After using BalenaEtcher to burn lastest image to a microSD and then an ARMbian system to do u-boot work, the NanoPi booted into setup as I was used to from x86 installations in the past. Armbian images for NaniPi M4 V2 might work out of the box (most probably same LPDDR DRAM initialization).

They are only at, build and ship, Debian testing / Arch / Manjaro / Suse Tumbleweed / Kali / Gentoo support quality level! To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average.

After removing two more screws, we can completely take out the board and see the processor is in contact with the metal case through a thermal pad, as it should be. It doesn't state that the act of observing something might change it - that is the (completely classical) observer effect.

Therefore, in my tests I’ve used this image and actually I’ve used the image that it came in the SD card with the board. 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. Tips: most of the existing embedded ARM boards such as RPi 3B have MAC addresses that are generated via software utilities. Only then I got a not really nice surprise, when I unplugged the serial-to-USB-adapter, I needed for installation. Insert the SD card into the slot, connect a cable to your network if possible or a display and power your board.

In step two, you will need to connect the board to the case using a pair of Philips-type screws, and finally assemble the bottom cover with an additional four Philips screws. 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. The GUI allows you to create additional users, which is much preferred over allowing root logins directly.

Note this is winter here, so while the ambient temperature was 30°C for R2S test against around 24°C now. To close the tour there is one USB-C jack that is for powering while this can be achieved using the pin header too.Once you send eth0 and eth1 IRQs to cpu2/cpu3 (with appropriate tunables for RPS – Receive Packet Steering – as well) performance with smaller packet sizes might improve. When dealing with wall outlet (high) voltages you should satisfy yourself that whatever you are doing is safe and if unsure, seek advice from someone who is sure.
