Connections and IOs

The Nucleo F429ZI Board has 8 GPIO controllers. These controllers are responsible for pin muxing, input/output, pull-up, etc.

Available pins:

Nucleo F429ZI ZIO connectors (left) Nucleo F429ZI ZIO connectors (right) Nucleo F429ZI Morpho connectors (left) Nucleo F429ZI Morpho connectors (right)

For more details please refer to STM32 Nucleo-144 board User Manual.

Default Zephyr Peripheral Mapping:

The Nucleo F429ZI board features a ST Zio connector (extended Arduino Uno V3) and a ST morpho connector. Board is configured as follows

  • UART_3 TX/RX : PD8/PD9 (ST-Link Virtual Port Com)

  • UART_6 TX/RX : PG14/PG9 (Arduino Serial)

  • I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)

  • SPI1 NSS/SCK/MISO/MOSI : PD14/PA5/PA6/PA7 (Arduino SPI)

  • PWM_2_CH1 : PE13

  • ETH : PA1, PA2, PA7, PB13, PC1, PC4, PC5, PG11, PG13

  • USER_PB : PC13

  • LD1 : PB0

  • LD2 : PB7

  • LD3 : PB14

  • USB DM : PA11

  • USB DP : PA12

  • ADC1 : PA0

System Clock

The Nucleo F429ZI System Clock could be driven by an internal or external oscillator, as well as by the main PLL clock. By default System clock is driven by PLL clock at 180MHz, driven by an 8MHz high speed external clock.

Serial Port

The Nucleo F429ZI board has 8 UARTs. The Zephyr console output is assigned to UART3. Default settings are 115200 8N1.

Programming and Debugging

The Nucleo F429ZI board includes an ST-LINK/V2-1 embedded debug tool interface.

Flashing

The board is configured to be flashed using west STM32CubeProgrammer runner, so its installation is required.

Alternatively, OpenOCD or JLink can also be used to flash the board using the --runner (or -r) option:

$ west flash --runner openocd
$ west flash --runner jlink

Flash partitions for MCUBoot bootloader

The on-board STM32F429ZI MCU has 2MBs of internal flash memory. To use MCUboot, define a Zephyr partition table for the flash memory in its devicetree file nucleo_f429zi.dts. As a reference, a partition table for MCUBoot is already defined in the devicetree file, with these settings:

  • MCUBoot bootloader partition takes 64K bytes.

  • Zephyr settings partition takes 64K bytes.

  • Application image takes 256K bytes in Slot 0 partition.

  • Updating image takes another 256K bytes in Slot 1 partition.

  • A scratch partition with 128K is required for image swap.

A specific application can adjust each partition size based on its needs.
