So I boot in Lubuntu, log in to orangepi with psword orangepi. Start terminal, now what? Where are the config files that need changes etc?

and donot pull out power that way Cuz there are chances that your Sd card would get corrupted(specially while you were doing heavy tasks with it) :/

Hello. I am testing my OrangePI board. For 1 day.
I write debian server image into SD card.
I have meet serveral problems
1. hdmi show nothing to dvi monitor. (I suppouse the problem is in HDCP)

So I have to buy new monitor or HDMI spliter.
2. no eMMC driver in kernel. So 8Gb flash inaccessable.
3. I can login trough ssh root@board_ip. It works fine until it overheat over 70C. It turns off 1 core. So I make heatsink. When run "openssl speed &"  4 times to load all 4 core. Max temperature riched 54C. I found I can turn on/off cores through /sys directory at a runtime. Very funny.
4. But when I try to create new user or try to login user orangepi it login and exit immediately. Only root can login o_O
5. I read forum and findout there is no opengl support in linux. It present only in android image. I can't test because I have no video output yet.
6. When I try to download kernel and build it from source I found there is very poor documentation for H3 processor. Moreover SunXi linux is not opensource where are a lot of binary blocks hardcoded source files. I try to find out how to enable hdmi output to turn off hdcp.
I found for Allwiner H3 (sun8iw7p1) no code at all. For sun8iw6 I found function Hdmi_hal_hdcp_enable

https://github.com/allwinner-zh/ ... nxi/hdmi/drv_hdmi.c
...
type = script_get_item("hdmi_para", "hdmi_hdcp_enable", &val);
if(SCIRPT_ITEM_VALUE_TYPE_INT == type) {
      Hdmi_hal_hdcp_enable(val.val);
}
Hdmi_set_reg_base((__u32)ghdmi.base_hdmi);
Hdmi_hal_init(boot_hdmi);

      return ret;
}
...
void bsp_hdmi_set_addr(unsigned int base_addr) {
      uintptr_t para[5];
      int ret;

      hdmi_main = (int (*)(int type, uintptr_t* para))HDMI_MAIN_START; // <<<<< BLACK MAGIC !!!!!!!!!!!

      memset(para, 0, 5*sizeof(uintptr_t));
      para[0] = (uintptr_t)base_addr;

That the F..K. Is it opensource or not. I have to reverse engeener opensource, to improve or modify code? o_O

Even better...while looking through directories my PiPlus quit responding. Mouse pointer could move but nothing was selectable. Could not close terminal, could not select anything in GUI, could not power down. Pulled the power plug, paused, plugged back in and nothing but green light. Switches do nothing, monitor shows nothing. Pulled power, pulled sd card. Apply power, no lights, no android, nothing.

Cooled down and works again...

That means your pi processor over heats so it's about time to fix a heat sink.

Survive-Pi · Published in 2015-10-4 13:38:44

Ok. I have installed large heat sink and fan. Runs cool. Try to install loboris debian xfde image. Rename *.img.opiplus to *.img. Rename script.bin.*plus-1080p60 to script.bin. Install SD card in pi, power it up, monitor flashes to 1080p60, boot messages flash by too fast to read, then stops and asks for login and password...still in command window. Enter orangepi and orangepi and it just asks again...and again...and again...

Board will not boot.
Step 1- Confirm correct/adequate power supply.
Step 2- Double check your work creating uimage.
Step 3- Try a different SD card. success!!!!!!

I feel this is among the most important details for me. And i am glad looking at your report. But want to remark on some general things, The web site style is excellent, the articles or blog posts is truly great : D. Very good work, cheers jun88

I’d need to talk to you here. Which isn’t something I do! I like reading a post that could get people to believe. Also, many thanks for permitting me to comment! tải app 69vn
