With the Versal Segmented Configuration, it is possible to load a PL bitstream at run-time using the Linux fpgautil application. Whenever Segmented Configuration is used, both the boot.pdi and pld.pdi files will be available to Buildroot. For this reason, this patch improves the user experience by installing the pld.pdi file to the target file system for run-time loading whenever Versal Segemented Configuration is used. If the fpgautil application is available in the target file system, it can be used for loading the pld.pdi using the target command below. fpgautil -b /lib/firmware/xilinx/*_pld.pdi The source code for the fpgautil application can be found here: https://github.com/Xilinx/meta-xilinx/blob/master/meta-xilinx-core/recipes-bsp/fpga-manager-script/files/fpgautil.c Along with usage details: https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/1188397412/Solution+Versal+PL+Programming Signed-off-by: Neal Frager <neal.frager@amd.com> Reviewed-by: Luca Ceresoli <luca.ceresoli@bootlin.com> 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.
