• Partition 4GB Compact Flash card

Let's try to boot Linux directly from WinCE using HaRET bootloader. In order to do that, create two fdisk partitions on CF card. The first one with FAT filesystem containing HaRET bootloader along with its configuration file and Linux kernel. The second one is formatted as ext2 and will contain Linux root filesystem.

# fdisk -l /dev/sdd

Disk /dev/sdd: 3997 MB, 3997163520 bytes
123 heads, 62 sectors/track, 1023 cylinders, total 7806960 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00006d65

   Device Boot      Start         End      Blocks   Id  System
/dev/sdd1            2048       67583       32768    6  FAT16
/dev/sdd2           67584     7804927     3868672   83  Linux
#

• Populate FAT partition with HaRET and Linux kernel

# mkdir /tmp/fat16
# mount /dev/sdd1 /tmp/fat16
# wget http://pda-linux.googlecode.com/files/haret-0.5.2.exe -O /tmp/fat16/haret-0.5.2.exe
# echo 'set kernel "zImage-2.6.21-hh20-r26-hx4700.bin"' > /tmp/fat16/startup.txt
# echo 'set cmdline "root=/dev/hda2 rootdelay=10 console=ttyS0,115200n8 console=tty0 psplash=false"' >> /tmp/fat16/startup.txt
# echo 'bootlinux' >> /tmp/fat16/startup.txt
# cp ${PROJECT_DIR}/setup-scripts/build/tmp-angstrom_2008_1/deploy/glibc/images/hx4700/zImage-2.6.21-hh20-r26-hx4700.bin /tmp/fat16/
# sync
# umount /tmp/fat16

• Populate ext2 partition with root filesystem

# mkdir /tmp/ext2
# mount /dev/sdd2 /tmp/ext2
# cd /tmp/ext2
# tar xvjpf ${PROJECT_DIR}/setup-scripts/build/tmp-angstrom_2008_1/deploy/glibc/images/hx4700/Angstrom-x11-gpe-image-glibc-ipk-2011.03-hx4700.rootfs.tar.bz2
# cd ~
# sync
# umount /tmp/ext2

• Boot Linux by executing haret binary from WinCE
