[U-Boot] USB serial console under Uboot
Hello,
I have one system with USB connector only, no RS232 port. How can I do the interaction with Uboot?
Thanks for your help,
Mike

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.

Sorry...I thought this on an OMAP3 list and not u-boot. Looking at the wrong mailing list!

I do have a USB-RS232 cable. I am using MPC8549 as processor. Would you please let me know more details on the usbtty?

That's because the driver is in drivers/serial/usbtty.c now.
Best regards,

I found it in U-boot-1.3.4 under /drivers/serial directory. Anyone has document on the setup?
Thanks,
