| 157 | bool "Enable an early debug UART for debugging" |
| 158 | help |
| 159 | The debug UART is intended for use very early in U-Boot to debug |
| 160 | problems when an ICE or other debug mechanism is not available. |
| 161 | |
| 162 | To use it you should: |
| 163 | - Make sure your UART supports this interface |
| 164 | - Enable CONFIG_DEBUG_UART |
| 165 | - Enable the CONFIG for your UART to tell it to provide this interface |
| 166 | (e.g. CONFIG_DEBUG_UART_NS16550) |
| 167 | - Define the required settings as needed (see below) |
| 168 | - Call debug_uart_init() before use |
| 169 | - Call debug_uart_putc() to output a character |
| 170 | |
| 171 | Depending on your platform it may be possible to use this UART before |
| 172 | a stack is available. |
| 173 | |
| 174 | If your UART does not support this interface you can probably add |
| 175 | support quite easily. Remember that you cannot use driver model and |
| 176 | it is preferred to use no stack. |
| 177 | |
| 178 | You must not use this UART once driver model is working and the |
| 179 | serial drivers are up and running (done in serial_init()). Otherwise |
| 180 | the drivers may conflict and you will get strange output. |
