I just spent some time debugging a fundamental compatibility issue between an MPU and its RAM, and I wanted to share what I learned to save others the same headache.I was looking at using the STM32MP657 (a powerful Cortex-A7 MPU) and almost made a cr...
Hi everyone.I'm trying to send more than 256 bytes of data from the host to the STM32 using USB CDC VCP, and I don't know why VCP won't accept more than 64 bytes of data. My project is already halfway done. If I switch to the USB bulk method, do I ha...
I’m working on a project that requires bidirectional communication between daisy-chained STM32F103C bluepill boards and an ESP8266. I’m using a master-slave architecture and UART for initial testing and prototyping. The chain has 3–6 STM32 boards. Ri...
Hi, I have a question about supplying power to DSI interface on STM32H747BGT6 (208 LGFP package).RM0399 says, "The DSI interface is supplied from a dedicated VDD12DSI supply that can be provided eitherby the integrated DSI regulator or by an external...
Hello everyone,I'm working on a custom board with an STM32H563 and using CubeMX, HAL, and ThreadX.I am trying to receive variable-length UART data via DMA using HAL_UARTEx_ReceiveToIdle_DMA(). My problem is that the HAL_UARTEx_RxEventCallback never t...
Hello, I have designed a custom PCB using STM32N657I0HxQ and W25Q32JWZPIQ NOR flash. I am following the STM32N6 FSBL Load & Run tutorial https://community.st.com/t5/stm32-mcus/how-to-create-an-stm32n6-fsbl-load-and-run/ta-p/768206 , but have troub...
Hi, Im planning on using STM32H747BGT6 in LDO mode only and no USB interfaces will be used. What should I do with SMPS pins (VSSSMPS, VLXSMPS, VDDSMPS, VFBSMPS) and USB supply pins (VDD50_USB and VDD33_USB)? The datasheet nor the application note don...
Hi All,I'm new to using the STM32 and honestly had great grief trying to connect to the chip.I'm using STlink V3 and designed my own PCB.Trying to flash a F/W to the PCB. I ordered the PCB from JLCPCB.I keep getting unable to get core ID as a message...
The datasheet for STM32U585 and 575 list there are two SAI on the chip. In CubeMX I can only see SAI1 (A and B sub-blocks)Datasheet CubeMX pin menu
I tried to follow this tutorial: How to build an AI application from scratch on the... - STMicroelectronics Community , could not figure out how to enable NPU RIF, so i skipped it. I tried to debug using the FSBL main.c, the blue led did turn on, but...
