+## How to build the Firmware
+
+1. In a temporary working directory, clone poky the poky repository and check out the dunfell branch:
+```
+	git clone git://git.yoctoproject.org/poky
+	cd poky
+	git checkout dunfell
+	..
+```
+2.  Clone the Renesas BSP and it's dependent layers:
+```
+	git clone https://github.com/renesas-rcar/meta-renesas
+	cd meta-renesas
+	git checkout dunfell-dev-4.14
+	cd ..
+	git clone git://git.openembedded.org/meta-openembedded
+	cd meta-openembedded
+	git checkout dunfell
+	cd ..
+```
+3. Clone the reference hardware BSP layer:
+```
+	git clone https://gerrit.automotivelinux.org/gerrit/AGL/meta-agl-refhw
+```
+4. Create a build environment:
+```
+	. ./poky/oe-init-build-env build
+```
+5. Add the layers to `conf/bblayers.conf`, the `BBLAYERS` variable definition should look like:
+```
+	BBLAYERS ?= " \
+	  /home/user/workdir/poky/meta \
+	  /home/user/workdir/poky/meta-poky \
+	  /home/user/poky/meta-yocto-bsp \
+	  /home/user/workdir/meta-openembedded/meta-oe \
+	  /home/user/workdir/meta-openembedded/meta-python \
+	  /home/user/workdir/meta-renesas/meta-rcar-gen3 \
+	  /home/user/workdir/meta-agl-refhw/meta-agl-refhw-gen3 \
+	  "
+```
+6. Add the machine setting to `conf/local.conf`, for example:
+```
+	echo MACHINE=agl-refhw-h3 >> conf/local.conf
+```
+7. Build the firmware:
+```
+	bitbake arm-trusted-firmware optee-os u-boot
+```
+8. Afterwards, the firmware files will be in the directory `tmp/deploy/images/agl-refhw-h3`.

   You can find these firmwares in the AGL build directory $AGL_TOP/build/tmp/deploy/images/salvator-x
   and you can flash them by using **EM_W** command as following:
