I do not know the meaning of all parameters clearly (Any one tell me ?).
Today I update the DVSDK to 1.3 . I use the uImage on the host via
tftp  and use the file system on the host via NFS.
When I set the Uboot:
setenv  bootargs  console=ttyS0,115200n8 noinitrd rw ip=dhcp
root=/dev/nfs nfsroot=$(nfshost):$(rootpath),nolock mem=120M
The Linux is OK but the demo cannot run.
When I change to:
 setenv bootargs
video=davincifb:vid0=720x576x16,2500K:vid1=720x576x16,2500K:osd0=720x576x16,2025K
davinci_enc_mngr.ch0_output=COMPOSITE
davinci_enc_mngr.ch0_mode=$(videostd) console=ttyS0,115200n8 noinitrd
rw ip=dhcp root=/dev/nfs nfsroot=$(nfshost):$(rootpath),nolock
mem=120M
The demo is OK.

Uboot parameters can configure the fbdev.  spruek9.pdf  tell me how to
FBDev Driver Configuration

Good luck.

FrameBuffer on DM6446

2009-02-20 Thread Andre Vinicius Mulho Costa 
Hi Guys,
   i had updated to montavista 4.0.1 and tried to run a Video, but this
wasn't very successful. The running video appeared unconfigured.
  I' ve used fbset to display the frameBuffer configurations then i got
this:

*r...@150.162.62.61:~# fbset -fb /dev/fb/3

mode 720x480-60
# D: 12.500 MHz, H: 14.863 kHz, V: 59.932 Hz
geometry 720 480 720 480 16
timings 8 121 0 16 0 0 0
bcast true
laced true
nonstd 1
rgba 0/0,0/0,0/0,0/0
endmode*


And i have Montavista 4.0 running Ok, that prints this with the fbset:
*
r...@150.162.62.61:~# fbset -fb /dev/fb/3

mode 720x480-32
# D: 5.556 MHz, H: 7.716 kHz, V: 32.150 Hz
geometry 720 480 720 1728 16
timings 18 0 0 0 0 0 0
laced true
rgba 0/0,0/0,0/0,0/0
endmode*

Then I've tried to set manually the timings of the frameBuffer of Montavista
4.0.1 using this, but wasn't successful:
* fbset -fb /dev/fb/3 -t 18 0 0 0 0 0 0 *

I think that setting the same configuration of Montavista 4.0 in Montavista
4.0.1, i would get a well good video.

Does anybody has a clue of how setting this timings on the Davinci
FrameBuffer Kernel Module of Montavista 4.0.1(DVSDK_1_30) ?

Thanks everyone for the help, and sorry for the bad English.
André Costa
