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!
