U-Boot on LCD monitor (BeagleBoard)?

Hello everybody,

just a question - Is it possible to interact with the U-Boot command line (prompt) over an LCD monitor?

I'm using a Beagleboard rev C4 with DVI-D/HDMI and Beagletouch hardware. It would be nice to interact directly with the bootloader.

As it is now, on boot, I get only an Orange/yellow gradient background on my LCD.

Is it really only possible over serial and usb connection, like someone other told me?

Thanks
Giorgio

No, this is not possible. A LCD monitor is an output device, and to enter commands to the command line interface you need an input device.

As of now, there is no graphics support for OMAP processors in U-Boot mainline, so you don't even get output.

With current mainline code, yes.

Best regards,
