Hi there.I got in trouble with H750XBH6.I designed a costum board base on mcu above.I followed datasheet recommendations for BGA footprint.Now I got problem with soldering. The pads are too small and doesn't make connection with chip balls.So the chi...
Hey folks,I'm trying to load firmware onto an STM32H755BI Microcontroller (Dual M4-M7 core). When loading the M7 core with new firmware, I have no issues. However, when I load the M4 core the microcontroller crashes badly. I've tried loading via Cube...
Hi, We are developing custom board for certain application using STM32F103RB for the first time. In order to program/debug we are planning to use,"STLINK-V3SET debugger/programmer for STM8 and STM32". We have gone through schematics of Nucleo - F103R...
Hello Experts,My goal is to send data between stm32h745 and stm32h750 disco board via FDCAN. However, I am not sure if this circuit works properly. Also, I don't have any CAN analyzer/tool in my hand now. So, I have doubts regarding the circuit for F...
the hole batch of F030C6T6 has same behavior :can access with ST-Link , program, verify - all ok. read core registers, option bytes...ok.but then no program start ! chip stays in startup here:10 tested boards ihave identical behavior. chips coming fr...
I am working on following platform:Hardware - STM32H745I-DISCO board.IDE - STM32CubeIDE v1.8.0.I am using JTAG mode in ST-link for debugging. I am using external QSPI flash to store my code and external SDRAM to run the code. The code first goes in b...
Hi,I designed and tried to use my custom board based on STM32F030R8T6 MCU. But the problem started from beginning.For MCU Flashing I used STM32CubeProgrammer and ST-LINK V2 (STM8 & STM32) dongle. First of all I was trying to connect the board and I'v...
I am currently developing a touchgfx GUI for a custom board which is based on the STM32F429-DISCO, therefore I use said board for the fundamental development. While initializing hardware button controll via GPIO_EXTI lines I have run into a strange i...
HiI'm new to STM32, I'm jumping from Arduino, and I'm out of my depth, perhaps I can humbly ask for some help.I've done basic projects with the Nucleo board, and I wanted to give a try with a simple code on a barebone chipI have this STM32F401CBU6 on...
Hi all,I have an STM32L4Q5VGT6P (LQFP100) on my own board. The supply voltage is +3V3 without an external oscillator. Unfortunately, the STM32 CubeProgrammer does not connect to the MCU via SWD. Error message "No STM32 Target found" (Erata of the MCU...
