Orange Pi Zero 3. I followed the instrutions of the first post, but I can't test HA using mpv beacuse I am running a headless server

tried mining feathercoin, git clone https://github.com/ghostlander/cpuminer-neoscrypt lots of missing dependencies to build that apt install automake autoconf-archive pkg-config libtool libcurl4-openssl-dev but once done it is autogen.sh, configure, make next register on https://www.mining-dutch.nl/ then run ./minerd -D --algo=neoscrypt --url=stratum+tcp://mining-dutch.nl:9993 -u username.worker1 -p d=10 a whopping 1.1 k hash/s on each core, well not very impressivve, but it mines i think this is no Neon SIMD Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq Tcpu C.St. 20:22:02 1416 MHz 3.90 100% 0% 0% 99% 0% 0% 53.2 °C 0/7 20:22:07 1416 MHz 3.91 100% 0% 0% 99% 0% 0% 53.2 °C 0/7 20:22:12 1416 MHz 3.92 100% 0% 0% 99% 0% 0% 53.4 °C 0/7 ^ this is with the fan on optimise it a little in makefile #CFLAGS = -g -O2 CFLAGS = minerd_CPPFLAGS = -O3 -mcpu=cortex-a53 -march=armv8-a -ftree-vectorize -funsafe-math-optimizations well, just a very minor 0.025 k hash/s improvement per core. perhaps it already has Neon SIMD or that it needs 'hand optimization', that is hard. oh and it still worked as my desktop Wifi hotspot 😅

@robertoj well, Neon SIMD isn't just useful for that matrix math, it is useful e.g. as a video decoder/encoder in place of specialized on chip video hardware. it could partially explain the 'better performance' of mpv (https://mpv.io/) e.g. if mpv is after all built with -o3 or that mpv uses a library that is optimised iwth Neon SIMD, it could likely practically see a performance as the on-chip proprietary video hardware which is not publicly documented. with an apparent 100% cpu usage if all 4 cpu cores are used with Neon SIMD. I think I once chanced upon an Rpi forum comment about shifting the codes to Neon SIMD instead instead of using propietary video hardware, partly as these 'small' chips has 'limited' capabilities for on chip video processing etc. it isn;'t really a bad thing if after all we'd use say an Opi Z3 as a 'dedicated' video streamer. A thing is at 100% cpu, non compute threads may struggle to get a slot to run at times, it may take setting 'nice' levels so that some threads get a higher priority. I've been thinking about running a (crypto coin) miner on it, probably would do that some time. They certainly don't get close to say even a Haswell, or Ryzen or even a 'low end gpu' but that they are faster than the 'older' 'smaller' chips for a comparison, the quoted 'old' figures https://linux-sunxi.org/Benchmarks#Linpack -mcpu=cortex-a8 -march=armv7-a -mfpu=neon -mfloat-abi=hard -funsafe-math-optimizations -fno-fast-math Memory required: 315K.

Good afternoon! I bought a server home assistant. The web used to open. the interface is at 192.168.1.141:8123, and now it’s reaching armbian and I don’t know what to do next and I don’t understand why this happened either. I’m asking for your help. Has anyone ever had such a situation? If I created the wrong theme, can you tell me where to create it, or maybe there is already such a theme?

Hi, is there currently support for NVMe storage in Armbian trunk? I tried to flash the latest build, added nvme ssd storage - but it is not seen in the system. What to check?
