Your default/sartup.txt is al wrong. For RAPH800 your mtype should be 2039. Just use this:
Code:
####### Boot Raphael board (also for Diamond devices)
set MTYPE 2039
####### KERNEL
set KERNEL zImage
####### INITRD
set INITRD initrd.gz
####### Size of RAM (continues area)
set RAMSIZE 0x6000000
####### Physical RAM address (override the one set in haret, which seems to fail more often)
set RAMADDR 0x10000000
####### Command line to pass to kernel
set cmdline "root=/dev/ram0 init=/ console=tty0 mem=76M msmsdcc_id=3 zmgdevname=/dev/mmcblk0p1 imgdevnum=1 imgdir=/ msmts_calib=0x81.0x393.0x358.0x7D clock-7x00.a11=500 msmvkeyb_toggle=off"
boot
