With BFB2 set on an STM32F429 (i.e. the ROM bootloader runs before the application code) it is not possible to start an application that runs from the flash alias at address 0. That works fine with BFB2=0.

STM32F429.The problem appears after the bootloader has run and jumped to application code, which it does when BFB2=1. When my application reads data from addresses around 0, it gets data from the ROM bootloader instead of from flash. I.e. it behaves ...

STM32G07 bootloader not starting

I had a hard time the last days struggling with STM32G07 bootloader.Finally I came to this conclusion:I have option bit nBOOT_SEL cleared (unckecked in STCubePorgrammer) and even though this bit is long cleared ie several power cycles have been done ...

Change parity on UART using LL API during runtime / after init

I need to change the UART parity from a FREERTOS task. I also use interrupt per byte received.Do I need to disable UART and interrupt before changing the parity?I use LL API. So what I do so far:initialized_ = false; // Set initialized to false so in...

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?
