Cortex-M3 NVIC config with FreeRTOS

I'm working on a legacy projected using FreeRTOS v7.3.0 on an STM32F205 Cortex-M3.My system intermittently lands in the hard fault exception handler, and/or watchdog resets.I have tracked down some issues with the NVIC config:Using NVIC_PriorityGroup...

Can Fast Enable be configured in One-Pulse mode using HAL?

In OC mode, Fast Enable can be configured through the OCFastMode field of the TIM_OC_InitTypeDef structure. But the TIM_OnePulse_InitTypeDef structure doesn't have an OCFastMode field. Does this mean Fast Enable can't be set for channels in One-Pulse...

Got FR_INT_ERR when running f_read() in Project FatFS_uSD_Standalone

Hello,I am using NUCLEO-H743ZI2 and running the project FatFS_uSD_Standalone with AdaFruit microSD. The TFT_ShieldDetect() is commented out because there is no LCD. The STM32.txt is successfully created and the text is successfully written into the f...

After Enabling FreeRTOS USART Baudrate Drops Down

I'm trying to learn RTOS on STM32F407VG(Discovery Board). I am able to use the USART without FreeRTOS at 115200 baud rate. Nevertheless, when I enable FreeRTOS and try to send basic strings with the same USART settings(115200 baud rate etc.), I can n...

Is it possible to just change the driver's DeviceName without re-signing

CubeProgrammer setup already provides signed DFU driver with the inf file containing the below information:DeviceName = "STM32 Bootloader" VendorName = "STMicroelectronics" SourceName = "DFU Install Disk" DeviceID = "VID_0483&PID_DF11" DeviceGUID =...

How to Use BSP Library for Audio Recording?

I'd like to create a program by which I can record and listen sound by using my board, STM32F746G-Disco. I'd like to use BSP library, however, I have some questions.When I looked at the stm32746g_discovery_audio.c file, I saw that there are 2 global ...

How do I reset the internal USB state machine correctly when something USB-related goes wrong?

I'm working with the Nucleo-64 development board with an STM32L476 microcontroller and I'm using the USB source code that STM32CubeMX has generated for me. Every once in a while something unpredictable happens, e.g. the user unplugs the USB-cable in ...
