Hi,
 
no lies...that is my understanding of things as well ;-)
 
u-boot sets the 'videostd' environment variable to PAL or NTSC depending on the 
switch. You just have to make sure that this variable is used in the command 
line. This allows the switch to control PAL/NTSC selection of output device 
(says nothing about the camera). 
 
There is nothing stopping you hard coding 'pal' or 'ntsc' for yourself and if 
you do then you can remove the 'run setboot' stuff & hard code 'bootargs', 
which I suppose make it easier to follow. (The 'run setboot' trick is only 
there to expand the $videostd variable)
 
The output of 'cat /proc/cmdline' would help as we can see exactly what was set.

DM355 EVM demo works fine with PAL, we have two of them here and only use PAL.
 
The stuff about setting up PAL mode is towards the back of the getting started 
guide, u-boot environment variables and the board jumper. It was a while ago 
now but we followed the instructions more or less (I seem to remember typos or 
cut+paste errors) and it works fine.
 
I think it's important to set the jumper as that sets the value of an 
environment variable that is checked by software. maybe. Or maybe I'm lying.

Hi,
 
I am wondering if it is a limitation of the demo program?
 
Perhaps you could study the demo source code - the camera is being detected as 
PAL (which is good) - so why/where does 'NTSC selected' come from?
 
There doesn't appear to be a command option to select PAL (according to the 
Getting Started Guide). Might be worth checking the -h output from the command 
to see if the option list has added a suitable switch for this since the 
documentation was written.

Hi,
       Thanks for reply. after changing the command linr to dm64xxfb:output=pal,
the same error message is displaying.

  Encodedecode Error: PAL camera connected but NTSC selected.

Please suggest any solution.

Nadeem

        Hi
         
        You cmd line is wrong - it should be dm64xxfb:output=pal as the DM355 
kernel is using the DM644x frame buffer driver.
         
        The default is NTSC and the kernel is not seeing your PAL setting since 
you are applying it to a non existant module

        Hi,
                I am working on DM355 EVM board. I am running the demos from 
        command line. After executing the ./encodedecode command an error 
message 
        is genrated as,
             Encodedecode Error: PAL camera connected but NTSC selected.  
        
        I am booting with the following env:
        
        setenv bootcmd 'setenv setboot setenv bootargs 'console=ttyS0,115200n8 \
        noinitrd rw ip=132.147.160.175 root=/dev/nfs \ 
nfsroot=132.147.160.142:/home/nad/workdir/filesys,nolock mem=116M \
        video=dm355fb:output=pal;run setboot;nboot \
        0x80700000 0 0x400000;bootm'
        
        Please suggest the solution as soon as possible.
        
        Thanks
        Nadeem
