Nios II uClinux boot

Hi, Happy New Year to all, there is a good news I successfully generated the vmlinux and vmimage by re-installing some missing libs., but not got full success yet,

one thing that i feel not OK is that the size of vmlinux is 140.1 MB and vmimage is 4.7 MB and the SDRAM on my board is 32 MBytes, does it mean that I will be unable to boot Linux or I have to increase my SDRAM (that will we really very painful task for me, you know!)

OR in the above case can I reduce the size of vmlinux to fit in my SDRAM size, how??

OR can I use other smaller files (less than 32 MBytes) : vmlinux.bin = 10.8 MB, vmlinux.gz = 4.7 MB, vmimage = 4.7 MB to boot linux.

OR generate some other file to boot OR etc.

I am saying this because my nios2-download -g vmlinux command is not working, always the verification fails. (please see the attached images)

I am totally in dark, please help me. thanks
