The poor's man Beagle Board

The poor’s man Beagle Board

Well, as I don’t have a DVI monitor, I wanted to boot my Beagle Board XM by default using the S-Video output.

1. Connect the serial cable and enter U-Boot prompt @ 115200,8N1
2. Type printenv

My beagle default config in the card says (defaultdisplay=dvi)

Now things are easy:

3. setenv defaultdisplay=tv
4. saveenv
5. boot (or reset)

And there it is the default output to S-Video!

Hi th3anu, of course you can. uenv.txt simply contais the boot arguments to the kernel. Simply edit the file and put defaultdisplay=tv there at the end of the line.

But I am not sure if defaultdsplay=tv kernel parameter has changes in earlier kernel versions….
