Ongoing HDMI limited compatability

[longsleep]

Well whatever it is, do not expect the situation to improve anytime soon. I do not care much about display and just made it work 1080p@60Hz no further questions asked.

To understand why I do not care you need to know that the HDMI driver in the BSP Kernel driver is missing sources for "libhdmi" (similar to libdram situation for SPL). See https://github.com/longsleep/linux-pine6...i_sun50iw1 for reference.

You know, I knew of A's reputation for not being very OSS supportive but based on the BS on the KS page I figured we would at least have basic functionality out the gate. 

I was a fool, I have now paid my stupid tax for the year. Lets hope nobody wants a double installment. At least it was cheap. 

Ohh look maybe I can pay stupid tax again! https://www.kickstarter.com/projects/udo...ecommended  LOL

Pine64+ is very nice for a lot of use cases  - i am sure you find plenty people willing to buy yours if you do not want it.

To come back to the HDMI issue, if you want to help debugging get yourself a serial adapter (http://linux-sunxi.org/Pine64#Serial_port_.2F_UART) and post the full boot log (starting from boot0) to something like http://paste.ubuntu.com and share the link. The outout you need to paste looks like that one https://www.stdin.xyz/downloads/people/l...OOTLOG.txt - if you provide that some people might be interested to take a look.

Hmm... this is VGA and not HDMI:

Code:

disp0 device type(4) enable
[DISP] boot_disp:0x40a

[longsleep]

Looks similar to mine. So what does not work exactly?

Please also post the output of

xxd hdmi/hdmi/attr/edid

and cat graphics/fb0/modes

4 is 'wrong' (VGA) and should be 3 (HDMI) instead. Just looked how it's with the rather similar sun8i BSP (H3/A83T). Similar 'wrong' but there this happens in the kernel and not u-boot. Fun stuff to deal with

No, that is actually U-Boot is using a bitmask where 4 is HDMI, VGA is 8. See https://github.com/longsleep/u-boot-pine...ay2.h#L127

So, the monitor won't wake up because it is expecting "something else"(1050p/60Hz), but Pine is pushing 1080p/60Hz?

These are relative paths, most likely relative to /sys/class (don't know -- booted the Pine64 a few weeks ago the last time). You might succeed doing a 'find /sys -type d -name fb0' to know the prefix needed to chdir to or create absolute paths.

Thanks, when acting as 'smart hands' and troubleshooting using instructions from another person I tend to be terribly literal. Using the info you provided;

Code:

root@localhost:~# find /sys -type d -name fb0
/sys/devices/soc.0/1000000.disp/graphics/fb0
root@localhost:~# cat /sys/devices/soc.0/1000000.disp/graphics/fb0/modes
U:1920x1080p-0

Decided to get a bit more info using another method. I hooked my pi to the monitor and pulled EDID info. 

Code:

root@raspberrypioldpi:~# tvservice -s
state 0x120006 [DVI DMT (57) RGB full 16:10], 1680x1050 @ 60.00Hz, progressive
root@raspberrypioldpi:~# tvservice -m DMT
Group DMT has 4 modes:
          mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive
          mode 9: 800x600 @ 60Hz 4:3, clock:40MHz progressive
          mode 16: 1024x768 @ 60Hz 4:3, clock:65MHz progressive
 (prefer) mode 57: 1680x1050 @ 60Hz 16:10, clock:119MHz progressive
root@raspberrypioldpi:~# tvservice -m CEA
Group CEA has 7 modes:
          mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive
          mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive
          mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive
 (native) mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
          mode 5: 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced
          mode 6: 720x480 @ 60Hz 4:3, clock:27MHz x2 interlaced
          mode 7: 720x480 @ 60Hz 16:9, clock:27MHz x2 interlaced

Thats the simple stuff, attached is the output of;

Code:

root@raspberrypioldpi:~# tvservice -d edid.dat
Written 256 bytes to edid.dat
root@raspberrypioldpi:~# edidparser edid.dat > edid.txt

Also adding full pi serial console boot log.

Code:

root@raspberrypioldpi:~# cat /sys/devices/platform/soc/soc:fb/graphics/fb0/modes
U:1680x1050p-0

ATTENTION Moderator Note

Forum doesn't allow upload of files with the extension .log seriously? Might what to address that lol.

Have edited kernel startup params as some others have mentioned no luck 

Kernel command line: console=tty0 console=ttyS0,115200n8 no_console_suspend,disp.screen0_output_mode=EDID:1280x720p60, earlycon=uart,mmio32,0x01c28000 mac_addr=7a:6e:63:ac:21:f1 root=/dev/mmcblk0p2 ro rootwait
