| Overview |
| ******** |
| |
| Google Icetower Development Board is a board created by Google for |
| fingerprint-related functionality development. |
| |
| Board has connectors for fingerprint sensors. Console is exposed over `μServo`_ |
| connector. MCU can be flashed using μServo or SWD. |
| |
| Hardware |
| ******** |
| |
| - STM32H7A3VIT6 LQFP100 package |
| |
| Pin Mapping |
| =========== |
| |
| Default Zephyr Peripheral Mapping: |
| ---------------------------------- |
| - USART_1 TX/RX : PA9/PA10 |
| - SPI_1 CS/CLK/MISO/MOSI : PA4/PA5/PA6/PA7 |
| - SPI_4 CS/CLK/MISO/MOSI : PE11/PE12/PE13/PE14 |
| |
| Programming and Debugging |
| ************************* |
| |
| .. zephyr:board-supported-runners:: |
| |
| Build application as usual for the ``google_icetower`` board, and flash |
| using μServo or an external J-Link connected to J4. If μServo is used, please |
| follow the `Chromium EC Flashing Documentation`_. |
| |
| Debugging |
| ========= |
| |
| Use SWD with a J-Link or ST-Link. Remember that SW2 must be set to CORESIGHT. |
