hey thnx,
             Actually that problem is solved u r absolutely right ....i did mkimage and its working fine....but i am not able to see the linux prompt...
 Actually i am using Phytec board with LPC2294 ARM7TDMI. and i am using the following pachakes:
 Even i am able to write the kernel and romfs image using 'loadb' command of u-boot. but not getting prompt when i use 'bootm'.
 As there is no support for this board and CPU , iadded those in u-boot. 
 a bit out of track Question : Actually i am getting error : undrfineed reference to machine_lookup_type , somehow i am ablr to solve it by copying arch/arm/kernel/head-common.S to arch/arm/mach-lpc22xx/. and incude head-common.S at end in head.S.
 So is that right? if not what can be the wring thing i am doing ? i wanna boot uClinux on Phytec board. 
 Please help me out.
 Thanks and Regards,

  Make sure that you have used the 'mkimage' tool to encapsulate
  a compressed or uncompressed Linux kernel image with header
  information, checksum etc. See the README file in your U-Boot
  distribution for details. e.g. for ARM Integrator platforms:

  mkimage -A arm -O linux -T kernel -C none -a 0x7fc0 -e 0x8000
          -n 'ARM Linux 2.6.x' -d linux-2.6.x.bin linux-2.6.x.img


Talk is cheap. Use Yahoo! Messenger to make PC-to-Phone calls.  Great rates starting at 1&cent;/min.
