BuildRoot with Nelson Build

[Satya]

In my scenario i would like to use Nelson Build with BuildRoot Filesystem.

Followed the instruction to build kernel & Uboot along with MLO from NELSON post:

       https://eewiki.net/display/linuxonarm/BeagleBone+Black

Stuck to generate systemd within buildroot, as it depends on  external kernel headers.

If using a new buildroot, you can point to the KERNEL directory and start the build. Buildroot will create another directory in the build directory and use rsync the directories.  Also, remove the patch and cop beaglebone_defconfig or the defconfig into the board/beagleboard

I don't have access to my build system at this time; to provide a full set of instructions.  I use Robert's TI linux tree to do this.

Hi michal,

               Thanks for the valuable information. Can you please elaborate over the patch which you are talking about??, i had compiled with beaglebone_defconfig  with instructions provided at:

                             http://www.embarcados.com.br/beaglebone-black-buildroot/

I need to integrate and support the Bluetooth PAN network, with BNEP protocol over my custom board, but seems like i had lot of challenges before i even start over.

Thanks,

pratap

Here are my steps; I'm building the TI kernel..
mkdir demo
cd demo
git clone git://git.buildroot.net/buildroot

From https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-TIBSP

git clone https://github.com/RobertCNelson/ti-linux-kernel-dev/
cd ti-linux-kernel-dev/
git checkout origin/ti-linux-3.14.y -b tmp
./build_kernel.sh
(This should finish with the menuconfig just exit)
cd ../..

You should have the following directories:
buildroot  ti-linux-kernel-dev
mkdir bld
cd bild
make O=$PWD -C ../buildroot/ beaglebone_defconfig
make menuconfig
goto kernel
change Kernel version to Local directory
change path to. the full path to the ti kernel i.e /home/tcmichals/projects/copter/demo/ti-linux-kernel-dev/KERNEL
Then change the configuration path to /home/tcmichals/projects/copter/demo/ti-linux-kernel-dev/patches/defconfig
then save
exit
make
(it is still building.. will take hour or so)
Hope this helps

Woooowww...!!! pheww.....!!! Thank you for your instruction....!!! Look at me..!!! Iam so glad....!!! Thank you so much...!!!

I use the TI kernel because the PRU can be loaded using remoteproc and soon will have the virtio from user space.  

When running the following:

git clone https://github.com/RobertCNelson/ti-linux-kernel-dev/
cd ti-linux-kernel-dev/
git checkout origin/ti-linux-3.14.y -b tmp
./build_kernel.sh
(This should finish with the menuconfig just exit)

after you exit do a control-c, this will stop the compile process. 

The goal is for Roberts scripts to run but not compile. I did not have time to check if there is a way to run them without the compile step.

The path is long and sometimes does not work pasting them in the menuconfig.  Maybe just create a dir in tmp, to make the paths shorter.
