review fpga configuration recipe - ArrowElectronics/arrow-soc-workshops GitHub Wiki

This recipe's function is to move the FPGA Configuration RBF file from the custom meta layer to a build/tmp/deploy/images/ folder. It will then be combined into the SD card image as described in the previous section

Open the recipe socfpga_yocto_workshop/poky/meta-my-custom-soc-board/recipes-bsp/rbf/my-custom-soc-board-rbf.bb in the default editor, gedit.

The following line extends the bitbake search path to the meta-my-custom-soc-board/recipes-bsp/rbf/files sub directory.

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

The SRC_URI variable indicates that the RBF file is located in the files sub-directory

SRC_URI =     " \
                       file://soc_system.rbf \
                       "

The following lines of code create an intermediary images/MACHINE directory and install the RBF file there. The file is then copied to the build/tmp/deploy/images/ folder.

install -d ${D}/images/${MACHINE}/
install -m 0777 ${WORKDIR}/soc_system.rbf ${D}/images/${MACHINE}/
cp ${WORKDIR}/soc_system.rbf ${DEPLOY_DIR}/images/${MACHINE}/

The RBF file was created previously by the reader.Refer to the individual board links for details.
