| 33 | "video-mode" environment variable | |
| 34 | =============================== | |
| 35 | ||
| 36 | The 'video-mode' environment variable can be used to enable and configure | |
| 37 | some video drivers. The format matches the video= command-line option used | |
| 38 | for Linux: | |
| 39 | ||
| 40 | video-mode=<driver>:<xres>x<yres>-<depth>@<freq><,option=string> | |
| 41 | ||
| 42 | <driver> The video driver name, ignored by U-Boot | |
| 43 | <xres> The X resolution (in pixels) to use. | |
| 44 | <yres> The Y resolution (in pixels) to use. | |
| 45 | <depth> The color depth (in bits) to use. | |
| 46 | <freq> The frequency (in Hz) to use. | |
| 47 | <options> A comma-separated list of device-specific options | |
| 48 | ||
| 49 | Example: video-mode=fslfb:1280x1024-32@60,monitor=dvi |
