Is there a bug in the SVD file for the STM32G431? It appears to list ADC12_Common->CCR as being at address 0x50000208 when it supposed to be at 0x50000308

Device descriptor failed error for composite USB class(MSC+CustomHID)

Hello,I want to implement USB composite class of MSC + CustomHID on STM32LRR5ZI development board. I created a library file for the same by combining functionalities of both the class. But PC is unable to recognize the USB device connected to it. Can...

IAP application with STM32CubeIDE/ STLink

Hi everyone,I'm following the LWIP_IAP application in STM32756G_EVAL 's Repository. The bootloader work fine, but I don't know how to config the application firmware to boot from a specify address flash.Is this the right way to config flash memory o...

AWS IoT Core Connection

Hi, I'm looking to connect a STM32H7 board to iot core, simple stuff: publish and subscribe to topics.I found x-cube-aws but i don't know how it works (I read the getting started guide but no success).In the aws documentation for freertos i didn't fo...

i am using stm32f103xE MCU. i am using FATFS with SDIO. it's opening the file, but when i am writing the data to the file it's giving the FR_INVALID_OBJECT Error.

char data[] = "Testing File";if(f_mount(&fs, SD_Path, 0) == FR_OK) { if(f_open(&myFile, "Test_File.txt", FA_WRITE | FA_CREATE_ALWAYS) == FR_OK) { if(f_write(&myFile, data, sizeof(data), &myBytes) == FR_OK) { f_close(&myFile); } f_clo...

freeRTOS in STM32Cube_FW_H7_V1.6.0 on NUCLEO-H745ZI-Q

I am working on a project based on freeRTOS in STMCube_FW_H7_V1.6.0 and NUCLEO-H746ZI-Q.When I compiles a CM7 code of the project, the port.c and the portmacro.h in ARM_CM4F (not in ARM_CM7) are used. (I am using MDK-ARM compiler 5.)Are there no prob...

I have found a mistakes on stm32h750 svd file in section DFSDM. Many of registers have other address as real. Is possible to obtain svd file with right addresses? Thank you.

Resolved! STM32F7: USBH_malloc fails (despite 8 KB heap)

In my project, which uses FatFs and a couple of peripherals, I always used a heap size of 0x100 bytes, with no apparent problems.After activating the USB Host for HID Class, I increased the heap size to 0x2000 bytes (8 KB), but still the USBH_malloc ...

Interdependence of LL and HAL => annoying => wish list

I cannot use HAL because this library is not authorized by the company for the type of development I am doing. But I can use CMSIS and LL.When I compile ***_ ll_.c files some include stm32h7_hal.c, which itself includes stm32h7xx_hal_conf.h. These fi...

Resolved! STM32F031K6 Bootloader Write Memory Command Failure (No ACK or NACK)

Hi,I'm trying to utilise the built-in UART bootloader in the STM32F031K6 to perform firmware update. I've read the AN3155 and AN2606 documentation but unfortunately, I'm out of luck so far when trying to write the firmware via the bootloader to the t...
