USB support in U-Boot?

GoogleGroups

Hello,

I was trying with custom build u-boot for beagleboard.
But it seems that support for USB has not been compiled-in by default (as there is no command related to USB).

Basically I want my USB stick to get detected in U-Boot (not in kernel).
Does anybody has tried with enabling support for USB in u-boot? There are some macros in the code that needs to be defined, but which one i am not sure.

Please ,if possible, put some light on this.

There is no OMAP3 USB support in U-Boot mainline. There are some patches floating around, but they are not applied yet:

Most probably they won't help you accessing an USB stick, though, as they are USB tty only (?). Why do you need to detect an USB stick in U-Boot?

Best regards

Thanks, for the info.
I intended to learn USB functionality and thought learning USB functionality through U-Boot would probably be easier as their would be bare minimum support for USB driver in u-boot.
