No output from hdmi

Hi,

I used intel drone very well.

I installed ubuntu successfully, and I used it well.

However, it suddenly did not output any signal from hdmi.

After turning on the intel drone, the computer seems like to be powered on, but I cannot see any output from the hdmi.

I tried to use keyboard without screen as following steps

1) I opened terminal window with Ctr+Alt+t

2) $ sudo poweroff

3) put password and hit enter key...

But, it did not work......intel drone was still powered....

Also, to escape from the sleep mode or something, I pushed the power button after turning on intel drone.

But it does not work.

(Pushing the power button for a few second to power off does not work neither.)

To show LED light patter, I give two links.

2. https://youtu.be/2TBXhJqpeJw 09310A86 9E83 4092 8051 0618E851A2FF - YouTube

Please help me to resolve this issue.....

Do I need to send it to service center?

What is the coverage of warranty?

I bought it last summer...

Thank you.

Hello Inteldrone,

 

 

Thank you for your patience.

 

 

Are you able to see the axis point that Aero creates? If you can, you can connect through SSH into the drone and try to reboot it from there.

 

 

Also, have you performed a BIOS update before the HDMI stopped working?

 

 

Regards,

1. What is the axis point? Are you talking about network SSID? or...?

2. I did a BIOS update before the HDMI stopped working.

However, it worked well after the BIOS update.

I detached the Intel Aero Compute Board, and I tried to start it with wall power supply.

It is powered up, but it did not show any output of HDMI....the same symptom.

Thank you.

Hello Inteldrone,

 

 

I apologize for the confusion.

 

 

I was referring to the access point of the aero drone.

 

 

You can follow this guide to connect to the access point: https://github.com/intel-aero/meta-intel-aero/wiki/08-Aero-Network-and-System-Administration# networking-lte

 

 

Also, I would suggest you to attach the compute board back to the drone.

Hi,

sorry for tardy reply.

I still need a help.

I cannot find any access point.

the computer was powered on, but it did not work at all.

Your answer is not helpful at all...

AS I ALREADY SAID THAT

"I detached the Intel Aero Compute Board, and I tried to start it with wall power supply.

It is powered up, but it did not show any output of HDMI....the same symptom."

Please advise me with correct answer.

Do I need to send it to customer center?

Hello Inteldrone,

 

 

If you plug a direct micro USB cable between your PC and Intel Aero, it will create a USB-ethernet adapter and allocate an IP address for your PC.

 

 

You can then access Intel Aero over this USB cable with IP 192.168.7.2

 

 

Please note that you will first need to install RNDIS drivers if you have a Windows host.

 

You can get the driver from here: http://www.driverscape.com/download/rndis-ethernet-gadget http://www.driverscape.com/download/rndis-ethernet-gadget.

Please follow driver update process as mentioned in below link,

 

https://www.lifewire.com/updating-drivers-in-windows-7-tutorial-2619224 https://www.lifewire.com/updating-drivers-in-windows-7-tutorial-2619224

 

After that you should be able to use Putty to connect to ssh to Aero through that IP.

 

 

Hope this helps.

 

 

Regards,

 

Octavian

Hi, Intel Corporation thank you for your reply.

First of all, I would like to confirm what is the issue in my case.

I am not sure the computer is working without hdmi output.

I do not know what is the condition of the computer.

Even, I cannot check the status of the computer.

What I only know is that the computer is powered on.

Plus, after Intel Aero is powered on, I cannot power off.

I pushed the power button for a long time, but it did not work at all.

So I need to try something to resolve the issue.

As a one trial, I followed your instruction.

I connected PC to Intel Aero using usb cable. That is, "micro USB of Intel Aero" to "USB of pc"

But the pc did not detect any new devices at all in the "Device Manager"

What is in the Device Manager > Network adapters is the following.

1. ASUS PCE-N1511n Wireless LAN PCI-E Card

2. Intel(R) Gigabit CT Desktop Adapter

3. Qualcomm Atheros AR8161/8165 PCI-E Gigabit Ethernet Controller (NDIS 6.20)

I expected something appeared as like when I plug USB stick in.

But nothing appeared in Device Manager when I plug in USB port to my pc.

Do you mean that Intel Aero can be detected in "Network and Sharing Center"? (I am using Win7)

I need a warranty. What is the warranty policy of this?

I bought it last summer.

Thank you.

P.S. Hi JoshDavisNC, In my case, the computer is able to be powered on. But, Nothing is displayed on the monitor.

Hi inteldrone,

 

 

The board might be in an un-bootable state after the BIOS update.

 

We will get back to you with further instructions.

P.S. I updated BIOS before. After that, it worked well for many days...

I had a similar problem, not sure if it's the same as yours. Have you tried plugging into a different HDMI monitor?

When I powered on, I would see the startup screen, bios setup screen, and grub screen, but as soon as it started to boot, my HDMI monitor would give me a blue screen and say "No Signal". This was a cheap $50 7" screen I use with Raspberry Pi boards all the time. I plugged the drone into a different HDMI monitor and it worked.

I have a similar issue. HDMI was working fine then stopped working. However, I can PuTTy into the drone. I have had this happen with two drones recently. I tried different monitors and micro HDMI to HDMI cables to no avail. I tried rebooting, as well as powering down and back up, to no avail.

Any assistance would be appreciated. I'm using Intel Poky 1.6.1 (pyro) with BIOS 01.00.16.

Regards,

Dan

Interestingly we managed to get HDMI working again. We are guessing that it might be a change in inrush current on power up due to an update of the O/S. We were powering the Intel Compute board from the wall wart or a 3A power supply and neither worked, but when we hooked up a 6A power supply it started working again. Mind you, humidity (higher) and ambient temperature (lower) have also changed. We will have to see what happens over time (I had suspected a possible ground loop but I tried the 3A power supply because it is isolated and it still didn't work. The 6A supply is also isolated).

I have a similar problem.

I updated the BIOS to the current version, and the RTF booted okay.

I then powered it down and later booted it up and could not connect to it nor could I power it down. (Could only power it down by unplugging the battery)

I can get into the BIOS Setup, etc. Just when I boot the operating system, then the RTF gives response.

What do I need to do to fix this?

Thanks

I too lost HDMI after flashing the bios. 7/12/2018

From a clean factory Intel RTF drone, I installed all the updates exactly as shown in

https://github.com/intel-aero/meta-intel-aero/wiki/02-Initial-Setup 02 Initial Setup · intel-aero/meta-intel-aero Wiki · GitHub

and as is documented in the related video:

https://www.youtube.com/watch?v=e9MLnRbMDHo&list=PLTQSXsG86pGfyZm5ac6-ZtQsEniUJIE9o&index=7 Autonomous Drone Engineer - C1 - OutOfBox and Flashing - YouTube

It went perfectly, and completed all the updates to all the systems. The only difference was the version numbers were slightly newer. Drone is still running Yocto

Connected from Ubuntu laptop and Android phone through the access point and used QGroundControl to calibrate the sensors. All went well.

At this point, the HDMI still worked. The cable and monitor showed the output of the drone's HDMI port.

The drone would not shut off using the power button, so I unplugged it and rebooted. HDMI would no longer work.

I can do the following:

Connect to the drone with Spectrum DXe RC and arm motors.

Attach Ubuntu laptop and Android phone through the access point Aero-xxxxxxxxxxxx

Connect to drone in QGroundControl

SSH into the drone from Ubuntu laptop

Access drone file system from Ubuntu laptop

I CANNOT do the following

View video output from HDMI port. HDMI output has bee tried into several know good monitors (other HDMI feeds worked into these ports)

What can I do to get HDMI working again?
