GB card ?

There are two partitions on SD card.

root at embd ~$cat /proc/partitions
major minor #blocks      name

 179     0      3872256     mmcblk0
 179     1      3868160     mmcblk0p1

I copied u-boot and uImage on first partition (mmcblk0),
and rootFS on second partition (mmcblk0p1).

Any reason why /tmp and /var are 512KB ?

I used 'ltib'  utility to  create all the images and rootFS.
I just follow the instruction from manual given by board vender.
I have one question,
Who allocate a 512KB size for /tmp ?
Where do I search it ?

I do not crate a separate partition for /tmp and /var, they are as a folders
on root partition,
Will you please guide me how to create a tmpfs partition for /tmp ?
and What is the size of it?

Here is output of mount command,

root at embd ~$   mount
rootfs on / type rootfs (rw)
/dev/root on / type ext3
proc on /proc type proc (rw,relatime)
sys on /sys type sysfs (rw,relatime)
tmpfs on /dev type tmpfs (rw,relatime,mode=755)
devpts on /dev/pts type devpts (rw,relatime,gid=5,mode=620)
shm on /dev/shm type tmpfs (rw,relatime)
rwfs on /mnt/rwfs type tmpfs (rw,relatime,size=512k)
rwfs on /tmp type tmpfs (rw,relatime,size=512k)
rwfs on /var type tmpfs (rw,relatime,size=512k)
