I don't know if there's USB console support in U-boot, but if so I'm sure it's hardware dependent. regards, Ben ^ permalink raw reply [flat|nested] 8+ messages in thread

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.

Sorry...I thought this on an OMAP3 list and not u-boot. Looking at the wrong mailing list! Cheers Jon ^ permalink raw reply [flat|nested] 8+ messages in thread
