U-Boot MPC8xx video controller driver
|
|
|
|
|
======================================
|
|
|
|
|
|
|
|
|
|
The driver has been tested with the following configurations:
|
|
|
|
|
|
|
|
|
|
- MPC823FADS with AD7176 on a PAL TV (YCbYCr) - arsenio@tin.it
|
|
|
|
|
- GENIETV with AD7177 on a PAL TV (YCbYCr) - arsenio@tin.it
|

|
"video-mode" environment variable
|
|
|
|
|
===============================
|
|
|
|
|
|
|
|
|
|
The 'video-mode' environment variable can be used to enable and configure
|
|
|
|
|
some video drivers. The format matches the video= command-line option used
|
|
|
|
|
for Linux:
|
|
|
|
|
|
|
|
|
|
video-mode=<driver>:<xres>x<yres>-<depth>@<freq><,option=string>
|
|
|
|
|
|
|
|
|
|
<driver> The video driver name, ignored by U-Boot
|
|
|
|
|
<xres> The X resolution (in pixels) to use.
|
|
|
|
|
<yres> The Y resolution (in pixels) to use.
|
|
|
|
|
<depth> The color depth (in bits) to use.
|
|
|
|
|
<freq> The frequency (in Hz) to use.
|
|
|
|
|
<options> A comma-separated list of device-specific options
|
|
|
|
|
|
|
|
|
|
Example: video-mode=fslfb:1280x1024-32@60,monitor=dvi
