Introduction

The STM32F429zi incorporate the Arm®Cortex®-M4 32-bit RISC CPU with up to 48MHz. The STM32F429zi is capable as an application controller for the iRJ45/SoM module.

The port for STM32F429zi bases on ST’s HAL Layers. Thus porting to any other ST hardware is very easy. See here for additional information: STM32 (uGOAL) .

Software

Toolchain

For compiling the example code, the GNU Arm Embedded Toolchain is required. It can be obtained in several ways. Further information can be found here: https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads.

Make sure, the toolchain is added properly to your path variable after the installation.

Building

Within a example folder (e.g. projects/ugoal/02_profinet/gcc) of the software delivery build the firmware with following commands:

# build for STM32F429zi make PLATFORM=STM32F429zi clean all

Flashing

Flashing the firmware is done with the following command. Please use the UART device for your system.

make PLATFORM=STM32F429zi UART=/dev/tty.ACM0 flash serial

The Makefile target serial will use minterm.py from the pyserial package. Thus python and pyserial needs to be installed.

Or you could just copy the created *.bin to the STM32, which appears as Mass Data Storage in your computer.

Getting Started

Preparations

Hardware Requirements

Arduino PMOD Adaptershield

Make sure following settings are set:

J13: Connect “VCC33_Sockel” with “VCC33_RJ45”

J8: Connect “CS” with “PB2”

J7: Connect “RST” with “PD7”

All DIP-Switches to OFF

STM32F429I-Nucleo board

Make sure following settings are set:

JP6: Remove this Jumper on the front side of the board

Due to a double assignment of pins the simultaneous use of SPI and Ethernet is not possible with STM32 Nucleo-144. The JP6 jumper activates Ethernet.

Target System

Please connect both boards with each other, before you connect them per USB to your computer.

There is no further configuration required.

Debugging

UART

The STM32F429zi provides an UART over USB cable. Choose the following settings:

Speed

115200

Data Bits

8

Stop Bits

1

Parity

None

Flow Control

None

Application 02_profinet

The available applications are described here. Following you’ll find an example. After setting up the serial monitor and starting the debug session, the output should look like this:

[INF] ../rpc/goal_mctc_rb.c:277 creating rpc ring buffer with buffer size 768 and elem size 256 [INF] ../rpc/goal_mctc_rb.c:277 creating rpc ring buffer with buffer size 768 and elem size 256 [INF] ../goal_media/goal_mi_mctc.c:793 rpc transfer size set to 1024 [INF] ../goal_media/goal_mi_mctc.c:723 peer requested Sync Init [INF] ../goal_media/goal_mi_mctc.c:723 peer requested Sync Init [INF] ../goal_media/goal_mi_mctc.c:723 peer requested Sync Init [INF] ../goal_media/goal_mi_mctc.c:723 peer requested Sync Init [INF] ../goal_media/goal_mi_mctc.c:455 RPC state synchronized, running appl_setup [INF] ../goal_media/goal_mi_mctc.c:458 configuring timeout values for peer [INF] ../pnio/goal_pnio_rpc_ac.c:259 PROFINET Application Core successfully started [INF] ../example/02_profinet/goal_appl.c:188 Initializing device structure [INF] ../example/02_profinet/goal_appl.c:230 PROFINET ready [INF] ../goal_media/goal_mi_mctc.c:487 local setup done [INF] ../ugoal/ugoal.c:212 HEAP utilization: 3400/4096 (83%).
