Hi,
I wanted to compile opencv 4.2.0 from source code but when I did the config I noticed that the Debian image does not expose NEON/VFPV3 instructions.
I did check with "lscpu" and what I see is:
==============================================
(cv) root@maaxboard:~/opencv_installs/opencv/build# lscpu
Architecture: aarch64
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3
Thread(s) per core: 1
Core(s) per socket: 4
Socket(s): 1
NUMA node(s): 1
Vendor ID: ARM
Model: 4

L1i cache: unknown size

NUMA node0 CPU(s): 0-3

==============================================
is this correct? the maaxboard ARM A-53 does support neon, right?
is this an issue of the debian build only ?
thanks
