    RockPi 4b 'board bring up'

    Hi - I would be happy to test Rockpi4A with accompanying heatsink, but it seems a bit expensive to order in EU ( EUR48,29 ) instead China (USD39) - once I received these items I like to contribute testing its stability at 2.0GHz. Anyway the heatsink looks decent to me and since it does not have to run 24/7 at 2.0GHz I am confident it can be "overclocked" to 2.0GHz for shorter periods, but I like to test that out for my use case ( ovpn with pi-hole ) . Applied similar tweaks recently overlocking the nano pi neo2 lts (v1.1), updating armbianEnv.txt and cpufrequtils . The key to this is temperature, based on current findings neo2 board runs for little while ( 10-15 minutes ) on 1.3Ghz which makes roughly a 10 degrees CPU increase within 6 minutes, but once it throttles back temp drops rapidly ( of course ) and as said I am condifent similar could be achieved with the Rockpi4...

    RockPi 4b 'board bring up'

    thanks very much - this makes me confident model A should be able to handle 2.02 as well although stated differently at their page " Dual Cortex-72, frequency 1.8GHz ", cheers

    RockPi 4b 'board bring up'

    Can someone show me the output of "cpufreq-info" please, wonder if model B ( and A ) have 1,8GHz freq limit or 2GHz like NEO4. thanks

    bypassing ovpn tells me theoretically I should be able to reach +/- 240Mbit upload BTW as earlier I accused RCSRDS of setting a 100Mbit cap...

    NanoPi NEO4

    The NanoPI NEO4 ( Rockchip 3399 ) might be an interesting upgrade after all as I was convinced there was a 100Mbit upload cap but "overclocking" the NanoPi NEO2-LTS gave me tops 200Mbit, 160Mbit average. Yet pity NEO4 comes with WLAN and BT, perhaps friendlyelec can release a "lite" version without these components as there is an alternative available, called "Rock Pi 4 Model A", just the size is a bit bigger: 85*54mm instead of 60*45mm ( neo4 ) thanks all will closely follow this !

    NanoPi NEO4

    thanks a lot - it indeed shows the NEO4 ( RK3399 ) is about double ( 2Ghz ) of what I can squish out of the NEO2 currently (1). Which reminds me of the cpu discussion back then. In fact I owe two NEO2 LTS boards and these should be able to handle 1.3 ( instead of 1 ), hence v1.1. Both boards run currently as ovpn server/client on stable debian9, meaning kernel 4.19 ( armbian 5.73 ). Perhaps in referred topic you can guide me thru this on a running system as updating just "/boot/armbianEnv.txt " and MAX_SPEED=1300000 in /etc/default/cpufrequtils," is not sufficient at least I set it to: verbosity=1 console=both overlay_prefix=sun50i-h5 overlays=cpu-clock-1.3GHz gpio-regulator-1.3v usbhost1 usbhost2 rootdev=UUID=5455aad0-a830-48da-b4ba-18795372ece0 usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u thanks again!

    NanoPi NEO4

    Hello, Can someone show results of "cpufreq-info" ( both on kernel 4.4 ( stable ) and 4.20 ( dev )) just to determine how things look like, please? ... My NEO2's show 1.01GHz ( kernel 4.19 ) while the "new" NEO4 should be able to get to 1.8 if I am not mistaken. Therefore in near future might replace this NEO4 with my current NEO2 boards , mainly used for oVPN and Pi-hole. At this time I get +/- 100Mbit speeds over my VPN tunnel - which for my streaming needs is sufficient - but I am always interested to see if things can be improved. Also it appears the 100Mbit limit is set by my ISP (RCSRDS), lucky me, considering " asemenea viteaza de upload international s-a marit la 100Mbps. ". Yet quoting from a site " There’s a significant single-core performance boost (+73%), and lower multi-core delta (+30%) as expected since RK3399 has 2 fast Cortex A72 cores, 4 low power Cortex-A53 cores, against 4 fast Cortex-A17 cores for RK3288. If you look into the details AES is over 10 times faster on RK3399, so there must be some special instructions used here, or AES hardware acceleration. " Can one show me some results using ovpn 2.4.6 please as for oVPN use this "single core" and "AES" stuff is important and maybe moving to Rockchip RK3399 will be worth it. Perhaps forcing use of the Dual Core Cortex A72 and disable the Quad Core Cortex-A53 [ echo "0" > /sys/devices/system/cpu/cpu[2-5]/online ] would be another tweak to speed things up? Oh, inerested in " grep -m1 -o aes /proc/cpuinfo " as well " openssl speed -evp aes-128-cbc " and last but not least " iperf3 -4 -V -c 192.168.10.2 -t 60 -b 0 -P 1" #where IP is address neo4 My NEO2 reads": grep -m1 -o aes /proc/cpuinfo aes openssl speed -evp aes-128-cbc The 'numbers' are in 1000s of bytes per second processed. type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes aes-128-cbc 53449.87k 172470.12k 364346.54k 527213.91k 606710.44k 613225.81k iperf3 -4 -V -c 192.168.10.2 -t 60 -b 0 -P 1 Test Complete.

    Hi thanks sharing this with me. tried with both CBC and GCM ( last results ) and indeed interesting results also with GCM.

  10. excellent news Igor, done well - highly appreciate all your efforts! ( and of course all others that contributed to this major )
  11. hello all - trying to find out when v5.67 will be final having all these juicy bits from DEV incorporated, in my case both NanoPi NEO2 ( older version ) and current LTS do work fine so far on this release. then again I use the boards just for ovpn so nothing to fancy ( in terms of GPU, etc )

  13. isn't jessie deprecated now anyway, since stretch came to life officially last year. I am aware many are still on jessie as it will be maintained till 2020? Anyway, DNS I assume in Stretch either " /etc/resolvconf/resolv.conf.d " or as it used to be ( thru /etc/network/interfaces ) in Jessie.
  14. thanks a lot, this helped a lot. I managed now by cleaning file " head " as that contained the google DNS entry I was looking for and is the primary entry. The tool " nmtui " still can be used to add DNS entries, but instead I believe these can be added to " head " so no need to use the text user interface. thanks again
  15. Hi - I flashed a new nanopineo2 with debian9 ( Armbian_5.44.180510_Nanopineo2_Debian_stretch_next_4.14.40 ) and set this to stable build before updating to latest "stable". Next step after reboot is to configure my static network ( eth0 ), but here things tend to be a bit different than previous flash ? Previously in advanced I edited /etc/network/interfaces to add my DNS-servers but in this build it seems " Network is managed by NetworkManager " so I instea I used " nmtui " to set these for "Wired Connection 1". Unfortunately I still see in /etc/resolv.conf : " nameserver 8.8.8.8 " first before my entries. I like to get rid of this nameserver but I am unable to find it. Anyone please? TiA!
