Kernel compilation 3.8.3

# NAS Status: Booted into debian, buffalo kernel
# Goal: Real kernel with brains!
# Everything below as root, make sure we are in ~/
# ---
# Thanks hato! He put the patch file together, and created the .config file for you to build on
# Special credits go to Phil Sutter (TDMA support for CESA engine) - included in the patch
# ---
# NOTE:
# Quote hato:
#    "Please remember to warn the audience the kernel configuration still uses
#    built-in (default) kernel command line, if you haven't change that setting."
#
# under "BOOT OPTIONS", line 403:
#    CONFIG_CMDLINE="loglevel=7 root=/dev/sda2 rw initrd=0x00800040,12M
#    netconsole=6665@192.168.1.2/eth0,6666@192.168.1.24/00:1e:c2:be:47:18"
# If you don't know what this means, ignore this and continue below
# ---
# NOTE2:
# After kernel compilation, do NOT INSTALL BSTOOLS! This WILL brick your NAS, and you
# have to start over with TFTP

# As of 2013-03-21, I have no idea how to get the powerswitch  to work.
# If you wish to shutdown the NAS with this kernel (and .config and patch):
# Put powerswitch on back of NAS to 'OFF'
# Login as root
# reboot
# This will power down the NAS.

apt-get update
apt-get install build-essential fakeroot uboot-mkimage debhelper python libncurses5-dev screen

screen          # Press space or enter to continue
# We are now using screen. This utility gives us some advantages. Everything we do inside this 'screen'
# will be saved, even if we loose connection between you and the host (in this case the NAS).
# Also, the compiling takes a long time. With this tool, we can detach the console and close our ssh
# client.
# To detach: press CTRL + A, followed by CTRL + D. To re-attach the screen, enter 'screen -r'

# We need to download two files. First the config file
wget http://http://members.ziggo.nl/roodgoudzilver/lswvl/kernel/lswvl_config_by_hato.config

# Now we have to download the patch. There are two different patches. One for devices with NAND, and one
# for devices without NAND. If you bought your NAS with drives, you do NOT have NAND. If you bought
# your NAS without drives, you DO have NAND. Download and apply only ONE patch.
# With NAND
wget http://http://members.ziggo.nl/roodgoudzilver/lswvl/kernel/lswvl_support_and_mv-cesa_dma_3.8_nand_native.patch
# Without NAND
wget http://http://members.ziggo.nl/roodgoudzilver/lswvl/kernel/lswvl_support_and_mv-cesa_dma_3.8_nonand_native.patch

# If you are cross compiling, you can download these patches:
# With NAND
wget http://http://members.ziggo.nl/roodgoudzilver/lswvl/kernel/lswvl_support_and_mv-cesa_dma_3.8_nand_cross.patch
# Without NAND
wget http://http://members.ziggo.nl/roodgoudzilver/lswvl/kernel/lswvl_support_and_mv-cesa_dma_3.8_nonand_cross.patch

cd /usr/src
wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.8.3.tar.bz2
tar xjf linux-3.8.3.tar.bz2

patch -Np1 --dry-run -i ~/lswvl_support_and_mv-cesa_dma_3.8*.patch      # Dry-run the patch. No errors?
                                        # Continue!

patch -Np1 -i ~/lswvl_support_and_mv-cesa_dma_3.8*.patch            # Apply the patch

cp ~/lswvl_config_by_hato.config ./.config

# The .config has netconsole enabled. Google it, it's very useful.
# Edit the .config file, go to line 403.
# Change the following:
# 192.168.1.2       - IP of the NAS
# 192.168.1.24      - IP of the target machine (who is displaying the bootlog)
# 00:1e:c2:be:47:18 - Mac address of the ethernet card of the target machine
nano .config
# Save and quit

# If you want to alter the kernel (You can try this config first, if it works you can recompile the kernel
#                  with this guide and make modifications with menuconfig. This way you know
#                  where it went wrong if it's not working)
make menuconfig

# Compile the kernel
make uImage modules                 # This will take a LONG time
cp arch/arm/boot/uImage uImage.buffalo.debian       # This is very quick
make modules_install INSTALL_MOD_PATH=./modules     # This is quick

# Install kernel
mount -o remount,rw /boot               # Remount /boot as readwrite

mv /boot/uImage.buffalo /boot/uImage.buffalo.old    # Make backup of stock kernel
cp uImage.buffalo.debian /boot/uImage.buffalo       # Copy kernel

# Copy modules
cp -a modules/lib/modules/3.8.3 /lib/modules

# Now the kernel is installed. As stated before, the kernel supports netconsole. Start
# a netcat client on the target computer. Depending on your client you either have to start
# it with:
# nc -u -l 6666
# or
# nc -u -l -p 6666

reboot                          # AND PRAY!

# As soon as the blinking light on the NAS goes solid, you should see a bootlog coming up on
# your netcat. If it doesn't show any (significant) errors, you should be good to go.
# Here is an example bootlog of a succesfull boot: http://pastebin.com/0wNJn1vB

# Try to ssh to your NAS and see if it works. If you can login, check
uname -all
# to see if you are running a 3.8.3 kernel
