Installing the Software

See Section A.4, Alternate Boot Methods for information about booting with TFTP or NFS and using flash or the EVM’s hard drive.

4.3.7Configuring the Boot Setup for PAL Video Users

You can configure the EVM to select either the NTSC or PAL video standard during the default boot sequence. To select PAL, set switch 10 on the S3 (USER) user bank of switches to On. For NTSC, set this switch to Off. The switch causes the U-Boot environment variable "videostd" to be set to "pal" or "ntsc".

Using the "videostd" variable in the "bootargs" environment variable passed to the Linux kernel causes the corresponding video standard to be used by the display (VPBE) driver. For example:

EVM # setenv bootargs video=davincifb:vid0=720x576x16, 2500K:vid1=720x576x16,2500K:osd0=720x576x16,2025K davinci_enc_mngr.ch0_output=COMPOSITE console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/hda1 mem=120M

EVM # setenv bootcmd 'setenv setboot setenv bootargs \$(bootargs) davinci_enc_mngr.ch0_mode=\$(videostd); run setboot; bootm 0x2050000'

When the "boot" command is run in U-Boot, the value of "videostd" is substituted based on the setting of the switch.

See Section A.1, Changing the Video Input/Output Methods for information about switching to S-Video and Component video.
