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

| input will be fed into the UART. This allows you to interact with |
| U-Boot. |

| flag. In raw mode, U-Boot sees all characters from the terminal |
| before they are processed, including Ctrl-C. In cooked mode, Ctrl-C |
| is processed by the terminal, and terminates U-Boot. Valid options |
| are: |
| |
| -t raw-with-sigs Raw mode, Ctrl-C will terminate U-Boot |
| -t raw Raw mode, Ctrl-C is processed by U-Boot |
