HDMI Display for Raspberry Pi on Jetson TK1

Hi guys,

I recently purchased a Waveshare 7inch HDMI LCD rev C (http://www.waveshare.com/product/mini-pc/raspberry-pi/7inch-hdmi-lcd-b.htm) which is intended to be used on a Raspberry Pi. I want to make it work on the Jetson TK1.

I tested the HDMI screen on my desktop (Windows 7) and it works well. I can see my desktop on the screen. But it doesn’t show any output when I plug it in my Jetson TK1 HDMI port (which works normally with a standard screen). The screen is correctly powered-up using an external 5V source, so it’s not an issue with the Jetson USB port not having enough juice.

I typed the following command :

sudo get-edid | parse-edid

and got the following output :

This is read-edid version 3.0.1. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 0
No EDID on bus 1
No EDID on bus 2
No EDID on bus 4
No EDID on bus 5
1 potential busses found: 3
128-byte EDID successfully retrieved from i2c bus 3
Looks like i2c was successful. Have a good day.
Checksum Correct

The part I notice when it starts standing out is:

...Option "UseEDID" "false"
...Enabling 2D acceleration
...Ignoring EDIDs

It looks like the screen provides correct EDID information, and the system loads just fine up until that point. Then perfectly good EDID data is thrown out. What I don’t know is why. The option UseEDID false would seem to mean that somewhere someone configured to not use EDID…but your xorg.conf does not contain this.

I wonder if the default in the driver accidentally had this option set to false. This would explain part of some display issues.

I would suggest this experiment…in the xorg.conf file, set UseEDID true (device section):

Section "Device"
    Identifier  "Tegra0"
    Driver      "nvidia"
    Option      "AllowEmptyInitialConfiguration" "true"
    Option      "UseEDID" "true"
EndSection

Here’s the new output after adding the lines in xorg.conf file

It seems to get further along. I see this:

...Option "UseEDID" "true"
...Enabling 2D acceleration
...NVIDIA GPU GK20A/NullRM (GK20A) at SoC (GPU-0)
...Memory: 1937408 kBytes
...VideoBIOS:
...Valid display device(s) on GK20A/NullRM at SoC
...    DFP-0 (connected)
...    DFP-1
...DFP-0: External TMDS
...DFP-1: External TMDS
...Option "Ignore"
...Ignoring display device DFP-0

EDID is no longer ignored, but the connected DFP-0 is still ignored. Anyone know if the driver has a setting to force this to not be ignored, or insight into why it is ignored?

I called the command “xrandr -d :0” and got this output

Screen 0: minimum 8 x 8, current 2944 x 1200, maximum 16384 x 16384
DSI-0 connected primary 1920x1200+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1920x1200      60.0*+
HDMI-0 connected 1024x600+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x600       43.1*+

So I changed the /etc/X11/xorg.conf file in the monitor section I wrote instead

Section "Monitor"
   Identifier "HDMI-0"  # Was DSI-0 before
   #Option    "Ignore"
EndSection

And got this output in /var/log/Xorg.0.conf

1024x600 is the correct resolution for my screen, but I still get nothing on the HDMI display. I stumbled upon a forum on the raspberry pi and some of the replies seem to imply that I would have to install some specific device drivers for my HDMI display to work correctly. Isn’t HDMI supposed to work “as is” ? I do not require the touchscreen features of the display, only the HDMI output, so I figured that I didn’t need any specific drivers for the device.

From what I see it seems that the resolution of the screen is not supported by the video system. Then it says it can’t use EDID, but I think this really means it tried to use EDID and none of the settings were within the possibility of the video hardware driving it:

Validated MetaModes:
    "DFP-0:1024x600,DFP-1:1024x600"
Virtual screen size determined to be 1024 x 600
Unable to support custom viewPortOut 1920 x 1080 +0 +60
...snip...
Unable to support custom viewPortOut 1600 x 1200 +160 +0
Unable to get display device DFP-0's EDID; cannot compute DPI
    from DFP-0's EDID.
DPI set to (75, 75); computed from built-in default
(--) Depth 24 pixmap format is 32 bpp

I do want to confirm that this was the output with no other monitor connected, that the logs in question had just the RPi monitor…is this correct? Two monitors would complicate things, especially since there are times when both monitors can be required to share a common mode (and thus both would have to support the same EDID for at least some resolution).

I can’t tell you much about the X11 history, but the idea was that having EDID lets the monitor tell the video subsystem what is attached and what the monitor can do. Certain combinations of resolution and related settings are always supported in desktop monitors (and in video cards), but not necessarily in small touchscreens. The video hardware itself may be arranged such that output modes are not infinite in flexibility (e.g., because of memory alignment killing performance). It is conceivable that a different set of software could act as a kind of adapter to those modes…this tends to be a frame buffer though, not hardware accelerated video. The nVidia driver is designed for performance, and I suspect if you used an alternate driver for a framebuffer (nouveau), then video performance would drop (this may not matter to you, but without the nVidia drivers I’d also expect to lose CUDA).

What I cannot confirm is if the rejected modes from that last log are indeed simply not supported by the nVidia driver…I suspect this is the case, but I do not know for sure if some other cause is responsible.

There’s was only the small HDMI monitor connected to the system. I can’t lose the CUDA capability of the device since I am using it for some image processing. I will be looking at a different solution for the display, I don’t want to spend more time on that problem. I emailed the company that produced the HDMI display for some feedback on my problem but no response still. I will update this thread if I get an answer from those guys.

Thanks a lot linuxdev for your answers !

@KarlR

I woke up this morning to the idea of “Why don’t I use my waveshare screen on my Jetson?” So I got to it. Here’s some basic info I’ve found:

The waveshare will only work on my pi 2 when it is connected via gpio AND hdmi. Also, I have the following in my /boot/config.txt

hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

If one were to map out the rpi gpio pins, jetson gpio pins, and waveshare gpio pins then you could quickly see where the pins correlate and rig an adapter that way. That’s my plan when I have a bit more time to tinker with it.

I am also facing the same problem as @KarlR. Did you find any solution, if so please share.

It was working fine with jetson tk1 R19 os, once I update(or flashed) with R21, it stopped working.

Thank you.

It started working now.

Now I reflashed with R21 Rev 3, previous one was R21 Rev 1, in that it is not working.

Thank you.

How about the latest status of this thread?
Your report kindly appreciated

Best regards,

I have not heard of any updates. However, anyone who wants to figure out a monitor issue would be advised to install packages “read-edid” and “edid-decode”, then provide the following information:

  • How the monitor is connected, including any adapter.
  • A monitor model which can be looked up or a URL to the specs.
  • Output of "get-edid | edid-decode and "get-edid | parse-edid".
  • Content of "/etc/X11/xorg.conf".
  • A copy of log "/var/log/Xorg.0.log".

Thank you very much linuxdev for your response.

    Thank you very much for all posting of the thread member, I hope we can solve this problem together.
    
    
    
    Best regards,

Here’s a digest of information on the above…

It looks like EDID query works. parse-edid is as expected, so it should be possible for X11 to automatically configure graphics within its limitations. However, output of “get-edid | edid-decode” was truncated, I’m guessing either because it wasn’t run sudo or a copy and paste error…it is unlikely that edid-decode would fail when parse-edid would succeed. So I believe cabling and EDID response are not at issue, these can probably be ruled out as a problem.

Driver files are installed correctly with the proper Xorg ABI. This is not something a flash would change. This makes it odd to see the failure to initialize GLX message. The cause can’t be from the presence of incorrect files or symbolic links reverting to a mesa/nouveau version. It is possible that file permissions are a problem and that the X server was unable to read libglx.so because of this (or some other arcane issue). What is the output of this:

ls -l /usr/lib/xorg/modules/extensions/libglx.so
ls -l /usr/lib/arm-linux-gnueabihf/tegra/libglx.so

…it is more likely that a failure to load GLX is related to not having a monitor configured (GLX failure is quite probably not a cause but a side effect of the failed screen setup…which would mean the GLX failure is not really a clue, it’s just one of the domino effects of the real failure).

When EDID is used some (or all) of the xorg.conf may be filled in or edited automatically, and so the file itself is not necessarily a complete story of what X11 is using for configuration. However, it could be useful to manually fill in some missig parts of xorg.conf based on the EDID query just to make sure this is being used. Before doing any xorg.conf edits you may want to save a backup of this to revert to. Also, I am assuming only the one monitor is attached, having two monitors at once can drastically complicate things and invalidate debugging efforts. In xorg.conf, look at the appropriate section, and edit to become this:

Section "Monitor"
	Identifier "DFP-0"
#	ModelName ""
	VendorName "ADA"
	# Monitor Manufactured week 1 of 2007
	# EDID version 1.3
	# Digital Display
	DisplaySize 150 100
	Gamma 1.00
#        Option "DPI" "168 x 168"
	Option "DPMS" "false"
	Modeline "Mode 0" 32.00 1024 1064 1112 1152 600 613 616 645 -hsync -vsync
EndSection

Currently DPI is commented out, this may work fine, but you may also want to try with these variants one at a time (the monitor’s URL does not give DPI…if there is another URL with complete specs for the monitor it would help):

Option "DPI" "168 x 168"
Option "DPI" "96 x 96"

With those variations reboot and see what happens, keep a copy of the Xorg.0.log each time (it rotates to Xorg.0.log.old for the previous boot, be sure to keep the correct log with the correct current boot…reboot to a new setting, see if X11 logs in, save a copy of the log, and if needed, make new edits, then repeat).

FYI, it looks like display mode was picked based on this log line:

Setting mode "DFP-0:nvidia-auto-select"

This means the EDID mode was not used. One reason this might occur is if the valid EDID mode is not supported in the driver, then the driver would revert to a different mode (one which this monitor does not support). Edits beyond just a config may be needed in this case (something in kernel may need edit).

It seem that DPI can not compute from the EDID as shown on

[    12.628] (WW) NVIDIA(0): Unable to get display device DFP-0's EDID; cannot compute DPI
[    12.628] (WW) NVIDIA(0):     from DFP-0's EDID.

I calculate the DPI from http://pxcalc.com/ wtih input of 1024x600 7 inch screen and rounded to nearest common setting of 168 x 168.

I also update the Depth to 24, here was the xorg.conf setup.

as mentioned on previous digest the nvidia driver always set to 1920x1200 resolution.
It was likely as your statement that the driver might be the problem, also might be kernel possibly need edit.

I hope there is some config related setup that I can do, your guide to install correct driver and kernel edit will be appreciated.

Thank you very much.

This verifies that the nVidia version of libglx is being used with full permissions to read, it isn’t a packaging issue.

The lack of DPI is why I wondered if another URL is available which lists this. Possibly forcing DPI setting would help.

I doubt it is an issue for basic display function, but color depth is pseudo-color (8-bit), which might differ in how it works versus true-color. I have no doubt that most testing would have been performed on true-color. This has the ability to limit valid modes. You may want to try to comment out the “DefaultDepth 8”. Looking closer it appears that this is at least part of the reason why OpenGL fails…the implementation does not support 8-bit pseudo-color. Default depth 24 may not actually be what you think it is, and may also limit available modes. I’m not sure how this setting deals with alpha blending on this driver, but it could be that true-color is 32-bit with 8-bit r/g/b and another 8-bits for alpha. Try with no color depth setting (commented out), and also with 32-bit color depth.

In order to force manual configuration, try uncommenting the previously commented out line (activate the line to see if we can force something excluding EDID since we’re manually trying things):

Option      "UseEDID" "false"

I can’t imagine on this particular screen that this line is correct:

Virtual screen size determined to be 1920 x 1200

…that line may be a side effect of using EDID and not finding a suitable entry, followed by falling back to the auto select going to a default entry (and that default entry won’t work for that monitor). When auto selection fails default is always tried, 1920x1200 is probably a bad bet though…a more sane “almost always works” value might be 640x480. Hopefully turning off EDID will give a chance to force other modes without auto select kicking in.

I have been follow the linuxdev suggestion, unfortunately it does not work.
I take initiative to use fbdev driver. some scanning of screen resolution show ok however, it conflict with monitor capacity to show the resolution. Based on specification of edid also manufacturer, the resolution was 1024x600. I follow the suggestion at this site http://forum.lemaker.org/thread-15430-1-1.html to insert the framebuffer modeline of the screen, I think it was show improvement of log report.
