A meta-layer to build a sip based doorphone

Currently used in a build-farm for the following boards

• Raspberry Pi, all flavors, but most testing on RPi4, RPi3 and RPi0-W

This layer depends on:

URI: git://git.yoctoproject.org/poky.git
branch: dunfell 

URI: git://git.openembedded.org/meta-openembedded
branch: dunfell 

URI: git://git.yoctoproject.org/meta-security.git
branch: dunfell 

meta-tro layer maintainer: Thomas Roos thomas@roosesweb.de

steps to get started for me (borrored from: https://jumpnowtek.com/rpi/Raspberry-Pi-4-64bit-Systems-with-Yocto.html):

bitbake console:

bitbake console-image

different console:

sudo su

export MACHINE=raspberrypi4-64

export OETMP=/home/tro/yocto/build/tmp


once: cd /home/tro/yocto/poky/meta-rpi64/scripts/ 
	 sudo ./mk2parts.sh sde
      sudo mkdir /media/card

/home/tro/yocto/poky/meta-rpi64/scripts/copy_boot.sh sde

/home/tro/yocto/poky/meta-rpi64/scripts/copy_rootfs.sh sde console

work:

root pwd: toor

/boot partition edit config.txt start_x=1 disable_camera_led=1

misc notepad:
