Hi all. 
I've recently received the Odroid N2+. Since nobody else started a topic about it, I'll be the one. 
All works fine with Armbian since not much hardware changes have been made vs the N2. Except for the CPU frequency.

 

With the Odroid Ubuntu you can set it to 2.4Ghz for the big cores A73 as overclock (2208 stock)., and 2016Mhz for the A53 cores (1908  stock). 


With Armbian the max clocks are 2Ghz for all cores. Using Armbian Focal 4.9 legacy.
I tried setting the higher values in config.ini. Also tried with the "meson64_odroidn2_plus.dtb" file from the Odroid Ubuntu. Doesn't boot with that. (What do I know :D)

Other changes are the RTC battery that's now on the board. 
The heatsink has changed a little. But it's still more than sufficient to keep it cool even when overclocked. 


USB3 still rather s*cks on it. Slow and a lot of issues with 2.4Ghz dongles(wifi/keyboard...).
Too bad they didn't do anything about that. But that probably could have complicated compatibility with N2 images. 

Also feels a bit more sluggish than RK3399 on NVMe vs 128GB eMMC on the N2+.  That's what fast I/O does. I'll try on USB3-NVMe later.

Here some pictures. 1st pic the N2+ with its case open.
2nd picture the N2 left and the N2+ on the right.

Cheers all.

tobetter's Gnome-wayland is the best build I've ever used out of my 2 SBC's.  Rock64 and the N2+.   Just got the N2+ last week and it's as good as folks are saying so far.   So today I built Armbian Deb bullseye-dev for it and I thought you might like to know how it went.

 

Flashed to sdcard booted first try.   Same as the Ubu focal-dev last week.   Both run great but the nic on the UBU broke as you know using armbian-config to upgrade it to nightly.   The bullseye nic won't download during first upgrade faster than 1-10k p/s.

Popped a wireless nic in , finished upgrade and rebooted.   Solid blue/red lights no boot.   Maybe they are related.

 

Figured you could use the info.  When I get free time I like to experiment with cutting edge builds of a few arm distro's.  

FYI   I'm waiting for a patch set for mainline kernel on Manjaro hoping panfrost gets support working soon through mesa.

At this time the tobetter libMali drivers seem the way to go until then.  I will attempt an Armbian KDE build/install when panfrost/mesa/mainline is more advanced.  

 

Cheers, Archetech

 

Update  8-13-20         Thanks to the dev team I can report that my N2+ is now officially OC'ed to 2100  vs 1800 Mhz and idles at 29 C.    Lanefu built the latest Boot stuff  and I hand edited the boot.ini to match the new dual use- n2 and plus one at github.  Sadly we confirmed the nic can't receive well at all.   Looking forward to more progess on this SBC.

Here my Linux review of the Odroid N2+.
It has a beastly CPU, but is lacking in I/O.
Here's my video.

 

  

Ubuntu 18.04
-
No autofill in terminal.   sudo apt install bash-completion
Can't change keyboard layout to Belgian
5Ghz wifi adapters not working/No kernel headers to install
+
Good video playback with Firefox in 1440p res. up to 1440p video. But no VPU acceleration. Light screen tearing.

sudo apt update
sudo apt upgrade
sudo apt autoremove
sudo apt install exfat-fuse exfat-utils   #for Ubuntu 18.04
sudo apt install bash-completion zram-config geany

sudo geany /media/boot/config.ini
#set cpu frequency and display resolution

XFCE ArchLinux
-
Display resolution can't be set, not in OS or config.ini
No on-board sound. USB audio adapter works


Temperatures / Hottest day of the year
------------
Idle OC           43°C
Max OC            77°C   Heavy throttle at 75°C after 10 minutes from idle
Idle default      40°C
Max default       73°C 

Power consumption
-----------------

N2
--
- IDLE : ≃ 1.9W (Performance governor)
- CPU Stress : ≃ 5.5W
- Power-off : ≃ 0.2W 
N2+
---
- IDLE : ≃ 2.2W (Performance governor)
- CPU Stress : ≃ 5.9W (@2016/2208MHz), 6.2W (@2016/2400MHz)
- Power-off : ≃ 0.2W 

SD card reader / sandisk extreme 128GB
--------------
77.8 MB/s read
28.3 MB/s write
0.51 msec access time

USB3 with NVMe to USB3 
----------------------
318.9 MB/s read
215.5 MB/s write

The same NVMe on the M4V2
389 MB/s read
392.7 MB/s write

eMMC 32GB read 166.1 MB/s

-
No on-board wifi. 
Interference with USB3 and 2.4Ghz wifi dongles. Better to use the OTG port for these.
Can't change display resolution in OS
Throttling at OC clocks
+
Most powerful ARM CPU in -100$ SBC.
Very low consumption.

Armbian is ofc in better shape but even we were throwing weeks on this board we could not bring it to the level worth associating with Armbian ;)

Currently updating download infrastructure, so slow direct links only at this point:

I've build a Armbian_20.08.0-trunk__Odroidn2_focal_current_5.7.15_desktop.img 2 days ago. The config.ini file was adjusted for the N2+. But I couldn't get N2+ clockspeeds. Big cores stayed at 1.7Ghz, whatever I tried. Forgot to mention it.
I'll try these images later. Thank you.

It should work - I will also double check once I find some time. Last time it was working normally - also I managed to enable fan support.

But manipulating speed in armbian-config might not work properly https://armbian.atlassian.net/browse/AR-396

Works as expected at 2.4Ghz and 2Ghz.  Installed to NVMe over USB3. 
I only don't understand why my 5Ghz wifi dongles don't work with it. Worked on my 5.7.15 build. Works on M4V2 legacy. 
Have they been left out for some reason? I'll try the 5.7.15 tomorrow. Thank you.

Sorry for my noobish question. How do I set it correct in my build? kernel configuration -> networking -> wifi or so? I've no clue.

Thanks. For others.

To build with wifi drivers

https://docs.armbian.com/Developer-Guide_Build-Preparation/

  

sudo ./compile EXPERT=yes
Then choose "Show a kernel configuration menu before compilation"
At kernel config -> Device Drivers -> Network device support -> Wireless LAN -> select the devices you want

I'll share my image if everything works. I've included realtek and ralink drivers.

Didn't work. Makefile:1102: recipe for target 'drivers' failed
ERROR in function compile kernel [ compilation.sh:411 ]
Kernel was not built [ @host]

Unable to install the driver manually on legacy focal.
Been using this source : https://github.com/cilynx/rtl88x2bu
Installed kernel headers. Installed dkms.
Followed instructions :
  

cd rtl88x2bu
VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER}
sudo dkms install -m rtl88x2bu -v ${VER}
sudo modprobe 88x2bu

All goes well until : sudo dkms build -m rtl88x2bu -v ${VER}

  

nicod@odroidn2:~/Downloads/rtl88x2bu$ sudo dkms build -m rtl88x2bu -v ${VER}

All I know is that I know nothing about this :) I hope a clearer brain can see some light in it?

Also tried downloading firmware-realtek.deb from debian. It installed without complaining, but didn't make my 5Ghz dongles work.

USB3 with NVMe to USB3 ----------------------

318.9 MB/s read

215.5 MB/s write

The same NVMe on the M4V2

389 MB/s read

392.7 MB/s write

Comparison with NVMe is incorrect. :)

You used an "incomplete" nvme device that runs twice as slow as a normal M2 slot. For tests, you need to use devices with "full" M2 Nanopc T4 (Nanopi M4 uses only two lines out of 4).

USB sucks compared to a full-fledged NVMe.  I have a quality NVMe + Nanopc T4, NVMe speed is 3 times higher (> 900 MB/s) from the values that Nanopi M4 shows in your test.  :)

I din't explain correct. It is the same test with USB3 to NVMe adapter on the USB3 of the M4V2. Not over the NVMe slot. Then it does +750MB/s. 

Also if I use a sata to USB3 adapter with sata SSD I get the same results. Slow on the N2+/N2. Near 400MB/s on the M4V2. 
Khadas VIM3 has the same issue, but is a bit better than N2/N2+. 
Changed it for clarity. That text file is what I use to note everything I need for my review. I share it here since some people rather read the text than to watch the video.

Hello

I think there is strange behawior in N2 board.

http://ix.io/2xET
In default cpu frequency script settings.: setenv max_freq_a73 "1800" htop and xfce4-cpu-monitor show 1900MHZ for A73

When i changed it to setenv max_freq_a73 "1908" there is 1800MHZ in htop and xfce-cpu-monitor.

 

I have also N2+ board and there is everything ok

Don't know if this is the right thread but my log gets spammed with:

Am I missing something? I installed armbian now a few times always with the same result.

 

Also here is the output of 'cat /proc/cmdline'

On most recent image this should be correct since max CPU speed in the user land was bumped to 2.4
https://github.com/armbian/build/commit/6c26c35344f283ba282a2f0adba05203440ae928#diff-e23e978e7f10e4dd5d02692593354d0b


Edit /etc/default/cpufreqspeed and adjust.
