-===== How to build the Kernel only =====
+===== How to build the latest CIP Kernel for iwg20m =====
-TODO
-===== How to build the full iwg20m BSP from Renesas =====
+The Renesas RZ/G1M iWave Qseven development kit (iwg20m) is supported in the [[https://gitlab.com/cip-project/cip-kernel/linux-cip|CIP SLTS Kernel]]. The instructions below describe how to build the CIP SLTS Kernel for the iwg20m platform using the Renesas RZ/G toolchain.
+==== Build Steps ====
+. Checkout CIP Kernel
+<code>
+$  cd [your working directory]
+$  git clone git://git.kernel.org/pub/scm/linux/kernel/git/bwh/linux-cip.git
+$  cd linux-cip
+$  git fetch origin  # Not needed if a fresh clone
+$  git checkout origin/linux-4.4.y-cip
+</code>
+. Configure compiler environment
+If using the [[civilinfrastructureplatform:cipreferencehardware:iwg20m:iwg20mbuildinstructions#how-to-builduse-the-sdk|Renesas SDK]]:
+<code>
+$  source /opt/poky/2.0.1/environment-setup-cortexa15hf-vfp-neon-poky-linux-gnueabi
+$  unset LDFLAGS
+</code>
+. Configure uImage load address
+<code>
+$  export LOADADDR="0x40008000"
+</code>
+. Configure Linux config for iwg20m platform
+<code>
+$  make shmobile_defconfig
+</code>
+. Build the Kernel and device tree
+<code>
+$  make uImage
+$  make dtbs
+</code>
+==== Build Output ====
+Output file locations:\\
+- Kernel: arch/arm/boot/uImage\\
+- Device tree: arch/arm/boot/dts/r8a7743-iwg20d-q7.dtb\\
+- Device tree: arch/arm/boot/dts/r8a7743-iwg20d-q7-dbcm-ca.dtb (when using camera/HDMI add-on board)

 ===== How to build/use the SDK =====
-TODO
+This section contains information on how to build and use the Renesas RZ/G SDK.
+Full instructions can be found in section 5 of the "Yocto Start-Up Guide" that can be downloaded from the Renesas RZ/G Marketplace:\\
+https://mp.renesas.com/en-eu/rzg/marketplace/document/R01US0227EJ.html
+==== Build Steps ====
+. Follow the BSP build instructions above, steps 1-6
+It doesn't matter if step 7 has already been run or not.
+. Configure host PC architecture
+It is possible to build the SDK to run on a host PC using a different environment to the PC building the SDK.
+In $WORK/build/conf/local.conf:
+<code>
+# This variable specified the architecture to build SDK/ADT items for and means
+# you can build the SDK packages for architectures other than the machine you are
+# running the build on (i.e. building i686 packages on an x86_64 host.)
+# Supported values are i686 and x86_64
+#SDKMACHINE ?= "x86_64"
+SDKMACHINE ?= "i686"
+</code>
+. Build SDK with bitbake
+<code>
+$  cd $WORK/build
+$  bitbake core-image-weston-sdk -c populate_sdk
+</code>
+==== Build Output ====
+Once the build is completed, the toolchain will be located in the $WORK/build/tmp/deploy/sdk/ directory (poky-glibc-[x86_64|i686]-core-image-weston-sdkcortexa15hf-vfp-neon-toolchain-2.0.1.sh).
+==== Using the SDK ====
+. Install the toolchain on host PC
+<code>
+$  sudo poky-glibc-[x86_64|i686]-core-image-weston-sdk-cortexa15hf-vfp-neon-toolchain-2.0.1.sh
+[sudo] password for (INSTALL person): [enter password of your account]
+Enter target directory for SDK (default: /opt/poky/2.0.1): [enter new location or just key enter]
+Extracting SDK...done
+Setting it up...done
+SDK has been successfully set up and is ready to be used.
+</code>
+. Set up environment variables for build
+<code>
+$  cd [your working directory]
+$  source /opt/poky/2.0.1/environment-setup-cortexa15hf-vfp-neon-poky-linux-gnueabi
+#  When you use “ld” directly but not via gcc (in case of building Kernel, Driver or u-boot), disable LDFLAGS:
+$  unset LDFLAGS
+</code>
+. Build application
+<code>
+$  $CC [your source code].c [optional FLAGs etc.]
+</code>
