In the function:HAL_RTCEx_DisableBypassShadow()There is a cast to uint8_t in the line that resets the bithrtc->Instance->CR &= ((uint8_t)~RTC_CR_BYPSHAD);This causes the upper 24 bits of this configuration register to be cleared to 0s when called. Ev...
Hello,I'm trying out both the DMAs on the STM32H7S3L8. I am trying to keep it as simple as possible, so I am not using linked list mode (I think. CxLLR is 0). When using HPDMA, I get a Data Transfer Error when trying to copy from SRAM1 to DTCM. The d...
Hi, i have STM32F767 and im using FreeRTOS V2 and lwIP. Im facing known bug which should be fixed in FW_F7 V1.17 and im using FW_F7 V1.17.2 and still facing this. When i connect the ethernet cable, after 2 seconds FW is stuck at following place: I t...
Hello,I am working on stm32h7s78-dk board and I m running a simple LED toggle code in while loop. So, the MCU is getting stuck and my LED is blinking continuously. So, anyone has any solution for this please give your inputs on this. Thanks,
Hello everyone.I am following this project: https://github.com/viktorvano/STM32-Bootloader to create my own bootloader in a STM32H7, unfortunately the dual core of this device make the memory location a little bit tricky, is there any open project fo...
Currently, I am working on an STM32L432 microcontroller, emitting a 20 kHz sine wave. The code is relatively simple, although I am getting a slightly different frequency. I have been looking for solutions and found an embedded software package called...
How can I combine SD card and USB initialization in an STM32 project?Individually, both SD card and USB initialization work correctly. However, when combined, only the mount operation succeeds, and the process fails when opening a file. Testing each ...
Hi all,I know similar issues have been discussed before but I have not been able to find another post with the same issue. I am trying to use a CRC32 calculation to validate my flash memory, I am using KEIL IDE and the STM32L071CBT.This has been my c...
Hello,I want to use external SDRAM as the LTDC framebuffer with the STM32F746 microcontroller. I can write and read the desired data to/from the SDRAM without any issues. However, when I activate the LTDC, during the SDRAM initialization and config...
Hey there!Can we allocate the USB classes dynamically?Like, first we Initialize the USB Device stack, just register the CDC class and add its interface and start the USB Device Core (which pulls up the D+ line)This we need to do (atleast registering...
