I'm trying to use HAL_SPI_Abort() os SPI2 interface in DMA mode for STM32F769NI MCU and program hangs in it in loop: while (hspi->State != HAL_SPI_STATE_ABORT)So it seams that State should be changed in interrupts, I think that in SPI2_IRQn interrupt...
Hello,HAL contains both HAL_SRAM_Init and HAL_NOR_Init.But what if we have additional memory in PSRAM (FPGA device in our case).If we register the additional interface with HAL_SRAM_Init , it will call HAL_SRAM_MspInit again , and register again with...
Hello. I have custom board with STM32H743 and USB3320 in Full Speed Mode. Dont have problem with initialization of MSC (Window read descriptor, configuration and other). But when read blocks from SD card some trouble occurs. With USBPcam and Wireshar...
HiI use the STM32L452 which is configured as a USB CDC device using CubeMX. The device is used as a "gateway" that connects a linux host to a CAN bus system (essentially a USB-to-CAN adapter). The linux host configures the USB device as an SLCAN base...
Hello, everybody.I'm working in a circuit design whose main task should be to read an µSDHC card and copy its files to the computer. I'm using SMT32L073RZ with SPI (µSD to MCU) and full-speed USB (MCU to PC) communication interfaces.The other feature...
Posted on May 04, 2018 at 11:24Hi,I found a bug in the quad spi driver for stm32l4xx. In the function HAL_QSPI_Receive_IT, the interrupts flags must be cleared before start transfer otherwise flag TC could be missed:- WRITE_REG(hqspi->Instance->AR,...
Hi everybody,I created a project for using the STM32F746 DISCOVERY board with LwIP utility (see image 1 and Image 2). As soon as the project gets created i tried to build it, but ended up not beeing able to do so and getting the error shown in image...
I am using USB Virtual Com Port with CubeMX on a STM32F4 controller.The problem is, that occasionally, but increasingly often I cannot open the COM Port to my Device. It is very hard to reproduce, as changes in completely different code regions can c...
Hi ,I am using STM32L series of MCU.From the application code independent watchdog is used and when it is time for entering bootloader say due to firmware upgrade, i use while(1) to reset the system.1.Once inside bootloader I am observing that the bo...
Hi there,i have Projects where I used USB FS for COM Port Communication. How can i change them to USB HS do i need to change the clock or other settings?Thanks in advance.I am new with STM32
