I'm using Ultra96 board (ZynqMP Ultrascale+), and i want to build petalinux with opencv inside with NEON and VFPV3 enabled. I followed a solution inside another post :
$ mkdir -p <plnx-proj-root>/project-spec/meta-user/recipes-support/opencv
$ vim <plnx-proj-root>/project-spec/meta-user/recipes-support/opencv/opencv_%.bbappend
# opencv_%.bbappend content
EXTRA_OECMAKE_append_zynq = " -DENABLE_NEON=ON -DENABLE_VFPV3=ON"
Now cleanall opencv and rebuild.
$ petalinux-build -c opencv -x cleanall
$ petalinux-build -c opencv
However, while NEON is enabled, printing the build information from OpenCV it seems that VFPV3 is still disabled. How can i enable VFPV3 too?
