Most of the driver’s job is just accessing memory, and that’s not worse in little cores than big ones. Because the board is completely made of metal, it can be used inside factories or “hostile” environments considered dirty and none ideal for running an SBC. If I can help in any way just let me know but PLEASE don't ask me how to program in C/PASCAL/NODE/etc. To close the tour there is one USB-C jack that is for powering while this can be achieved using the pin header too.

The first test is to test only the WAN interface, using my workstation which has an onboard GbE interface. Armbian images for NaniPi M4 V2 might work out of the box (most probably same LPDDR DRAM initialization). In any case Armbian does what everyone who uses it is used to: Provide a mostly clean OS with proper kernel. I'm ashamed to admit that I was lazy this time, just used their FriendlyWRT build and then debloated.The Nanopi-R2S also has the same issue, as you can’t connect the UART console while the case is closed.

The R4S uses the RK3399 SoC, has two Gbps Ethernet ports, microSD storage, and either 1GB DDR3 or 4GB LPDDR4.Flashing via Luci (explained below), gives the option to generate a list of installed applications for easy reinstall. However for those who are interested I leave a link to sbc-bench by Thomas Kaiser here (overclocked and active cooling). One thought for making this board really useful is to add OpenMediaVault – and that means Debian 10 for OMV 5. Also the board I’ve received came with an aluminum case, which has a dual purpose, for housing -of course- and it’s also used to cool down the CPU.

I know that the DC lines on some of my machines’ ports are weak (such as the netbook I’m currently typing on), it’s probable that I damaged the power transistors used in the current regulators by trying to boot some SBCs directly off them. 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. Of course I had to mount it very properly and totally safe with fitting spacer adapter nuts and Kapton tape like every high-grade engineer would do. The Nanopi R4S is powered by a Rockchip RK399 SoC equipped with a 6-core (Hexa Core) CPU, which is considered to be a high-end performance chip for SBCs. It may be true for OPNsense-based (FreeBSD kernel), but the linux-based OpenWRT works at ~940mbps bidirectionally without breaking a sweat.qos (usinf HTB as shaper and fq_codel as scheduler+AQM) is a viable option if not all of cake's additional features are needed. You will have to drill a hole in the side and tape it to the side of the case externally, or mill/modify the case internally.

Poor Samba performance is most probably due to combination of UAS with Seagate USB3 disks and missing IRQ affinity settings (both Ethernet and XHCI interrupts being processed on the little cpu0 core where maybe also the smbd task is scheduled to). I already do have a Raspberry Pi 4 on the network running as a PiHole and as a NAS server (for backups). At the heart of NanoPi R4S, FriendlyELEC has chosen Rockchip RK3399 hexa-core processor with dual-core Cortex-A72 up to 2.Well, starting at the beginning – the package arrived here in lockdown Southern Spain this morning in a large Fedex envelope, clearly marked PCB Board (Material: Metal and Plastic; Use: data storage). No throttling was detected, and for instance, 7-zip scores (~5800) are roughly the same as for RockPi 4C with the Rockchip RK3399 clocked a 1. To remove the ISP box, I need WAN side VLAN tagged packets, kind of DHCP specific config, 6to4 tunnelling for ipv4 traffic, etc, the r4s will handle that on wan side.
