No video output

[pille]

Hello!

 

I wrote the legacy image to a sd card and put it into the card slot. I can see something like diagnostic message and then "starting kernel". After that there is no video output. Neither over VGA nor over HDMI. Is that wanted? I tried 3 different monitors, but no chance. I can connect via ssh after a few minutes, but using a monitor and a screen would help, when there is no network. What am I doing wrong?

 

Greetings,

Pille

I should add, that everything worked with the preinstalled android image. And it worked with the main line. While I want to use the nand to boot from, I cannot use the main line.

What kind of monitor do you use?

How do you power the board?

Do you have a network cable attached with DHCP server on the network?
How long did you wait for the screen?

Do you have a blank screen or monitor shut downs because of no signal were detected?

 hello

 

i have the same problem

i've download every build of armbian for my orangepi lite.

some of them are not loading 

some of them shows me starting process - i see "file not found boot/,next", "file not found .next"

then 

"starting kernel"

then my HDMI monitor shutting down with sign "no video input". monitor = fullHD philips

orange pi blinking with red and lights green led

 

i've waited for a long

no network cable 

 

 

help pls!

It is an older 5:4 VGA monitor with a 1280x1024 resolution.

The board is powered over the power plug next to the ethernet port.

Network cable is attached and a DHCP server is running.

I am still waiting. I just leave the monitor on.

It says that the signal is out of range.

 

I also tried a 16:9 VGA Monitor with 1920x1080 and a 16:9 HDMI monitor with 1680x900.

Okay, there is light at the end of the tunnel. Had to manually set the output with a10disp. Fortunately that worked over ssh and it remembers the last setting.

Hello,

 

today I updated my BananaPi, after a reboot, I don't have a video-output.. the BPi is connected via HDMI to a NEC 55" Monitor.. LAN-cable is plugged in and it gets power via a powersupply.. any suggestion how to solve that? X11vnc works fine

 

thanks!
