| 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. |
