After gathering information from different resources, here's what I
did using pre-built binaries on SD card:
1) Copy u-boot, mlo, uImage to Boot partition
2) Copy myfs_BR_L27.8.2_CCD/* to root of AFS partition. You get that
from extracting omap4_AFS_L27.8.2.tar.bz2
3) Install Froyo_L27.8.2_Graphics-1.0-Linux-x86-Install to root of AFS
partition
4) Install Froyo_L27.8.2_Ducati_Binaries-1.0-Linux-x86-Install to root
of AFS partition
Use these bootargs to boot:
setenv bootargs 'console=ttyO2,115200n8 root=/dev/mmcblk1p2 rw
rootdelay=2 mem=458M@0x80000000 mem=512M@0xA0000000 init=/init
vram="10M" omapfb.vram="0:4M"'
setenv bootcmd 'mmcinit 0;fatload mmc 0 0x80000000 uImage; bootm
0x80000000'
boot
This works for me, hope it helps.
