I burn it using win32diskimager, rufus with DD image checked... First boot I get a green light and a red light flashing twice continously, no documentation on what two red light says so dont know what it means

Hi chocho thanks for your new image... but however i still not able to get ssh access... is it correct when i boot up the pi pc, i get the red status light flashing twice continuously? I have tried setting my LAN on my window computer to obtain ip automatically, no luck. Assign IP address like 192.168.10.20, subnet 255.255.255.0, default gateway 192.168.10.1 with no luck. The only place I could think of to change is all on my window computer side. Since I dont have the monitor i cant even nano into /etc/network/interfaces to check for configuration... I saw in the H3 board buyer's guide, tkaiser saids "Ethernet driver for H3 was the showstopper that prevented us releasing Armbian images with kernel 4.x so far." so chocho does your image have the ethernet driver?

I followed the steps in the documentation to let it boot itself, tried changing the sd cards with no luck (chocho image) It still says in putty "Connection refused" although I could ping it :/ Any image for orangepi pc with vanilla kernel 4.7 available that I could try? thanks

I get connection refused from putty. I can ping the pi pc correctly tho... Do i need to attach a keyboard into pi pc and enter a new root password first and it will allows connection? Like what it saids about partial command in this thread? http://superuser.com/questions/1107189/cant-ssh-into-an-odroid-c2-with-debian-armbian-image

Ok, so for the image chocho sent, can I use Putty with LAN cable to get command line? It will DHCP so I dont need to set ip manually right? Thanks

Hi chocho, do you have an image with Xdesktop installed?

Ah this might be the problem then. I will stay tuned for the new H3 Kernel

Igor thanks for your reply. I totally understands what you are saying. Why I get really frustrated is it works totally fine in raspberry pi 2 and 3 using raspbian image. I can modify the regulatory file and change the signal strength by changing the country. But when I do the same steps on Armbian (or as I call it switch platform to OrangePI PC) it doesn't change the country and thus the signal strength anymore. This leads me to suspect to be something to do with the OS part (they should be the same since they are both Debian isnt). Inface the wifi dongle and all other stuffs were taken from my raspberry Pi..........

How do I know if the armbian kernel have compiled with this config_cfg80211_internal_regdb enabled in cfg80211 module? What i understand now is there are two methods to call and change the regulatory. The first one is CRDA talks from userspace to the kernal when to change the country setting and the other one is without CRDA, tick the config_cfg80211_internal_regdb when compiling the kernal saves the regulatory file to the kernel and set the country default. So if armbian have complied with this option then no wonder I see two regulatory files. (one from kernal and the other one is the one I modified). How can I go about recompile the kernal? But then I cannot see the file at net/wireless/db.txt, infact I cannot even find the path specified Is there a tutorial I can follow as I am complete noob on linux... Please take a look at the bottom https://wireless.wiki.kernel.org/en/developers/Regulatory/CRDA#config_cfg80211_internal_regdb CONFIG_CFG80211_INTERNAL_REGDB If you do not want to install CRDA on a host, you can simply enable the CONFIG_CFG80211_INTERNAL_REGDB on your kernel. Once enabled you can place the db.txt from the wireless-regdb into net/wireless/db.txt. The downside to using this option is that you will need to rebuild your kernel for any regulatory updates, therefore using CONFIG_CFG80211_INTERNAL_REGDB is not recommended. If using CONFIG_CFG80211_INTERNAL_REGDB without updating net/wireless/db.txt you'll end up with the static world regulatory domain, so if using CONFIG_CFG80211_INTERNAL_REGDB you should be sure to update net/wireless/db.txt otherwise you may end up spending a lot of time debugging an issue that does not exist. To help with this a patch has been sent to print a warning when a kernel has been built with CONFIG_CFG80211_INTERNAL_REGDB but the database is emtpy. If you happen to also have CONFIG_CFG80211_REG_DEBUG then compiling of the kernel will simply fail.

upon checking The repo crda which is installed already in armbian might be old http://www.0xf8.org/2015/07/fixing-wireless-regulatory-support-crda-wireless-regdb-on-opensuse-tumbleweed/ take a look at the link above, when i do regdbdump /lib/crda it has exactly that problem. Might be the old crda that causing the problem??

Hi there, Basically I am trying to change the wireless regulatory power for the Opi PC. I follow the instruction like in this link and it worked in Rpi: http://askubuntu.com/questions/597546/iwconfig-wlan0-txpower-30mw-not-working I modified the country of BO to 30 from db.txt so I get 30dbm signal for testing purpose. When I have done all the proceedure in Opi PC and reboot I try to type " iw reg set BO" ,nothing happened - it still stayed at 00 which is the default country set. It also appears that when I type "iwconfig wlan0 channel 13" it then changed the country to China. And by then I can change the country BO by typing the "iw reg set BO" again. When I type "iw reg get" again it then change the regualtory.bin file to my modified version. But when I restart the system it goes back to default like the above. So my question is when armbian compile the system, does it have a hidden regulatory.bin file hidden somewhere? so the system choose itself which regulatory.bin file to use? other than the usual place stored in /lib/crda? Very weird indeed since it works totally fine in Rpi and I cross check the 85-regulatory.rules in rules.d it is pointing to /usr/lib crda file.

Ah i see, that make sense now. I also managed to backup the card using the gparted thing. What I find the Allwinner H3 is a bit faster than the broadcom one from Pi3. The gpu from OPi is also the same as what I use from my phone, meaning that it could run 3d games. Yet the price of Opi PC is fraction the cost of RPi3, wondered how RPi survive... Possibly a bigger community?

So basically if I wish to backup the sd card after installing the Armbian OS, how would I do that? In raspbian we put the image to sd card using win32diskimager. To backup the sd card we can just read the data back to computer and name the img file. How can we do that in armbian at least the easy way? Why we can view raspbian image's folder from window? What I understand is linux use ext4 file format which window cannot recognise as with armbian sd card? Many Many thanks!!

hahaha I found out the problem! Its the power PSU! I used a USB cable, cut the wire, take the positive and negative out and solder it directly to the board since I dont have the power plug before. The wire is too thin for 2Amps to pass. Ran down and bought the cable and is all good now. Thanks Zador for your help!

In fact I am using RT5370 to connect to the LAN network. Let me try from eth0

Both XRDP and SSH are active (running). Regarding the ping it is acting weird, i get 2/4 packet loss from pinging. Firewall on the armbian image? I thought XRDP use SSH protocol to communicate with OPi acting as server and computer as client?

the command works many thanks zador! one more question tho.. How do I enable SSH? I installed XRDP and try to run RDP from Windows it doesnt connect, putty also doesnt connect. I am running the Window and OPi in the same LAN so shouldnt be network problem

Hi basically i am switching from Raspberry pi to orangepi PC. Managed to find armbian which looks way better than raspberry gui! Now my problem is i used raspi-config to set login after POST in CLI in Rpi but in armbian we dont have this config thing and I want to make the system login at CLI then I could either continue to use CLI or go into gui mode by typing startx. Any ideas for this? I have tried systemctl enable multi-user.target but it seems nothing change and I also tried to find the directory of grub but there is none at armbian. Many thanks, Gabriel
