Dear All
May someon drop me a line about the following
I am trying to run up a good gst pipeline ( to start with
videotestsrc) but i am running into this
My Device: igep0030 module
my kernel: 2.6.35.9 from here (
http://git.igep.es/?p=pub/scm/linux-omap-2.6.git;a=summary)
cmdline is : omapfb.mode=lcd:1024x768MR@60 ubi.mtd=4 rootfstype=ubifs
root=ubi0 console=ttyS0,115200n8 video=omapfb:vram:2M,vram:4M
mem=88M@0x80000000 mem=384M@0x88000000
All is compiled with openembedded.
When i play this:
root@biogas:~# DMAI_DEBUG=2 gst-launch --gst-debug=2 videotestsrc !
TIDmaiVideo
Sink autoselect=TRUE displayDevice=/dev/fb0 videoStd=VGA
@0x000e8885:[T:0x402f2000] ti.sdo.dmai - [Dmai] Dmai log level set to
'2'. Note that calling CERuntime_init after this point may cause
unexpected change to DMAI tracing behavior.

this loops till i stop the pipeline
I followed the code into
davinci_multimedia_application_interface/dmai/packages/ti/sdo/dmai/linux/omap3530/_Sysfs.c
where it loops on working out the managers ( waiting for either "lcd"
"tv" or "dvi")
also
kernel/drivers/video/omap2/dss/manager.c supports only "lcd" and "tv"
as managers
but my kernel shows
root@biogas:~# cat /sys/devices/platform/omapdss/manager0/display
tft
So do i ve a miscombination of versions here ( one knowing about a new
"tft" manager and one not ) ?
All Documents i find never talk about "tft" , where is this coming from ?
Any hints
Thanks in advance
Rob
