How to add FreeRTOS to BLE Serial Port Example?

I refer to the BLE Beacon FreeRTOS example and include the FreeRTOS file into the BLE Serial Port example, but the RAM exceeds 1808 Byte, so I modified FreeRTOSConfig.h and adjusted the constants related to SIZE, but it still failed.I would like to a...

SPI_RxFIFOThresholdConfig is not defined

I'm using the L4xx HAL library and trying to set my SPI RX threshold value to 1/4 so I can receive a single byte response. From my research there should be a HAL function called SPI_RxFIFOThresholdConfig that will do this. When I put it into my SPI i...

How to share variable between bootloader and application without overwriting

Good morning,I have a problem sharing a variable between bootloader and application into my STM32F303ret6 uC. I need to write a shared variable to tell the bootloader that it has to wait for new firmware.I read many posts which suggest to declare a v...

If I allocate USB peripherals to M7 core along with SPI, memory interfaces, will M.7 core ses performance bottleneck?

STM32H750; Ethernet; open new Socket; to connect to another embedded device.

I need to establish an Ethernet connection between two embedded devices. From a PC I can connect to my application or to the other device and exchange messages. How do I do this on my H750. How do I open a connection from my device if the IP and port...

STM32L4 USB-enabled dev board not appearing on computer

Hello, I have a STM32 Nucleo-64 development board with the STM32L476RG MCU on it.. I have made a small PCB that, among other things, brings the USB interface to a connector. I have implemented a simple USB configuration following some online tutorial...

Ethernet TX doesn't work because ETH_DMATxDescListInit() doesn't initialize the entire ETH_DMADescTypeDef

The officially recommended recipe for lwIP on STM32H7 puts the ethernet DMA descriptors in SRAM1. SRAM1 is not zero'd by the default startup code.It's unsafe for the network drivers to assume that buffers and critical data structures live in .bss.F...
