#cp /mnt/cdrom/tools/tool_chain/arm_toolchaintar.bz2 /

#cd /

#tar jxvf arm_toolchaintar.bz2

(Older versions of tar might not accept this, then try using #

tar Ixvf

arm_toolchaintar.bz2

)

Be careful about the root directory of the ARM cross compiler. arm-linux-gcc will invoke cpp0 and cc1 assuming
they reside in certain directories relative to the compiler’s root directory. To be on the safe side, unzip the ARM
tool chain in the root directory /.

Copy the utilities

bin2bin, foxfox, mkfs.jffs2

, padkernel.py

from

tools\utils

directory of

Accelent CD to your execution path (like maybe /bin). These tools are needed to prepare Linux kernel and root
file system for loading into the target.

#cp /mnt/cdrom/tools/utils/* /bin

#cd /bin

#chmod +x bin2bin foxfox mkfs.jffs2

padkernel.py

3.3.2.10.Linux Kernel source

The Linux kernel can be installed in to the PC host from the source code provided by the Accelent CD. Copy the
source code (

linuxtar.bz2

) from Accelent CD to known directory (example

/usr/src

#cd /usr/src

#bzip2 –cd /mnt/cdrom/source/linuxtar.bz2 |tar xfv –

#mv linux-2.4.18-rmk3-pxa2-asi1 /usr/src/linux-otg

Copy the ISP1362 stack related source to the kernel directory (

isp1362_linux_sw_stack.tar.gz).

Apply

the ISP1362 specific kernel patch,

otg_kernel_patch_rev2

from the ISP1362 Linux stack release to kernel

source.

#cd /usr/src/linux-otg
#tar –zxvf isp1362_linux_sw_stack.tar.gz
#patch -p1 <1362/misc/accelent_rev2/otg_kernel_patch_rev2

3.3.2.11.Root File System

Root file system for the IDP is provided in the Accelent CD. Copy the root file system

rootfstar.bz2

to the

/usr/src/linux-otg

directory.

#cp /mnt/cdrom/source/rootfstar.bz2 /usr/src/linux-otg
