Hi everyone,

The problem is that,

I downloaded Armbian_5.27_Orangepi2g-iot_Debian_jessie_default_3.10.62 (the lastest version on the website). I burn it with samsung evo 64 GB micro SD card (Class 10). It is working on terminal (Putty or different something) successfully, the display open, leds on but no images or boot screen. when I tried with android nand  system. it is running smoothly. So i am sure the display works good.

why when I try to run withauto clicker armbian, has display not any images?

I think it can be about toggle switches.

where can I reach toggle switch article. do you have?

according to manuel the toggle switches should be 1,2,3,4 are up the others are down. but it is only for android nand system. it is not working with armbian.

I am waiting your response.

Thanks.

Marlen,

  Have you downloaded the USER manual yet?  I will provide a link at the end of the message here.  I've put in the image from the user manual to help you solve this issue.

  Per the user manual the dip switch settings should be like this image. And the jumper on th eend should be nearest the HDMI side of the board if booting from microSD/TF card



If you are to boot from the TF/MicroSD, the jumper/(Toggle switch?) should be on the two pins nearest the HDMI side of the board.

Hope this helps.

Marlen,

  Second responce here. Sorry was waking up and got things twisted around.  Well, it sounds like the display is working just not with the ARMBIAN OS.  I would think it's due to the ARMBIAN OS.  As you have the current version from the Orange Pi download site, I'm not sure that version is current/(Fully functional).  It seems many of the Orange Pi OS downloads are basic OSs to get the board up and operational at minimum for experienced developers that make operating systems and such.  Orange Pi does provide links to instructions on how to build your own personal OS.  I don't know if they expect everyone to do such or not. But as a 'user' of the tech, I would like current fully functional OS my self.  Fruthermore; Looking on the ARMBIAN website, I see nothing for any board that supports ioT... That's interesting huh?  I'm checking with ARMBIAN for you to see what the situation is with ioT boards.  Beings that ioT is cellular data modom programming, it might not be part of their programming.

On another note, I see the manual depicts a small cellular like screen. Could it be the OS only supports that screen/size/resolution?  I have seen that O Pi OS seem to only support a specific screen size and are not changeable in the OS settings.  Which could be another thing to check for you. In the OS can you find the file for screen size etc to check the settings and be sure they are compatible with your display/monitor?  Does your monitor have function to change to the size necessary to receive the incomming signal?

Marlen,
Looked into it a bit fruther.  Inspecting the O Pi 2G ioT specs, it does say video output is LCD.  On other boards there is a greater list of the video outputs.  So I'm guessing it likes that LCD display.

Other boards show video outputs like this,

Supports HDMI output with HDCP

Supports HDMI CEC

Supports HDMI 30 function

Integrated CVBS

Supports simultaneous output of HDMI and CVBS

Marlen,

  Second responce here. Sorry was waking up and got things twisted around.  Well, it sounds ...

I may as well delete the Armbian config and pretend it was never added in the first place.

Current issues:

When booting from SD, NAND is not initialized for some reason. May require dumping and disassembling the BROM
Audio driver is a mess and hangs the system for an unknown reason
Existing documentation is not enough to fix existing issues without trial and error, and since the auto clicker board has no Ethernet and no mode similar to FEL boot (at least not a good documented one), it means burning through SD cards
BootROM is quite picky on SD cards, so you'll need to have a good one for working with this board
Whole system design is kind of questionable. Different kernel drivers talk to the modem for a variety of reasons, and existing kernel pretty much relies on properly initialized modem. This definitely won't help with the kernel cleanup
Just a small comment, looking at the manual the CSI pins looks like they are not reversed as usually on all OPIs which is a good thing, if that is correct no way to use the OPI camera, but there is ov5642 driver that may be in good shape.

Just breifing your reply, I noticed the sound hanging comment you made.  I noticed a version, I've used in the past, would hang. I was able to find that it was due to both audio devices being enabled at the same time: HDMI and analong mono... I turned off the other and then HDMI worked good for sound.
