HIP:PMP:Kernel

Making Directories

~$ cd /p0/hip/
~$ sudo mkdir archives  (to hold files required to build kernel)
~$ sudo mkdir dev_local (to hold a local copy of the image for building kernel)

Downloading Required Files

Developer CD/Image, Kernel & patch

• Development Kit Project CD Image
• 2.4.23 Kernel
• TS-2.5-2.4.23.patch

Move all files to /p0/hip/archives

Preparing Files

Extract all downloaded files in /p0/hip/archives

• Mount developer image

~$ sudo mount -o loop /p0/hip/archives/ts-dev.img /p0/hip/mnt/

• Create a local copy of the developer image

~$ sudo cp -dpr /p0/hip/mnt/* /p0/hip/dev_local/

• Unmount developer image

~$ sudo umount /p0/hip/mnt/

• Copy and patch kernel

~$ sudo cp -dpr /p0/hip/archives/linux-2.4.23 /p0/hip/dev_local/usr/src/
~$ sudo cp /p0/hip/archives/TS-2.5-2.4.23.patch /p0/hip/dev_local/usr/src/
~$ cd /p0/hip/dev_local/usr/src/
~$ sudo patch -p0 < TS-2.5-2.4.23.patch

If kernel is being patched correctly, you should see something like this...

patching file linux-2.4.23/.config
patching file linux-2.4.23/Documentation/Configure.help
patching file linux-2.4.23/Makefile
....
patching file linux-2.4.23/include/linux/blk.h
patching file linux-2.4.23/include/linux/major.h
patching file linux-2.4.23/include/linux/ts_sbc.h

Building Kernel

First make a directory where modules will be copied into

~$ cd /p0/hip/dev_local/usr/src/
~$ sudo mkdir modules

Then cd into /p0/hip/dev_local/usr/src/linux-2.4.23/

• configuring kernel

~$ sudo make menuconfig

NB: most of the default settings for the TS-5600 would have been set by the patch, so configure the kernel the way you want and save it.

• make dependencies

~$ sudo make dep

• clean directories - remove files from previous builds

~$ sudo make clean

• make bzImage

~$ sudo make bzImage

• make modules

~$ sudo make modules

• install modules

~$ sudo make modules_install INSTALL_MOD_PATH=/p0/hip/dev_local/usr/src/modules/

Copying Built kernel and modules

First load modules and mount the sdcard by following the same steps listed in Backup PMP Then prepare the sdacard and copy the new kernel

• copying bzImage

~$ cd /p0/hip/mnt/sda1/
~$ sudo rm bzImage
~$ sudo cp /p0/hip/dev_local/usr/src/linux-2.4.23/arch/i386/boot/bzImage .

• copying modules

~$ cd /p0/hip/mnt/sda2/
~$ sudo cp -dpr /p0/hip/dev_local/usr/src/modules/lib/modules/* sda2/lib/modules/

Finally unmount the sdcardand unload the modules as listed in Backup PMP
