For imx devices...
Is it possible to bring up Uboot and use the USB device connector to act as a virtual serial port? Or is it always necessary to use the RS232 (then a USB-2-Serial adapter).
I know it's possible to use USB as a virtual COM port once the kernel is running. But I'd like to be able to do this in Uboot and not have to use a usb-2-serial adapter with my laptop.

USB serial driver is not supported in uboot.
The debug message is sent to the uart port.
