You startup assembler file probably expects to be running in Physical
memory. I think iMX25 has SDRAM at 0x80000000 but you have to verify
that. Also verify that the SDRAM is mapped to 0x80000000 in your
Redboot port. If the above is true and 0x180000 is the entry point,
try to start it like this.

lo -r -b 0x180000 nk.nb0
go 0x80180000
