FriendlyWRT, or at least the sources for it, is just a few minor configuration tweaks for performance + default packages. Its compact size and abundant ports and interfaces make it popular in portable devices development, auto electronic devices, industrial applications, GPS systems and multimedia systems. Based on the table in the previous section, select the appropriate version of the compiler and add the compiler's path to PATH. It doesn't state that the act of observing something might change it - that is the (completely classical) observer effect. They are only at, build and ship, Debian testing / Arch / Manjaro / Suse Tumbleweed / Kali / Gentoo support quality level!

To update new driver modules, copy the newly compiled driver modules to the appropriate directory under /lib/modules. It seems like the microSD card was split into something like nine-ish partitions (could not remember and have not interest in testing this again) where most of them were inaccessible.Note: The contents of this section are based on firmware released after 2021/08/31, kernel version kernel 5. the LAN interface disconnects and reconnects repeatedly after the nano has been running for a day or two. If you want stability in a production environment or low headaches as a novice user, skip rolling releases. You may want to double check the IRQ numbers in /proc/interrupts and then do a reboot and check again to make sure they stay the same. Thankfully just a day or two after Armbian got their boot issues sorted out and it was now possible to create a proper image.

You can switch your provider and router at any moment and don’t care if your router supports the services you need. Before I teardown the device, let’s have a little family reunion with from left to right: NanoPi NEO3, NanoPi R2S, and NanoPi R4S. I then configured a SAMBA share in LuCi and the command line, to transfer files from my laptop to the USB drive connected to NanoPi R4S.For example I prefer to have the WiFi router before the WAN and some of my devices after the LAN, so the devices connected with before WAN don’t have access to the LAN devices via the bridge interface. aarch64 /aarch64-cortexa53-linux-gnu /sysroot --enable-languages=c, c++ --enable-fix-cortex-a53-843419 --with-arch=armv8-a+crypto+crc --with-cpu=cortex-a53 --with-pkgversion=ctng-1. I can see the power LED (red) is on, and the status LED (green) is blinking, but the LAN and WAN LEDs are off. As you can see from the above benchmarks, although the TCP test with the default window size reaches the maximum performance, the performance drops in the TCP parallel test.

In the tables I’ll be adding the commands that I’m using on each server/client and then I’ll add the result that iperf outputs. The difficulty is that the kernel config seems to be done in layers in a way, assembling and the merging the final config from different sources and its not completely obvious where to poke to make it work. com using the pseudonym tkaiser because while being a bit harsh and offending sometimes he is a brilliant mind and has very deep knowledge about low to lowest level software support of SBCs. I mean even the RaspberryPi model 4B offering a model with that much memory while the CPU is less powerful.With its lack of HDMI and other screen connectors this board is clearly designed for headless application like acting as a router, home server, network-attached storage (NAS), media station or everything together the same time. I noticed I couldn't access the personalbsd site while this was broken so it was likely a glitch at the other side. Very often the user-land work associated with networking is much more expensive than the driver counter-part, and it’s not uncommon to see better performance by binding the application to the big cores and the network layer to thelittle ones. As I can see there is the same problem with speed as in OpenWRT when it's doesn't use IRQ to correct CPU Core pinning (cpu affinity).
