Keep me informed about your results (I have not tested but it should just work the same as with my image...)

Hi Stephan,

Tested the linaro build with screen resolution set to 1280x720. Everything seemed to run well, however I got a few crashes while playing video in the background on the home screen with the message feed active:

1. This message reported for one of the crashes:

mxc_v4l2_output mxc_v4l2_output.0: Bypass IC.

2. Got a segmentation fault once, the only messages were:

Not power off before vpu open!
mxc_v4l2_output mxc_v4l2_output.0: Bypass IC.

3. Got the black screen once, xbmc was still running

There may be a very small possibility that our DDR3 settings are still incorrect, time pending I will look into this.

Any chance you could create a build for my BSP 1.1.0 rootfs, I'd like to compare results.

wolfgar · 2013-06-23, 03:44

Hi mtx,

OK I will post a build for 1.1.0 RFS...

xbmc for BSP 1.1.0

Edit :
Some comments about your issues with the 4.0.0 build :
#1 -> I guess it is the strange issue which appeared in 4.0.0
#2 -> I don't know about this one. If you know how to reproduce please tell me so that I can investigate
#3 -> It is a typical overheating symptom...

Many thanks, will give it a test drive.

When is your wandboard quad likely to arrive?

Hi mtx,

Last night I found a workaround to prevent the transient black screens, not the ones related to overheating but the ones which appeared with BSP4.0.0...
I will rebuild xbmc with this patch for your last image to check whether it also helps.

Regarding my quad wandboard, I should receive it around the 4th of July because I ordered other items (RF chips I want to evaluate for another project) which should be available at the end of this week.
I will tell you about it and my first test with XBMC if you are interested...

Last but not least, If you find reproducible bugs while testing, do not hesitate to report them, I will do my best to track and solve them...

Best regards
Stephan

Hi Wolfgar, sorry for my late response, I could not get to it sooner.
I've tested your commits from 21st June - playback of the sample files is nearly ok, except the aspect ratio - which is correct (16:9) in case of ct2-hd sample and incorrect (4:3) in case of the other three samples (mplayer in my desktop linux plays all the samples ok). On target, gplay is able to play ct2-hd and nova-hd samples only, plays them fullscreen, so aspect is correct, but not sure if due to fullscreen stretch or due to correct interpretation of the stream.
Unfortunately even with the changes, playback of live tv stream in xbmc mostly does not work - tried tvheadend and xvdr - both had the same behavior: with SD channels, there is now only audio played (before your changes it just crashed). In case of HD streams, now nova-hd stream is working (although with 4:3 aspect ratio), but the other HD streams crash xbmc. But it's not like the nova-hd stream would always work - it sometimes also makes xbmc to fall down, but I am not sure if that's because of the previous trial with other HD channel which crashed xbmc and left the xvdr in a bad state that caused also trouble with next trial of otherwise working nova-hd.
I need some more time to have a look what's happenning there as it's strange that the captured sample files can be played while the live streams mostly do not work. It's also possible that my xbmc setup for the live tv is not perfect as this is the first trial.

wolfgar · 2013-06-25, 02:00

Hi j4ns

No pb for the delay.
I confirm that I was able to play the sample streams you sent to me for test.
Sorry for the aspect ratio : I will double check what is going on and tell you (normally I just use the info out of the xbmc demuxer)
Regarding gplay : It just does not care about aspect ratio by default : you have to set the "force-aspect-ratio" property on v4lsink so that it keeps aspect ratio. (Otherwise it just stretches to full screen...)

I also have a DVB-T USB tuner : I will give it a try as soon as I can ...

Best regards
Stephan

wolfgar · 2013-07-01, 03:03

Hi j4ns,

Just an update to notice that I have given a try to my own dvbt tuner and that I confirm that it mostly does not work, even after merging last changes from xbmc and pvr-addons dev branch.
I have already found a bug and I am looking for its root cause.
As soon as I manage to get a working build for live TV I will tell you...

Regards
Stephan

Hi, wolfgar,

i am too trying to build an image with xbmc for the wandboard.
I tried buildroot but only with meagre success. Yocto would be my next try.
Right now i am using wandboard dual but i will get a quad in about a week.

Your yocto build works quite nice on the wandboard, i only had to write wandboards u-boot and kernel to sd and exchange /lib/firmware/vpu/vpu_fw_imx6q.bin with vpu_fw_imx6d.bin and add wandboard modules.

Unfortunately i encountered some errors with 1080p playback:

Hi xn2000

Thanks for this feedback,
Can you please post the boot kernel messages (using the "dmesg" command for instance)
I am especially curious about the section "Virtual kernel memory layout" as it seems that you don't have enough available memory for DMA (I allocate contiguous physical memory so that DMA engines can be used between VPU -> IPU blocks and the main cpu is not involved in any copy by itself)

Regards
Stephan aka wolfgar

PS : By the way I have just received a wandboard Quad so this board is very likely to become my main dev board Wink

This is so great!
Thanks for all the work you put into this. As soon as this is considered somewhat working, I'll other one and replace my slow raspberry. (I still really, really like this little device!)

Thanks again, its really appreciated!

Nice

I am really looking forward to see your progress on this.

My screen randomly goes black, audio keeps playing aprox. 15secs. I suspect xbmc crashes while dvdplayer or paplayer keeps playing until its buffer is empty.
It happens while playing videos and also in menus.

Process is still active

Hmm seems like xbmc keeps running but screen is black. Logging goes on. Keystrokes get recognized.

EDIT:

I just saw that you posted a workaround for the black screen bug. Is it the one that i experienced ?

wolfgar · 2013-07-03, 23:38

Hi xn2000

Thanks for your answer : You seem to have a similar memory layout as I have on my gk802 which is able to allocate the dma buffers without trouble so I don't understand for now...
Anyway I should have my own board up and running very soon (still a little power supply issue but not a big deal ...)
So I will experiment and you can be sure that it is my priority Wink

Regarding the black screen , it may be an overheating issue :
Can you monitor the core temperature : (it is made available in xbmc GUI or you can get it by reading the special file /sys/class/thermal/thermal_zone0/temp)

More news very soon...
Best regards
Stephan

wolfgar · 2013-07-04, 02:36

Me again
Please try this xbmc binary
You have to decompress the file and to replace the file /imx6/xbmc/lib/xbmc/xbmc.bin on the target

It works on my wandboard ...

By the way : on the wandboard the core cpu temperature does not go beyond 50°C while (for the same use cases) the temp was 80°C on the GK802 (even with my additional heatsink on the case). Things are REALLY different with a properly designed board ;-)
