48 bool "Enable an early debug UART for debugging"
49 help
50 The debug UART is intended for use very early in U-Boot to debug
51 problems when an ICE or other debug mechanism is not available.
52
53 To use it you should:
54 - Make sure your UART supports this interface
55 - Enable CONFIG_DEBUG_UART
56 - Enable the CONFIG for your UART to tell it to provide this interface
57 (e.g. CONFIG_DEBUG_UART_NS16550)
58 - Define the required settings as needed (see below)
59 - Call debug_uart_init() before use
60 - Call debug_uart_putc() to output a character
61
62 Depending on your platform it may be possible to use this UART before
63 a stack is available.
64
65 If your UART does not support this interface you can probably add
66 support quite easily. Remember that you cannot use driver model and
67 it is preferred to use no stack.
68
69 You must not use this UART once driver model is working and the
70 serial drivers are up and running (done in serial_init()). Otherwise
71 the drivers may conflict and you will get strange output.
