Other pins should be correctly placed, since we create the project from board selector.This will also allow use PH2/PH3 for QSPI.These signals are optional in full-duplex mode and not connected in default configuration.Relocate Ethernet CRS and COL signals from PH2/PH3 to PA0/PA3.This is required by FreeRTOS in order to call its functions from interrupt handler. Enable Ethernet interrupt and set preemption priority to 5.Enable Ethernet peripheral in pinout view in MII mode (MII used on the board).TIM6 is usually a good option, since it is a simple timer.In pinout/SYS configure different timebase than SysTick (recommended when using FreeRTOS).In clock tree configure 400MHz for core.In pinout/RCC configure HSE in bypass mode.Create new project in STM32CubeMX, select STM32H750-Discovery board and select "No" to "Initialize all peripherals in default mode?" pop-up.You might also need to check board solder bridges to make sure the Ethernet is connected to MCU. The main differences are usually pinout and clock configuration. Send UDP message periodically (optional)Īlthough the example is using STM32H750-Discovery, it might be easy to use the same steps for other STM32H7 based boards.Configure FreeRTOS and LwIP middlewares correctly.Configure project in STM32CubeMX for STM32H750-Discovery.
#Stm32h723 nucleo code#
There is minimum code added on top of STM32CubeMX and HAL libraries, this code is provided AS-IS. So the same licenses apply to the these examples. Libraries and middleware is taken from STM32CubeH7 package. When changing memory layout, the MPU configuration needs to be updated accordingly. Value provided here are an example implementation, other configurations are also possible in order to optimize memory usage. The LwIP heap is reduced to fit the rest of D2 RAM together with DMA descriptors. The RX buffers need to be placed in AXI SRAM, since they won't fit to D2 RAM, together with LwIP heap. Variableįor STM32H72x/H73x devices, the D2 SRAM is more limited (only 32kB). On single core devices this part can be used for other purposes. On STM32H74x/H75x devices, all data related to Ethernet and LwIP are placed in D2 SRAM memory (288kB).įirst 128kB of this memory are reserved for Cortex-M4 on dual-core devices. Using GIT tags it should be easy to find examples for particular version of STM32CubeIDE and HAL library TCP/IP configuration in LwIPīelow configuration is necessary to achieve good TCP/IP performance Parameter Initial release on ST community (with minor changes on Github) Added iperf measurement and TCP/IP settings tuned.
#Stm32h723 nucleo driver#
Ethernet driver reworked in new library release. Changes in code can be find by searching for ETH_CODE keyword.Code should work even when re-generating the code in STM32CubeMX.
#Stm32h723 nucleo how to#
The same how to step-by-step is also provided below Features
These examples are provided to accompany the FAQ article on ST community. Simple Ethernet examples based on LwIP and FreeRTOS, running on ST Nucleo and Discovery boards. For older tool versions please see older version of this readme in the repository This readme is intended for STM32CubeIDE version 1.9.0 and STM32CubeH7 version 1.10.0.
