When I want to boot Neo FreeRunner from SD card, do I have to follow the
steps like: http://wiki.openmoko.org/wiki/Booting_from_SD? Or is there
any easy method to boot from SD? Like just copy the files needed into SD
card and select Boot from SD card from Boot Menu. Thanks!!
Following is my step for foot from sd function, using ubuntu and clean
512 MB Sandisk microSD card (original FAT16 partition SD card):
*Step 1, umount volume:
sudo umount /media/disk-1
Then re-partition the sd card into 2 partition, first one using vfat and
have 8MB size for uImage.bin, second(rest of storage) using ext2 format
for rootfs files/directory. Both volume using primary partition type.
*Step 2, fdisk:
sudo fdisk /dev/mmcblk0

====================
*Step 3 Format:
Format 2 volume with vfat (uImage.bin) and ext2 (rootfs files)
mkfs -t vfat /dev/mmcblk0p1
mkfs -t ext2 /dev/mmcblk0p2
*Step 4 Copy files into 2 volume:
sudo cp -r /home/tony/Desktop/kernel/uImage.bin /media/disk-1
sudo cp -r /home/tony/Desktop/root_files/. /media/disk-2
sync
*Step 5 Select the boot from SD from menu (with correct u-boot_env content)
