Test in Linux

You have to set up TVOUT mode via a Linux kernel argument. You may set these in the Redboot boot script.

If you want PAL mode, add

tvout=pal

kernel argument. If you want NTSC mode, add

tvout=ntsc

kernel argument.

At Linux kernel boot, you will see the message

TVOUT (PAL) is primary

or

TVOUT (NTSC) is primary

respectively.

You will see the framebuffer console on the TV.
