You will compile and link the AI Engine graphs and PL kernels using v++
for the reset and reload flow as is typically done. However, during packaging you
must generate AI Engine-only and PL-only XCLBIN files. The XCLBIN inputs are defined below.
- AI Engine-only XCLBIN: Contains AI Engine metadata, AI Engine PDI, and PL metadata. It allows XRT to reset and reload the AI Engine array.
- PL-only XCLBIN: Contains only PL metadata, and it allows XRT to reload PL information.
Generate AI Engine-only XCLBIN
- Add the following constraints to a configuration file
(
package_aie_only.cfg):[advanced] param=package.generateAiePdi=1 param=package.idCode=0x14ca8093 param=package.extIdCode=0x01 - Run with v++ packager which takes the configuration file as input, as
shown:
v++ -p -t hw -f ${PLATFORM} \ --config package_aie_only.cfg \ --package.defer_aie_run \ --package.rootfs ${ROOTFS} \ --output aie_only.xclbin \ libadf.a <HW xsa by v++ linker>
Generate PL-only XCLBIN
- Add the following constraints to a configuration file (
package_pl_only.cfg):[advanced] param=package.generateFlatPlVersalXclbin=1 - Run with v++ packager which takes the configuration file as input, as
shown:
v++ -p -t hw -f ${PLATFORM} \ --config package_pl_only.cfg \ --output pl_only.xclbin \ <HW xsa by v++ linker>
