173------------
174
175The Nucleo F429ZI System Clock could be driven by an internal or external oscillator,
176as well as by the main PLL clock. By default System clock is driven by PLL clock at 180MHz,
177driven by an 8MHz high speed external clock.
178
179Serial Port
180-----------
181
182The Nucleo F429ZI board has 8 UARTs. The Zephyr console output is assigned to UART3.
183Default settings are 115200 8N1.
184
185
186Programming and Debugging
187*************************
188
189The Nucleo F429ZI board includes an ST-LINK/V2-1 embedded debug tool interface.
190This interface is supported by the openocd version included in Zephyr SDK.
191
192Flash partitions for MCUBoot bootloader
193***************************************
194
195The on-board STM32F429ZI MCU has 2MBs of internal flash memory. To use `MCUboot`_,
196define a :ref:`Zephyr partition table <flash_map_api>` for the flash memory in
197its devicetree file ``nucleo_f429zi.dts``. As a reference, a partition table for
198MCUBoot is already defined in the devicetree file, with these settings:
199
200- `MCUBoot`_ bootloader partition takes 64K bytes.
201- Zephyr settings partition takes 64K bytes.
202- Application image takes 256K bytes in Slot 0 partition.
203- Updating image takes another 256K bytes in Slot 1 partition.
204- A scratch partition with 128K is required for image swap.
205
206A specific application can adjust each partition size based on its needs.
