meta-xilinx-tools is a new layer available from the v2016.3 release.




This layer depends on Xilinx SDK to be installed. Please download the SDK from
https://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/embedded-design-tools.html

This layer depends on XSCT being installed in the path. XSCT path has to be defined in local.conf
XILINX_SDK_TOOLCHAIN = "<path to installed XSCT>"
XILINX_VER_MAIN = "<release-version>"

release-version can be 2016.3, 2017.1 etc

meta-xilinx-tools recipes depends on HDF to provided,
HDF_BASE can be set to git: or file:
HDF_PATH will be git repository or the path containing HDF

Ex:
HDF_BASE = "file://"
HDF_PATH = "<path-to-HDF-in-local-directory>"                 // ex: HDF_PATH = "/home/user/system.hdf"
 
 
HDF_BASE = "git://"
HDF_PATH = "<path-to-HDF-in-git>"                            //ex: HDF_PATH = "github.com/hdf-base.git"

Using the layer

The layer can be used via dependencies while creating the required Boot.bin.
Basically the goal to build FSBL or PMU etc will depend on the use-case and Boot.bin will indicate these dependencies.

Boot.bin is created using bootgen tool from Xilinx. Please refer to help files of bootgen.
Executing bootgen -bif_help will provide some detailed help on BIF attributes.

BIF file is required for generating Boot.bin, BIF is partitioned into Common BIF attributes and Partition BIF attributes.
Attributes of BIF need to be specified in local.conf while using xilinx-bootbin.bbclass for generating Boot.bin

2017.1 release or above BOOT.BIN creation:

Once the HDF is provided using above mechanism (HDF_BASE and HDF_PATH) , meta-xilinx-tools will build boot.bin based on the below config

https://github.com/Xilinx/meta-xilinx-tools/blob/master/conf/machine/include/machine-xilinx-zynqmp.inc
https://github.com/Xilinx/meta-xilinx-tools/blob/master/conf/machine/include/machine-xilinx-zynq.inc

The above can be tuned in local.conf to include or remove things in boot.bin


Example ZU+ zcu102 Boot.bin BIF setup is provided (add these in local.conf for release 2016.4 or below):

Example Zynq-7000 zc702 Boot.bin BIF setup is provided (add these in local.conf for release 2016.4 or below):

|| #add Boot.bin dependencyIMAGE_CLASSES += " xilinx-bootbin"#specify BIF partition attributes required for BOOT.binBIF_PARTITION_ATTR= "fsbl u-boot"

NOTE:
Please install xvfb package on host ( this is an xsct requirement)
