Linux/AM5748: using only usbtty for u-boot and Linux

Tool/software: Linux

Hi Team,

Is it possible to configure u-boot and the Linux kernel to only use usbtty for status output and as console?

On the EVMs there is usually a UART-to-USB device, but I have a customer who directly connect to USB.

Thanks,
  Robert

    Robert,

    U-Boot usb stack doesn't implement usb-serial gadget function, so this cannot be done in U-Boot.

    I think you can use usbtty for Linux console, I just never used it. This forum has many threads which discuss how to change Linux console to different UART, the procedure should apply to usbtty too.
