I am trying to get the CAN Loopback up and running on my STM32L431KCU (CAN1), I have tried to follow the: Guide to CAN (bxCAN/CAN2.0) configuration in Loop back mode on STM32 MCUs. But I am getting stuck in the "HAL_CAN_Start()" function where its wa...
Hello, I’m starting a new design with the STM32H755. I also have the dev board (Nucleo-H755ZI-Q), but I do not have its schematic.So far, the closest schematic/design reference I’ve found is Figure 18 in AN4938 (“Getting started with STM32H755”). Cou...
Hi all,In my project I use several IOs, I2C, SPI, UART, ADC, DAC and most of them work as expected.However, I have 2 inputs from push buttons (pushing the button would set them to 0 volt), set with pull-ups (not set as EXTI) that sometimes stop worki...
Hi everyone,I am bringing up a custom board based on the STM32H743VIT6. I am trying to connect via ST-Link (SWD), but I am getting the standard "Can not connect to target" error in STM32CubeProgrammer.The Setup:MCU: STM32H743VIT6Debugger: ST-LinkInte...
My STM32H533VE works as PD Sink.We connected CC1/CC2 with DBCC1/DBCC2 (as AN5225), STM32 cannot power up with a USB PD adapter. The adapter supplies power for ~20ms then stops the supplying.If I remove the long time initialization code (LSE initializ...
Hello there,I'm trying to create a project for stm32h7s7 with external loader. But when i added the external loader in IOC file the all indexes were lost in editor mode. But I checked for building, i can't see any problem. I tried index -> rebuild bu...
Hello,I am using NUCLEO-H755ZI-Q (STM32H755) and I am observing a reproducible boot issue related to high system clock frequency.1. Hardware / EnvironmentBoard: NUCLEO-H755ZI-QMCU: STM32H755Power supply: USB (on-board)Debugger: ST-LINK (Connect under...
The Errata sheet for STM32G030x6/x8, ES0486 - Rev 6, states in chapter 2.2.9:After connecting the debug interface and until the device power-down, the boot source upon reset or wakeup from a low-power mode is determined by the PA14-BOOT0 pin level be...
Hi,The external nor flash AT25XE321D is 32Mbits, support quad IO/XIP spi operation, max. 133MHz Freq. Std. JEDEC/SFDP. It is connected to STM32H7R7Z8J6 with with XSPI1 port-1 interface.I am using MX v6.116.1 to setup project for my board. By IDE v2.0...
Hi everyone, I am facing an issue with CAN communication on STM32F446ZCT6, where the CAN controller frequently enters the Bus-Off state. Hardware Details MCU: STM32F446ZCT6 CAN Transceiver: (TJA1042T) I am working with CAN communication on STM32F4...
