Hello,
I have one system with USB connector only, no RS232 port. How can I do the interaction with Uboot?
You can start by providing much more detail. I don't know if there's USB console support in U-boot, but if so I'm sure it's hardware dependent.
There is usbtty support in u-boot but only for some OMAP1 devices (although it is broken in the current release) and for some MPC devices. Unfortunately, I don't believe that this is currently supported for OMAP3. Therefore, I think that you are going to need an RS232-to-USB dongle for your PC in order to interact with u-boot.
Cheers Jon
