5.5.3.2 Creating a uRamdisk Image

uRamdisk is a tiny kernel image needed to boot uImage from the Disk on Chip.

ng

# /sbin/m

mkdir -p /

mount -o loop ramdisk.image /mnt/ramdisk

Copy everything that is need th mdis disk. Then...

# umount /mnt/ramdisk

# gzip ramdi

Ramdisk can be written t with the docshell utility.

5.5.3.3 Booting from DoC

U-boot, the bootargs

# set bootargs ip=bootp root=/dev/ram0 rw console=ttyMM0,9600n8

ramdisk_siz

# saveenv oot variables to NVRAM

Then boot from disk-on-chip as follows:

docload

# bootm 400000 800000

Alternately, rese

uRamdisk has the same intent as a ramdisk on other linux platforms. It brings up

necessary drivers needed to access the real kernel image (uImage). After booti

the HW400c/2, the following commands will create uRamdisk.

# dd if=/dev/zero of=ramdisk.image bs=1024 count=32768

kfs.ext2 ramdisk.image

# mnt/ramdisk

#

ed in e ra k to /mnt/ram

sk.image

# mkimage -T ramdisk -C gzip -d ramdisk.image.gz uRamdisk

u

o disk-on-chip

In variable should be set as follows:

e=65536

# Save the U-B

#

t the card and let auto boot run.
