Hi - I was hoping to include fpgautil in my OS for a custom board/firmware, and using a zynq. I followed https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841847/Solution+ZynqMP+PL+Programming#SolutionZynqMPPLProgramming-References using rel-v2020.2 of all the layers and was able to build, but the OS freezes immediately, or after a few seconds, without even using the fpgautil. [Sandeep]: When you say zynq, Are you using zynq-7000 or zynq ultrascale+ mpsoc/rfsoc? If zynq-7000 then you need to refer https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841645/Solution+Zynq+PL+Programming+With+FPGA+Manager Any thoughts on what may be doing this? I'm also using external-hdf to build for the custom board requirements. The XSA I'm including isn't too crazy, but does include a GPIO in the PL that the OS accesses regularly for temperature monitoring purposes. Could this be causing issues? Is there a workaround? [Sandeep]: AFAIK no issues from fpga drivers. Can you post this question in forums https://support.xilinx.com/s/topic/0TO2E000000YKXXWA4/embedded-linux?language=en_US as this is not related to yocto. Additionally, it would be much nicer to be able to add the line indicated in the instructions: `EXTRA_IMAGE_FEATURES += " fpga-manager"` to the image definition since that's in my custom layer, instead of the build conf file. But when I do this, I get QA errors about /lib/firmware/base not being packaged. I've tried using IMAGE_FEATURES with similar results. If anyone has any thoughts there as well, I'd appreciate it. [Sandeep]: I haven't seen any QA errors with fpga manager feature enabled and packaging bitstream and dtbo to rootfs. But I can double check. Best, Emily
