MicroPython Firmware for STM32H562RGT6 #16159
-
|
Hi everyone! I have a WeAct Studio STM32H562RGT6 Core Board, and I noticed there’s no official MicroPython support for this board. However, I see that there is support for the NUCLEO_H563ZI board. Both boards have a similar STM32H5 chip, with the main differences being memory size and connected peripherals. Is it possible to create a MicroPython firmware for the WeAct STM32H562RGT6 based on the existing support for the NUCLEO_H563ZI? If so, does anyone have instructions or suggestions on how to do this? For reference, here’s a link to the documentation and board specs for the WeAct STM32H562RGT6: WeAct Studio STM32H5 64Pin CoreBoard. Any advice or guidance would be greatly appreciated! |

You have to install the required tools, such as arm-none-eabi-gcc for cross-compiling ARM firmware. |

"Thank you for the reply! Installing arm-none-eabi-gcc and other tools for cross-compiling isn't an issue, but it seems like that alone might not be enough. Since the STM32H562RGT6 board has some differences from the NUCLEO_H563ZI (like memory size and peripheral connections), I think it may require adjusting configuration files, pin definitions, or other specifics to fully support the board. If you have experience creating or configuring MicroPython for new STM32 boards, I’d appreciate any additional guidance. I suspect modifications to files like mpconfigboard.h, pins.csv, or similar might be necessary, but I’m not entirely sure where to start." |

have you managed to build it already? I'm using it and can share you some of my build files if you want |

Hi! I haven't been able to build the firmware for this board yet. If you could share anything, I'd appreciate it! |

I'm sorry for the delay @robert-hh, but I haven't forgotten about those (3x H7 WeAct Studio) boards - I intend to revisit them after PyCon, this weekend. |

Hi Robert, Thank you for pointing me to the PR (#12540). Unfortunately, I'm having issues with compiling the firmware for the WEACT_STM32H743 board. Here's a summary of the problems I've encountered: Conflicting definitions: I ran into redefinition errors for HSE_VALUE, LSE_VALUE, and EXTERNAL_CLOCK_VALUE. These appear to be defined both in the stm32h7xx_hal_conf.h file (specific to the board) and in the stm32h7xx_ll_rcc.h file from the HAL library. I ensured all submodules were up to date using git submodule update --init --recursive, but the issue persists. I attempted to compile with both the commits in the PR: the one marked with a green check and the one with a red cross. Both resulted in similar errors. Thank you in advance for your time and assistance! |

I have built a firmware for a STM32H743 board with a STM32H743VIT6 chip. Attached are the .dfu and .hex files. It works and shows 8MB of flash and about 430kB head space. You can upload it to the board using dfu-util. Set the board to dfu-mode by pushing first the B0 button, then NR and then release both button. Call Edit: These are my board definition files: |

Hello friends, First of all, I want to sincerely thank everyone who has replied to me earlier — your help is truly appreciated. I'm still quite new to hardware configuration, and I must admit it's really difficult for me to get things right on the first try. I apologize if my questions seem too simple or naive. I'm working with the WeAct Studio STM32H562RGT6 board. Thanks to @AndreoBotelho, I already have a basic MicroPython board configuration that compiles successfully. However, it currently only enables two UARTs, while I critically need at least 5 UARTs for my project (ideally, all 6 supported by the MCU). Here is what I need working for my project: At least 5 UARTs (ideally 6), One SPI interface (used for other peripherals — not for SD card), SD card support (either via SPI or SDMMC), USB support, preferably with REPL. Everything else (I2C, ADC, PWM, etc.) is not needed and can be disabled. Could someone kindly guide me on how to configure the board to enable these interfaces? I assume I need to edit pins.csv, mpconfigboard.h, mpconfigboard.mk, or similar files — but I'm not sure where to start or how to properly define everything. I would be extremely grateful for any advice, examples, or working configurations! |

Just add all the uart pinout you need on the mpconfigboard.h file
// UART config
#define MICROPY_HW_UART1_TX (pin_A9) // SB23: ST-Link
#define MICROPY_HW_UART1_RX (pin_A10) // SB18: ST-Link
#define MICROPY_HW_UART6_TX (pin_C6)
#define MICROPY_HW_UART6_RX (pin_C7)

support my needs but you can change the settings you want on mpconfigboard.h

Use CUBE IDE to help you choose the uarts and pinout, this MCU has 8 UARTs |

WEACT_H562RG.zip I'm building MicroPython firmware for the WeAct Studio STM32H562RGT6 board. The firmware compiles and uploads successfully via DFU, but after reset: The USB (CDC) interface does not show up — the PC does not recognize the board. Confirmed working: Not working: Already done: In pins.csv: Other notes: Attached files: 🙏 I need help Thank you so much in advance for any insight! |
