I created a project to create, write, read and close a file in a USB stick, using a STM32F413 MCU. I used STM32CubeMX to generate the code. The relevant part of the code is this: uint8_t text[]={"Hello world\r\n"},rbuff[50],test=0;   switch(Appli_sta...

I'm trying to create and write a file in a USB stick as a USB MSC Host + FatFs using FreeRTOS my MCU is a STM32F413I'm using the code generated by STM32CubeMX and added the following functions:f_mount(&USBHFatFS, (TCHAR const*)USBHPath, 1));f_open(&U...

I have an issue with SPI in bidirectional mode (MOSI, CLK and CS). I have a device which I need to write to and from. When I have to write to an adress in the slave device, it works perfectly: reg=0x04; CS_DRIVER_LOW c=HAL_SPI_Transmit_DMA(&hspi2,...

I'm working on a custom board with a BLUENRG-2. I'm able to flash and erase with the UART and the SWD pins, but none of the programs work. When I debug it step by step, I find out that all programs hang on this line, when it writes on the BLUE_CTRL r...

I am testing a custom board trying to use BLUENRG-1 as a coprocessor, but when I flash the chip (using Keil, Atollic or BlueNRG-1 ST-Link Utility) with ST-Link/V2 tool, with the SWD port, the chip locks and I am unable to access the chip again, regar...
