Wrong Image Format for bootm command

as you see i loaded the image into address 0x32000000 
but cant boot the kernel.
the file is C0A90A14.img zImage_T35  which works from supervivi>boot
command.

any ideas please?

solved-
intsall uboot-mkimage
and run mkimage -A arm -O linux -T kernel -C none -a 0x30008000 -e
0x30008000 -d ./zImage_T35 ./uImage

what is the exact memory address to load the zImage and u-boot.bin through
tftpboot?

You can use address 0x30000000.

But you cannot load zImage via u-boot. Well, maybe you can but it won't
boot. Convert zImage to uImage first just like ymymymym did.
