Yocto BSP build Instructions on AVA Developer Platform

This documentation explains how to quickly get started with the Yocto BSP on AVA Developer Platform.

Build Host Setup

Please refer Yocto Project documentation for the list of essential packages to be installed on the Build Host.

Note: The Build Host machine should have at least 150 GBytes of free disk space for Building the Image.

Minimal Image Build

This section describes how to build images for the Yocto BSP project for the following machines:

The ArmV8.2 Base Ampere Altra machine, corresponding to the com-hpc MACHINE implemented in meta-adlink-ampere

Build Instruction

Checkout the meta-adlink-ampere and dependent repository 

$ mkdir -p ~/ava 
$ cd ~/ava 
$ git clone https://github.com/ADLINK/meta-adlink-ampere.git 
$ git clone https://git.yoctoproject.org/git/poky -b hardknott ./layers
$ git clone https://github.com/openembedded/meta-openembedded.git -b hardknott ./layers
$ git clone https://git.yoctoproject.org/git/meta-security -b hardknott ./layers
$ git clone https://git.yoctoproject.org/git/meta-virtualization -b hardknott ./layers
$ git clone https://git.yoctoproject.org/git/meta-arm -b hardknott ./layers

Build for AVA

$ cd ~/ava
$ TEMPLATECONF=$PWD/meta-adlink-ampere/conf/adlink-conf
$ source layers/poky/oe-init-build-env 
$ bibtake core-image-base

The resulting images will be produced: 

build/tmp/deploy/images/comhpc/core-image-base-comhpc.wic

The above can be boot on AVA Developer Platform and login as root without password.

Prepare Bootable Medium

To install the binaries into USB Drive

Note : Ensure the USB is formatted before proceeding installation

$ sudo dd if=core-image-base-comhpc.wic  of=/dev/sdX bs=1M ( X should be replaced with respect device like sda, sdc or sdd )
For Example: ( USB Device  uses /dev/sda device node )
$ sudo dd if=core-image-base-comhpc.wic  of=/dev/sda bs=1M

To Install the binaries into NVMe M.2 SSD

Please create a USB drive Bootable as mentioned in the above section.

Plug the USB drive (Bootable drive) in Host system, you should see 3 partition mounted namely as below 

</media/<local_directory>/msdos>
</media/<local_directory>rootfs>
</media/<local_directory>/data>

Copy the Images into"</media/<directory>/data>"

$ sudo cp <Yocto_Build_Directory>/build/tmp/deploy/images/comhpc/core-image-base-comhpc.wic.bz2 </media/<directory>/data>
$ sudo cp <Yocto_Build_Directory>/build/tmp/deploy/images/comhpc/core-image-base-comhpc.wic.bmap  </media/<directory>/data>

Insert the USB drive and Boot the Board, login as “root” with NO password via VGA Display and create a “data” Directory

$ cd  /
$ mkdir data

mount the 3rd partition of USB into “data” directory 

$ mount /dev/sda3 /data

Flash the image to the target’s NVMe M.2 SSD drive using bmaptool

$ bmaptool copy --bmap /data/core-image-base-comhpc.wic.bmap /data/core-image-base-comhpc.wic.bz2 /dev/nvme0n1
