| |
| Pin Mapping |
| =========== |
| |
| The SAM E54 Xplained Pro evaluation kit has 4 GPIO controllers. These |
| controllers are responsible for pin muxing, input/output, pull-up, etc. |
| |
| For more details please refer to `SAM D5x/E5x Family Datasheet`_ and the `SAM E54 |
| Xplained Pro Schematic`_. |

| System Clock |
| ============ |
| |
| The SAME54 MCU is configured to use the 32.768 kHz external oscillator |
| with the on-chip PLL generating the 48 MHz system clock. |
| |
| Serial Port |
| =========== |
| |
| The SAME54 MCU has 8 SERCOM based USARTs with one configured as USARTs in |
| this BSP. SERCOM2 is the default Zephyr console. |
| |
| - SERCOM2 115200 8n1 connected to the onboard Atmel Embedded Debugger (EDBG) |
| |
| PWM |
| === |
| |
| The SAME54 MCU has 5 TCC based PWM units with up to 6 outputs each and a period |
| of 24 bits or 16 bits. If :code:`CONFIG_PWM_SAM0_TCC` is enabled then LED0 is |
| driven by TCC0 instead of by GPIO. |
| |
| SPI Port |
| ======== |
| |
| The SAME54 MCU has 8 SERCOM based SPIs. |
| |
| I2C Port |
| ======== |
| |
| The SAME54 MCU has 8 SERCOM based I2Cs. On the SAM E54 Xplained Pro, |
| SERCOM7 is connected to a AT24MAC402 EEPROM and a ATECC508A Crypto |
| Authentication device. |
| |
| Programming and Debugging |
| ************************* |
| |
| The SAM E54 Xplained Pro comes with a Atmel Embedded Debugger (EDBG). This |
| provides a debug interface to the SAME54 chip and is supported by |
| OpenOCD. |
| |
| Flashing |
| ======== |
| |
| #. Build the Zephyr kernel and the ``hello_world`` sample application: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: atsame54_xpro |
| :goals: build |
| :compact: |
| |
| #. Connect the SAM E54 Xplained Pro to your host computer using the USB debug |
| port. |
| |
| #. Run your favorite terminal program to listen for output. Under Linux the |
| terminal should be :code:`/dev/ttyACM0`. For example: |
| |
| .. code-block:: console |
| |
| $ minicom -D /dev/ttyACM0 -o |
| |
| The -o option tells minicom not to send the modem initialization |
| string. Connection should be configured as follows: |
| |
| - Speed: 115200 |
| - Data: 8 bits |
| - Parity: None |
| - Stop bits: 1 |
| |
| #. To flash an image: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: atsame54_xpro |
| :goals: flash |
| :compact: |
| |
| You should see "Hello World! atsame54_xpro" in your terminal. |
