[meta-xilinx] ['meta-xilinx-tools'] Issues with HDF output file generation: BOOT.bin and DTB not working as expected

[Brett R. Nicholas]

Hi there,

I have two questions about the meta-xilinx-tools ability to generate output files based on an HDF file:


  1.  I am able to successfully build BOOT.bin from my HDF file, however it does not automatically load the bitstream when I boot the device. Is there something else that I need to do in order to get BOOT.bin to configure the PL before launching u-boot?
  2.  I have been struggling to get the meta-xilinx-tools to generate a DTB from my HDF file. I am successfully able to build BOOT.bin, however the device tree blob that is generated in tmp/deploy/images/zedboard-zynq7 does not contain my PL peripheral (it is just the default DTB). I have already verified that the HDF file is correct. Is there something else I need to do in order to have meta-xilinx-tools create the DTB for my design based on the HDF?

For reference, you can find the relevant sections of my local.conf below. Thanks!
