HDMI issue - question for WayneWWW...
WayneWWW or anyone who can answer this question or can direct me to how to figure it out... If I'm booting TX2 without HDMI output connected (I'm still on L4T 28.1 release) and then try to connect its HDMI output to 1080p monitor, there's no video output on the monitor. However, if I have this monitor plugged in when TX2 is booting up, then I'm getting output from both linux fb and X11... Can you help me to troubleshoot this issue? I would like to be able to plug/unplug my 1080p monitor at will and still be able to get video output displayed. Let me know which information you need me to provide from my system... Thanks! -albertr

You'll want to post the result of: [code]sudo -s cat `find /sys -name edid` exit[/code] You'll also want to run "dmesg --follow" after booting without the monitor, and save a copy of what shows up from plugging in the monitor. After plugging in you'll probably also want to post a copy of what shows up in "/var/log/Xorg.0.log".

Is there any way to skip EDID processing and just force HDMI output to specific mode, like 1080p? -albertr

Hi albertr, Is your system able to work when hdmi connected and boot up?

albert, Sorry that I didn't read it correctly. To make your error in conclusion, your monitor does not work when hotplug but works good if connected and boot up? If so, then it is a new problem here. In rel-28.1 there was no report about hotplug issue.

Hi WayneWWW, Yes, that's correct, this monitor can only work if it's attached during kernel bootup process. Please see the kernel messages below for this scenario. Specifically, I'm curious what the following message means: [code] tegradc 15210000.nvdisplay: hdmi: using fallback edid [/code] [code] 81.512058] reboot: Restarting system [0000.261] I> Welcome to MB2(TBoot-BPMP)(ver [0x84a00000 - 0x85300000] [0000.279] I> bit @ 0xd4lized [0000.294] I> pmic: reset reason (nverc) : 0x0 [0000not find any partition table for 00000003 [0000.316] E7 partitions in 00010003 device [0000.333] W> 0 [0000.346] I> Loading partition bpmp-fw a9, num_blocks: 1 [0000.371] I> Binary(16) of size 528400 is l0.386] I> A/B: bin_type (17) slot 0 [0000.3Addr: 0xd79f0000, start-block: 58741437, num_blocks: 1 [0000.414] I> Binary(17) of size 465760 is loaded @ 0xd798e200 [0000.592] I> BPMP-FW load address = 0xd78000 found in scratch register [0000.610] W> RetI> Reading two headers - addr:0xd7300000 blocks:1 [0000.6270.641] I> Init SCE [0000.643] I> Copy BTCM se: bin_type (13) slot 0 [0000.659] I> Loadin000000, start-block: 58732545, num_blocks: 1 [0000.681] I> Binary(13) oflt slot: _a [0000.695] I> A/B: bin_type (20ks:1 [0000.710] I> Addr: 0x85300000, start-block: 58733057, num_blocks: 1 [0ams(VA) @ 0xd7200000 [0000.735] I> CPUBL-parumber is found in scratch register [0000.75 [0000.763] I> Reading two headers - addr:0x84a0f400 blocks4a0f400 [0000.783] I> Copying Monitor (length: 0xery Memory Start:80000000 Size:70000000 [0000.802] INOTICE: BL31: v1.2(release):cc5fd7c NOTICE: BL31: Built : 00:44:34, Jul 20 2017 NOTICE: Trusty image missing.

Hi WayneWWW,

Yes, that's correct, this monitor can only work if it's attached during kernel bootup process. Please see the kernel messages below for this scenario. Specifically, I'm curious what the following message means:

Right now I'm using Auvidea J120 board, but I believe I had the same problem with DevKit board as well. Which device has address 0x50 on I2C bus? I'm attaching my device tree FYI... Also, I had to mention that this monitor gets its power from USB bus and currently it's plugged into J120 board. I'm not sure if it's a race condition between time when it powers up and time it negotiates HMDI link, I'll try to power it from independent circuit next and will let you know if there's any change. -albertr

So, it looks like when EDID cannot be read, then monitor works. When EDID is read, the monitor doesn't work. Does it mean there's something wrong with interpreting the EDID data read from this monitor? Is there any way to force HDMI output into specific mode without relaying on EDID data? -albertr

albertr, So, it looks like when EDID cannot be read, then monitor works. When EDID is read, the monitor doesn't work. -> This is wrong. Both case would read EDID, the difference is that hotplug also relies on HPD signal. Please move to devkit if possible. Note that Auvidea J120 board is not NV officially support carrier board. Is this device tree directly picked from our release?

Hi linuxdev, I think that's correct, but I'm not 100% sure anymore since I was plugging/unplugging/rebooting so many times in a row... ;-) If you want me to re-run any of the tests, I can do it later tonight when get back home. I also tried to isolate possible power related issues (since this monitor gets its power from USB bus), so I powered it from independent source, but it didn't fix it. I'll try to replace HDMI cable next to eliminate the possibility of a bad cable and will let you know. I also have a 4K monitor available, will try to test it too to see whether it has issue or not. And the last test as suggested by WayneWWW is to swap TX2 module back to DevKit board and test it there, but I'm almost completely sure that I've seen this issue on DevKit before, so I doubt it's Audviea J120 to blame. Especially since Auvidea was using the same monitor to demo their carrier boards (although most likely with TX1 modules and running earlier version of L4T..). -albertr
