Sorry for the late reply, but I didn't have anything to contribute before.
Now that Scarthgap-next is available, the hdf-examples has completely changed in
the way it works.
We now recommend that you place your configuration within your machine.conf
file. If you use gen-machine-conf this will already be done for you, but if you
are manually writing them you would add:
# Add system XSA
HDF_URI =
"https://petalinux.xilinx.com/sswreleases/rel-v2024.2/hdf-examples/2024.2/2024.2_1104_1_11050118/external/zcu102-zynqmp/zcu102-zynqmp-2024.2_1104_1.xsa";
HDF_URI[sha256sum] =
"4fcd33f790484f0e6dde5ea32aa04a82a37eea5be4ca0ccf10c3f627b2cbf57f"
NOTE the URI can be a file, if you do specify a file, then no sha256sum is
required (but we do recommend it).
This is a generated file for 2024.2 based Vivado:
https://github.com/Xilinx/meta-xilinx-tools/blob/scarthgap-next/conf/machine/zcu102-zynqmp-2024.2.conf
(For other versions of Vivado we have other generated examples.)

Hi,
I recently ported from honister to langdale and I'm now working on scarthgap. I
use a local hdf file. I noticed that when I switch the meta-xilinx-tools from
the "honister" tag to "langdale" or "scarthgap" the mechanism to pull a local
hdf fails. I believe its due to this code right here starting on line 86 (in
external-hdf_2024.1.bb):
elif d.getVar('HDF_BASE') == 'file://':
# file:// default to the full path
hdf_name = "${S}/${HDF_PATH}"
The Example for using a local file starting on line 44 shows:
# Example (local file):
# HDF_BASE = "file://"
# HDF_PATH = "${TOPDIR}/conf/my_example.xsa
# The recipe will use the XSA from ${TOPDIR}/conf/my_example.xsa
Using the above pattern implements an absolute path in HDF_PATH, but when the
code at line 86 executes, it ends up making a path from ${S} in the working dir
with the entire absolute path embedded in it. This ends up with the following
error:
"
ERROR: external-hdf-2024.1-r0 do_check: Unable to find
/home/engineer/my-proj/regression-2024.1/oe-scarthgap/builds/distro/tmp/work/zcu104_zynqmp-linux/external-hdf/2024.1//home/engineer/my-proj/regression-2024.1/oe-scarthgap/builds/distro/conf/system.xsa. Verify HDF_BASE, HDF_PATH and HDF_NAME.
"
If I dig down into the tempdir I see that do_fetch or do_unpack did not or could
not create that directory within ${S} for the recipe.
Could you please verify that the functionality is working correctly and/or that
the instructions match the implementation?
Thanks
-David
