Hello ST Community,I have a PCB designed according to the attached schematic.Recently, I have been struggling with the following awkward issues:1) The flashed firmware (via UART) doest not always start (2/10 attempts lead to successful code execution...
Hello!It's been a while since I'm working with STM32H7 MCUs and now, some of the products using it are returning from my customers, not working at all. Analyzing the board, I get a short circuit between 3V3 and GND and after removing the MCU, the sho...
It says we can measure power consumption of mcu by putting a ammeter at JP6 in page 23(https://www.st.com/resource/en/user_manual/um1724-stm32-nucleo64-boards-mb1136-stmicroelectronics.pdf).I write a program just detecting button, if button pressed ...
I have multiple ST-link's but no option to select the ST-link in STMStudio. Could you help me find it. Or is there any standalone debugger for STM? I really don't link ozone. Because it is consuming too much memory.
i am not able to run any code on bank2 with STM32L151RE with 512kB FLASH.program was loaded on both regions 0x0800 0000 and 0x8004 0000if nBFB2 is checked the code runs ok, if i just unched the code does not run....what am i doing wrong?
Hi All,Does anyone have the circuit diagram (schematic) for this board?Basically (and I have posted about this before, without any conclusion) I have several boards which work perfectly (sw download and SWD debug) via the big 20-way CN2, but are unre...
my goal is to use this board in [-40°C +85°C] climatic chamber.Regards:)Oliver
I'm using an ST-Link/V2-ISOL and installed the drivers (stsw-link009_v2.0.2) and ST-Link utility but I keep getting the "Target, detection failed" error in the Utility. Same result in the STM32 Cube Programmer. How can I fix this issue? I am using 64...
We were using STM32H730VB to drive a LED display in our project. Pins 51 - 64 drive the LED display, Pin 30 controls the display power, and pins 24 - 25 act as the USART. We use CubeProgrammer to download the firmware.This worked well and with no is...
