STM32 MCUs Embedded software

Hello, I try to start with azure RTOS on a H723ZG and when looking at the examples (e.g. TCP-Client) it is completely different from code generated through CubeIDE from scratch. I hoped that generated code will be a working framework that I adjust/add.

CubeIDE makes a completely different file structure, some includes cannot be found "VOID" is written capital and causes an error, etc. I am completely new to RTOS, I did some bare metal HAL with CubeIDE and that worked quite well, but just started re...

The symbol FLASH_OPTR_DBANK is used as an option and a register bit def

The symbol FLASH_OPTR_DBANK is used to determine the dual bank configuration in stm32g4xx_hal_flash.h, but it is also used for a register bit for the dual bank configuration (CMSIS). If this arrangement is correct, the G4 HAL library can not handle s...

Resolved! Having trouble booting from Bank2 and jumping to Bank1 on STM32G474

Hello,I'm working on an a project that uses an ST32G474, and it needs to run two different/independent applications. The project requires that from a reset, the device boots from Bank2 every time. The application in Bank2 will then decide if it is ...

Is it possible to flash firmware via RS485 between two ST chips

Hello everyone,For a project i would like to flash firmware from 1 chip via another chip. So now my question is whether this is possible because in the application note AN2606 they say that this is possible via RS232 for certain chips. Is this also p...

How to get the L496G-CELL02 cellular MQTT example working?

I downloaded the en.x-cube-cellular.zip and unziped the folder STM32CubeExpansion_CELLULAR_V5.2.0.I imported the STM32CubeExpansion_CELLULAR_V5.2.0\Projects\STM32L496G_Discovery\Demonstrations\Cellular\IDE\STM32CubeIDE\DiscoL496_RD_BG96v2_STMOD proj...

How to get the B-L462E-CELL1 cellular MQTT example working?

I downloaded the en.x-cube-cellular.zip and unziped the folder STM32CubeExpansion_CELLULAR_V5.2.0. I then installed the changes to upgrade to V5.2.1.I imported the project into CubeIDE and found the MQTT sample was not imported. I then tried to follo...

Bug with code generation when using HAL and Ethernet (+ workaround)

I've created a new project using HAL for the NUCLEO-F207ZG with CubeMX that ships within CubeIDE (1.5.0). After implementing a minimal network stack from scratch that supported the bare minimum of ARP, IP and ICMP to ping my board, I was wondering wh...

USB MSC in with Internal flash

There are many threads about using internal flash as MAss Storage in the USB Mass Storage Class, but non of them ever lead to anything.Has anyone actually managed to get it working and is willing to share their code? I have scraped the internet for a...

Can the STM32H743 OTG_HS2 USB configured as Host FS mode transmit at 12 Mbps?

I have a custom board with an STM32H743ZIT6 on it. Configuring the OTG_HS2 controller with STM32CubeMx and STM32Cube_FW_H7_V1.9.0 as a USB Host and MSC, I can read a USB memory stick.The question is: my oscilloscope shows the DM and DP lines being cl...

Using USB 2.0 in Type C connector

Hi, We are designing a USB 2.0 interface between STM32H750IB and PC.PC will be acting as Host and STM32H750IB will be acting as Device.But for some reasons like future upgradability, we are using USB Type-C Connector.Note that we are going to use USB...
