1	sudo apt-get install gawk wget git-core diffstat unzip texinfo  gcc-multilib build-essential chrpath socat cpio python python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping libsdl1.2-dev xterm
	 git clone git://git.yoctoproject.org/poky -b dunfell
	 git clone git://git.yoctoproject.org/meta-raspberrypi -b dunfell
	 git clone https://github.com/openembedded/meta-openembedded.git -b dunfell
2	Now open local.conf 
	open ==> poky/build/conf/local.conf
	Update: 
	MACHINE ?= "raspberrypi4"

3	Create layer:
	inside ==> poky/build $ create-layers ../meta-errorlogger

4	Adding layer:
	inside ==> poky/build $ add-layers ../meta-errorlogger

5	Adding Recipes:
	1. errorserver
	inside ==> /poky/meta-errorlogger/recipe-errorserver/errorserver/files
	Paste the source files.
	inside ==> /poky/meta-errorlogger/recipe-errorserver/errorserver
	Run vi errorserve_0.1.bb
	Now modify to run the command do_compile and do_install the errorserver 
	2. displayserver
	inside ==> /poky/meta-errorlogger/recipe-errorserver/errorserver/files
	Paste the source files.
	inside ==> /poky/meta-errorlogger/recipe-errorserver/errorserver
	Run vi errorserve_0.1.bb
	Now modify to run the command do_compile and do_install the errorserver 
6	inside => poky/build
	Install Recipes using :
	1. bitbake errorserver
	2. bitbake displayserver
7	Now Run bitbake core-image-sato to create the image for raspberrypi 

8	Now go to poky/build/tmp/deploy/images/raspberrypi/ 
	search for core-image-sato.wic.bzip2 file
9	Unzip the core-image-sato.wic.bzip2 
	using command : bzip2 -f -d core-image-sato.wic.bzip2
10	Now search for core-image-sato image using ls -l | grep core* 

11	Now insert the microSD  card reader on the Linux command:
	get the directory of sd card: dev/sdb [default]
12	Now using dd command inside poky/build/tmp/deploy/images/raspberrypi/ 
	dd -f poky/build/tmp/deploy/images/raspberrypi/core-image-sato.wic dev/sdb status=progress
13	Now insert the microSD card on raspberrypi board and boot it.
