103 bool "Enable an early debug UART for debugging"
104 help
105 The debug UART is intended for use very early in U-Boot to debug
106 problems when an ICE or other debug mechanism is not available.
107
108 To use it you should:
109 - Make sure your UART supports this interface
110 - Enable CONFIG_DEBUG_UART
111 - Enable the CONFIG for your UART to tell it to provide this interface
112 (e.g. CONFIG_DEBUG_UART_NS16550)
113 - Define the required settings as needed (see below)
114 - Call debug_uart_init() before use
115 - Call debug_uart_putc() to output a character
116
117 Depending on your platform it may be possible to use this UART before
118 a stack is available.
119
120 If your UART does not support this interface you can probably add
121 support quite easily. Remember that you cannot use driver model and
122 it is preferred to use no stack.
123
124 You must not use this UART once driver model is working and the
125 serial drivers are up and running (done in serial_init()). Otherwise
126 the drivers may conflict and you will get strange output.

463 Select this to enable a seral UART for sandbox. This is required to
464 operate correctly, otherwise you will see no serial output from
465 sandbox. The emulated UART will display to the console and console
466 input will be fed into the UART. This allows you to interact with
467 U-Boot.
468
469 The operation of the console is controlled by the -t command-line
470 flag. In raw mode, U-Boot sees all characters from the terminal
471 before they are processed, including Ctrl-C. In cooked mode, Ctrl-C
472 is processed by the terminal, and terminates U-Boot. Valid options
473 are:
474
475 -t raw-with-sigs Raw mode, Ctrl-C will terminate U-Boot
476 -t raw Raw mode, Ctrl-C is processed by U-Boot
477 -t cooked Cooked mode, Ctrl-C terminates
