Add a new package to Buildroot called xilinx-fpgautil which builds the Xilinx fpgautil script which can be used for loading FPGA bitstreams on zynq, zynqmp and versal products at run-time. This is a handy application for loading FPGA bitstreams and their corresponding device tree overlays. An explanation of how this script can be used for each type of product can be found on the wiki pages below. https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841645/Solution+Zynq+PL+Programming+With+FPGA+Manager https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841847/Solution+ZynqMP+PL+Programming https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/1188397412/Solution+Versal+PL+Programming In addition, the source code for xilinx-fpgautil can be found here: https://github.com/Xilinx/meta-xilinx/blob/master/meta-xilinx-core/recipes-bsp/fpga-manager-script/files/fpgautil.c The Xilinx fpgautil script can be used hand in hand with the Versal Segmented Configuration with the following example command for programming the pld.pdi file to the Versal FPGA: fpgautil -b /lib/firmware/xilinx/<design-name>_pld.pdi -o /lib/firmware/xilinx/<dtbo-name>.dtbo Signed-off-by: Neal Frager <neal.frager@amd.com> [Luca: build-tested only] Tested-by: Luca Ceresoli <luca.ceresoli@bootlin.com> Reviewed-by: Luca Ceresoli <luca.ceresoli@bootlin.com> [Julien: reflow commit log] Signed-off-by: Julien Olivain <ju.o@free.fr>
Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
