STM32H7A3 flash CR register incorrectly defined in SVD and source

Specifically the SNB (SSN1 & SSN2 in the data sheet) bits are defined erroneously as being 3 bits wide at position 6, whereas it should be 7 bits wide, allowing all 128 sectors in each bank to be erased.#define FLASH_CR_SNB_Pos (6...

STOP2 mode and FreeRTOS

HiI want to use FreeRTOS with low power STOP2 mode without using the ticklessidle mode.One of the tasks once every cycle goes sets the mcu into stop2 mode.I’m using both RTC and LPUART for waking up the mcu.when using with just two FreeRTOS tasks all...

STM32U5/B-U585I-IOT02A define my own secure function with TF-M

Hello,I am using the X-AZURE-CUBE example that integrates Azure RTOS with TF-M. I would like to define a function in the secure part to be called from the non-secure part. Following the SBSFU example I created a .c file in /Secure/Src, defined the .h...

Do I need to configure USB FS with the STM32CubeMX tool in the STM32CubeIDE for the built-in DFU bootloader to work?

I am using the STM32G474RE and according to AN2606 Rev 55, it has a built-in bootloader in system memory. I set the option bytes such that the MCU boots from system memory and I will use the STM32Cubeprorammer CLI to program via USB. In my applicatio...

How can I find a sample that read ADC with SPI at 1K speed and send data by USB to PC?

Hi all,I'm study STM32F103 now, I have a application:

Transmit data through CDC VCP Failed error

I am trying transmit data using CDC(virtual port) in NUCLEO-H743Zi2, but I am getting this error when I plug in my VCP port to my pc (Unknown USB Device (Device Descriptor Request Failed)), I could not find a way to fix it.My hardware settings:MCU sp...

Is it states somewhere how fast the bootloader starts (min/max time)?

Is the bootloader start up time defined somewhere? I'm using an STM32F429. I tested and it takes about 6ms. But is it states somewhere (min/max times)?
