Hi all, This is not fun....
Does my Pi system use the NEON extensions? 1) Am I running 64bit on the RockPro64? "file liblpcnetfreedv.so" returns "data" OK then, try to "fix" "file", no-go. Copy the file liblpcnetfreedv.so to my main Linux PC, we get: /tmp/liblpcnetfreedv.so: ELF 32-bit LSB pie executable, ARM, EABI5 version 1 Not 64 bit. 2) The GCC compiler, though it never objected.... gcc version 6.3.0 20170516 gcc -v returns options including: --with-arch=armv7-a --with-fpu=vfpv3-d16 --with-float=hard --with-mode=thumb And, no mention of "armv8" or "neon". So, at this stage, I can't tell you if FreeDV mode 2020 works on a 64bit Pi.
