I have downloaded the firmware from
http://downloads.openwrt.org/backfire/10.03.1-rc4/ar71xx/ this link
openwrt-ar71xx-pb44-kernel.bin,openwrt-ar71xx-pb44-rootfs-jffs2.bin these are two files i flashed in the board using fis create command.
The following commands i have used

load -r -v -b 0x80500000 openwrt-ar71xx-generic-pb44-kernel.bin -h 192.168.1.43
fis create -b 0x80500000 -e 0x80064550 -r 0x80060000 -l 0x120000 vmlinux

*

load -r -v -b 0x80500000 openwrt-ar71xx-generic-pb44-rootfs-jffs2.bin -h 192.168.1.43
fis create -b 0x80500000 -e 0x0 -l 0x600000 rootfs

What is your board configuration ?

In my board the flash chip is not detected. From log messages i found its shows as 64K size
flash chip. but it supposed to be 8MB flash chip.

find the attached log message

Could you check if the flash chip on the board is labeled and if yes, post its name? It looks like it gets misidentified.
