32F417: How to block USB_FS ISR from a shared resource (serial FLASH, on SPI)

I have a serial FLASH, a part of which implements a Windows file system (removable block device). Another part of the FLASH is for data logging etc usage.All this is working, but the ISR which implements the USB block device must be blocked out of th...

STSAFE-A crypto chip using X-cube/mbedTLS library example for microprocessor(arm)

Hi Everyone,We are using STSAFE-A110 chip for secure boot and secure firmware update for STM32G4 MCU, same we need to do for microprocessor(ARM7), we gone through the OpenSSL example provided by ST, we need STSAFE-A crypto chip using X-cube/mbedTLS l...

I am trying to run STSAFE wrap unwrap example with STM32G484E-EVL but get the following error. I had also included STM32G4 lib files. I am stuck at this point. How should I resolve this error????? Any solution????

Hello everyone I have download the X-CUBE-SAFEA1 Software Package for STSAFE-A software in that sample code is given only for STM32L476RG-nucleo. Can I get sample code for STM32484E-EVL?????

Hi,I am using the STM32H757(master) to load code into flash of another STM32H757(slave). The slave is in bootloader mode ( SPI ). Question 1: Does somebody has a driver for the master side to read/write into slave, especialy option bytes? Thank you

HAL_I2C_Master_Transmit_DMA sends only one byte

Define error in stm32l4xx_hal_exti.h

Hi everybody,I think I found a bug in stm32l4xx_hal_exti.h at the definition of the GPIO-ports:#define EXTI_GPIOA 0x00000000u#define EXTI_GPIOB 0x00000001u#define EXTI_GPIOC 0x00000002u#define EXTI_GPIOD 0x00000003u#define EXTI_GPIOE 0x00000004u#defi...

Foreground interrupts are hanged for sometime (more than 800 milli seconds)while erasing the bank2 with "(HAL_FLASHEx_Erase_IT(&eraseInitStruct) != HAL_OK)" function call in STM32H743.

if we test with ( HAL_FLASHEx_Erase(&eraseInitStruct, &SECTORError) != HAL_OK) function there is no impact on foreground interrupts. But per design notes of dual bank concepts there should not be any hang/impact on first bank operation when we erase/...
