| :name: IPM on NXP LPC |
| :relevant-api: ipm_interface |
| |
| Implement inter-processor mailbox (IPM) on NXP LPC family. |
| |
| Overview |
| ******** |
| |
| Some NXP microcontrollers from LPC family are dual-core, this |
| sample application uses a mailbox to send messages from one |
| processor core to the other. |
| |
| This sample applies to the following boards: |
| - :ref:`lpcxpresso54114`, two core processors (Cortex-M4F and Cortex-M0+) |
| - :ref:`lpcxpresso55s69`, two core processors (dual Cortex-M33) |
| |
| Requirements |
| ************ |
| |
| - :ref:`lpcxpresso54114` board |
| - :ref:`lpcxpresso55s69` board |

| Running |
| ******* |
| Open a serial terminal (minicom, putty, etc.) and connect the board with the |
| following settings: |
| |
| - Speed: 115200 |
| - Data: 8 bits |
| - Parity: None |
| - Stop bits: 1 |
| |
| Reset the board and the following message will appear on the corresponding |
| serial port: |
