  1. Thanks for this reply! Indeed, as the link you provided says, for Aarch64 the flag "asimd" stands for NEON too. I have just compiled OpenCV with neon and it was imported without any problems. Many thanks!
  2. Hello, I've been trying to compile armbian for my OrangePI Zero Plus H5 with NEON and VFPV support for OpenCV . If I use the providede default image from OrangePI I can see that NEON and VFPV are enabled with lscpu command. When compiling armbian from source or downloading the pre-compiled images, I see the following: root@orangepizeroplus2:~# 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 Model name: Cortex-A53 Stepping: r0p4 CPU max MHz: 816.0000 CPU min MHz: 120.0000 BogoMIPS: 48.00 NUMA node0 CPU(s): 0-3 Flags: fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid Can somebody help me enabling NEON and VFPV flags?
