Omapdss Managers confusion

Omapdss Managers confusion

[Robert Wörle]

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.

Display Output.
@0x00105a82:[T:0x4185a490] ti.sdo.dmai - [Dmai] Attempting to change to 3

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

never mind ..
i think i found it .. my board code named my video device "tft" instead 
of "lcd"

duhhh

sorry to bother anyone
