Well we do not enable neon for this tune but aom still seems to want it so I would suggest to look at the build and see if it’s disabling neon and have HAVE_NEON is not set properly

can you try adding

EXTRA_OECMAKE += "-DHAVE_NEON=0"

and see if that helps ? for whatever reason set_aom_detect_var is
enabling it where as default should be 0

Something like this     TUNE_FEATURES= "arm armv6 vfp arm1176jzfs callconvention-hard neon". But I can't do it with armv6. I have to use raspberrypi zero w so i have to make it work with armv6.
