Recipes for the Beaglebone Black supporting PRU (RPMsg)

Prepare build machine

sudo apt install build-essential chrpath diffstat gawk libncurses5-dev texinfo git libc6-i386

Clone required repos

git clone -b morty git://git.yoctoproject.org/poky.git poky-morty
cd poky-morty
git clone -b morty git://git.openembedded.org/meta-openembedded
git clone -b morty git://git.yoctoproject.org/meta-ti
git clone -b morty https://github.com/AdrianPeniak/meta-blackbone.git

Environment Setup

source oe-init-build-env

In to use this layer please comment-out default machine "MACHINE ??= "qemux86"" in generated file ./conf/local.conf and add following lines at the end of the file:

-  MACHINE ??= "qemux86"
+  #MACHINE ??= "qemux86"
+  MACHINE = "blackbone-board"
+  DISTRO  = "blackbone-distro"

Optionaly you can choose OPKG (instead of default RPM) packaging systems, for avoid python 2.7 runtime dependencies, by replacing "package_rpm" by "package_ipk":

-  PACKAGE_CLASSES ?= "package_rpm"
+  PACKAGE_CLASSES ?= "package_ipk"

Also plase remove "meta-yocto-bsp" layer from generated file ./conf/bblayers.conf and add following meta layers to the list:

-  <some path>/poky-morty/meta-yocto-bsp \
+  <some path>/poky-morty/meta-ti \
+  <some path>/poky-morty/meta-blackbone \
+  <some path>/poky-morty/meta-openembedded/meta-oe \
+  <some path>/poky-morty/meta-openembedded/meta-python \
+  <some path>/poky-morty/meta-openembedded/meta-networking \

Flash an SD-Card/eMMC for BeagleBone Black

Please use script blackbone-tools.sh in scripts directory and follow script instructions. Run script as sudo:

sudo ./blackbone-tools.sh

For creation SD-Crard for flash eMMC, you have to chose option 2 in script wizard:

Do you want write image for: 
1: SD-Card
2: MMC
2

then put your SD-Card to the SD-Card slot on your BeagleBone and holding the S2 switch down for 5 sec, then the BeagleBone will to try booting from the SD-Card first. The S2 switch is above the SD-Card holder The blackbone-tools script will be automatically launched for the eMMC flashing. When the BeagleBone LEDs stop flashing in cylon-mode, then the eMMC flashing is complete.

Or you can prepare your SD-Card by yourself according this tutorial. And then copy "MLO and u-boot" files to boot partition:

sudo cp MLO u-boot.img /media/<username>/boot/

and write root file system to SD-Card:

sudo dd if=<image name>.ext3 of=/dev/<root fs>
