This layer provides support for using Xilinx tools on supported architectures MicroBlaze, Zynq and ZynqMP.

Please send any patches, pull requests, comments or questions for this layer to the meta-xilinx mailing list with ['meta-xilinx-tools'] in the subject:

This layer depends on:

• **If you don't have "x11" in your DISTRO_FEATURES, you'll need xlsclients and Xvfb to satisfy the SDK's dependence on it. You may install these by apt-get install -y xvfb x11-utils or the like. Note that if your system distro doesn't install those in /usr/bin, you'll need to provide links for them in /usr/bin since xsct (from the SDK itself) not only depends on these but it actually assumes /usr/bin.

• XSCT being installed somewhere the yocto build can access. You must define this path by specifying the XILINX_SDK_TOOLCHAIN variable globally, typically in your local.conf (or site.conf).

The supported tool version is indicated in XILINX_VER_MAIN which defaults to the current release that is checked out.

It would be wise then to define XILINX_SDK_TOOLCHAIN like so: XILINX_SDK_TOOLCHAIN = "/full/path/to/xilinx/SDK/${XILINX_VER_MAIN}"

Each release is dependent on the Xilinx XSCT release version. Please note that xsct tools may not be backward compatible with embeddedsw repo. Meaning 2016.3 xsct tools might not work with older version on embeddedsw repo

meta-xilinx-tools recipes depends on HDF to be provided.

HDF_BASE can be set to git:https:// or file:https://

HDF_PATH will be git repository or the path containing HDF

This 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

1. Example to include dependency for zc702-zynq7 board

IMAGE_CLASSES += " xilinx-bootbin"

BIF_PARTITION_ATTR= "fsbl u-boot"

BIF_PARTITION_IMAGE[fsbl]="${DEPLOY_DIR_IMAGE}/fsbl-${MACHINE}.elf" BIF_PARTITION_DEPENDS[fsbl]="virtual/fsbl"

BIF_PARTITION_IMAGE[u-boot]="${DEPLOY_DIR_IMAGE}/u-boot-${MACHINE}.elf"

2. Example to include dependency for zcu102-zynqmp board

IMAGE_CLASSES += " xilinx-bootbin"

BIF_COMMON_ATTR= "fsbl_config" BIF_COMMON_ATTR[fsbl_config]="a53_x64"

BIF_PARTITION_ATTR= "fsbl pmu atf u-boot"

BIF_PARTITION_ATTR[fsbl]="bootloader" BIF_PARTITION_IMAGE[fsbl]="${DEPLOY_DIR_IMAGE}/fsbl-${MACHINE}.elf" BIF_PARTITION_DEPENDS[fsbl]="virtual/fsbl"

BIF_PARTITION_ATTR[pmu]="destination_cpu=pmu" BIF_PARTITION_IMAGE[pmu]="${DEPLOY_DIR_IMAGE}/pmu-${MACHINE}.elf" BIF_PARTITION_DEPENDS[pmu]="virtual/pmufw"

BIF_PARTITION_ATTR[atf]="destination_cpu=a53-0,exception_level=el-3,trustzone" BIF_PARTITION_IMAGE[atf]="${DEPLOY_DIR_IMAGE}/arm-trusted-firmware-${TUNE_PKGARCH}.elf"

BIF_PARTITION_ATTR[u-boot]="destination_cpu=a53-0,exception_level=el-2" BIF_PARTITION_IMAGE[u-boot]="${DEPLOY_DIR_IMAGE}/u-boot-${MACHINE}.elf"

This layer provides additional configurations through YAML

1. Example YAML based configuration for uart0 setting in PMU Firmware

YAML_FILE_PATH = "${WORKDIR}/pmufw.yaml" YAML_BSP_CONFIG="stdin stdout" YAML_BSP_CONFIG[stdin]="set,psu_uart_0" YAML_BSP_CONFIG[stdout]="set,psu_uart_0" XSCTH_MISC = "-yamlconf ${YAML_FILE_PATH}"

2. Example YAML based configuration for device tree generation

YAML_FILE_PATH = "${WORKDIR}/dtgen.yaml" YAML_BSP_CONFIG="main_memory console_device pcw_dts" YAML_BSP_CONFIG[main_memory]="set,psu_ddr_0" YAML_BSP_CONFIG[console_device]="set,psu_uart_0" YAML_BSP_CONFIG[pcw_dts]="set,pcw.dtsi" XSCTH_MISC = "-yamlconf ${YAML_FILE_PATH}"
