Hi, after flashing the MCU, it jumps to an incorrect system memory address instead of my application code. I looked into the issue and found that the vector table isn't properly set in flash. I'm trying to understand how to set it correctly, but I'm ...
Hello,after setup SPI1 and setting CSTART=1, I expected that SPI is send immidiatly on bus.(I toogled PE00 with CSTART=1)I couldn't find some that explains that behaviour. It behave the same, if I use DMA or writing directly to TXDR.Do you have an i...
Split from old thread: https://community.st.com/t5/stm32-mcus-security/information-about-mcuboot-and-illustrative-examples/td-p/689154 Hello @Jocelyn RICARD ,I'm looking for guidance on integrating Mcuboot into my project. I am using a NUCLEO-U5A5ZJ-...
Hello. I bought Riverdi board and start to develop my code. I found in FREERTOS_M7 Config parameters RTOS CHECK_FOR_STACK_OVERFLOW. Documentation says CHECK_FOR_STACK_OVERFLOWParameter Description:FreeRTOS provides two optional mechanisms that ...
I am working with the NUCLEO-C031C6 board and tried to to make the user push button toggle the user LED but it stays stuck with no change to the buttonStatus variable, always high (1).I added the counter variable to see if it is continuously incremen...
Dear All,I am testing the demo project for the NUCLEO-C071 to implement the USB HOST CDC_ACM (USBX). Below are some doubts that arose after the initial tests:After using the wizard to create the demo project 'Ux_Host-CDC_ACM', opening the .ioc file s...
Hi team What is the correct procedure to initialize FATFS for SDMMC in M4? Kindly provide the application note of the procedure. We need to run eMMC in M4 core EVK used : STM32H745I-DISCO References code: STM32CubeH7/Projects/STM32H745I...
Hi,I am trying to interface Stm32h745 controller with a 240x320 TFT LCD over FMC. Interesting thing is, when I manually control lcd control and data pins(Set them as GPIO_OUTPUT_PP), Lcd works, but when I switched to FMC it does not. Tried lots of ti...
Hi,I would like to know why when I sent the 202 bytes from pc to dev-board via USB HID, the buffer size would only get 32 byte each time, (byte[0]-byte[31])*several times until finished print out all 202 bytes?Couldn't it recieved whole 202 bytes the...
Hi everyone,I'm trying to drive a WS2812 LED strip (20 LEDs - Strip has 60 LEDs) using an STM32L432KCUx, but so far without success.I've tested multiple approaches — PWM with DMA, SPI-based encoding, and bit-banging via GPIO — but none of them produc...
