I am sorry, I can not understand the question.
U-boot always outputs to serial port.
If you would like to change to another serial port look at the
configuration file corresponding to your board under include/configs.

[U-Boot-Users] How console redirection is done

[yasosyaso]

Hi Ori,

thank you for your reply.
Actually how the console redirection is done in the uboot, ie., how it is
implemented in the code.
In which file of Uboot the module that will do console redirection is
present ?

That's not exactly true. After the initial console (bootup) you can use more 
than serial.

There are a few functions like drv_lcd_init in lcd.c that create a device_t 
structure -- in my version they're all called within devices_init in 
common/devices.c during boot. This defines a putc, puts, getc, and tstc to 
handle I/O character by character. Once you call device_register() it will 
available to the system. Using the environment variables stdin, stdout, and 
stderr you can choose which device is active, and console.c calls the 
appropriate function pointer. Set the variable and you can be printing on 
the LCD instead.

Of course all this can be changed with a million CONFIG_ parameters, and it 
is a little strange if you have several consoles available and no default.

[U-Boot-Users] How console redirection is done

[yasosyaso]

Actually here I want to do console redirection through USB port.

To do that first I want to know how serial console redirection is done in
the UBOOT code.
i.e., how in uboot the "serial console redirection" is implemented.

For console redirection there should be some code, somewhere in the UBoot.
I want to know how and where(in file,in which function) the console
redirection is implemented.
[I have found how the configuration is done for console redirection]

Thanks
yaso
