I am currently using multiple STM32U5 series and STM32L4 series MCUs in a single system.I would like to share a single physical programming port (e.g., SWD or UART) among these MCUs and switch between them to program each one individually.I have alre...
For some reason I am unable to connect to my custom STF32F405RGT6 board via SWD or JTAG.I originally had my board wired as this table below:ST-LINK/V2ST-LINK/V2My BoardMy BoardPin NumberConnector CN3MCU PinMCU Pin1Target VCC 2Target VCC VCC3TRST 4G...
Hello, I just bought a Stlink-v3mods. I was wondering what's the pinout of the cn3 connector. I couldn't find anywhere on the documentation. Thanks.
Hi I don’t know the reason, but my board’s ld2 and ld8 leds are blinking, and the program says No STLink detection, even if I connect it to the usb port, what can be its reason? How can I fix it?
Hi, I tried to connect my board to my computer trought USB but I can't recognize the board, it doesn't appear, I can't use the Programmer either. I downloaded different drivers, I used different cables but it doesn't work. What can I do? The BLE conn...
My board is the NUCLEO-H743ZI2, I've looked in the manual but haven't found anything so far. Maybe I could remove jumper JP2 so the Nucleo's MCU stays powered down and then connect the CN2 connector (SWD) to the external MCU?Thanks!
你好 我正在与 STM32H755BIT3 一起做项目。我设计的电路板的现状是，用DC-DC 3.3V电源上电后，芯片很快发热严重，不出现短路就无法下载程序。我推测这是由于外围电路的设计。 有人可以帮忙找出问题所在吗？ 提前感谢大家的任何提示。 Translation: Hello I am working on a project with the STM32H755BIT3.The current situation of the board I designed is that after...
Hello,In my project using the STM32H755 Nucleo development board, I need to use PA11, PC14, and PC15 pins as GPIO Output to drive relays. However, when I checked with a digital multimeter, I found that these pins cannot be driven to logic HIGH — they...
Hello, I've been trying everything for days to fix this error. They said to set the BOOT0 pin to GND. I followed these steps. I tried many solutions from YouTube videos and the STM32 website, as well as solutions from forums, but none of them worked....
Hi everyone,I am working on a project with the STM32H755ZI-Q (Nucleo H755ZI-Q) board, and I am following this tutorial for Inter-Processor Communication (IPC) using OpenAMP: Link to tutorial.The setup involves two processors (M4 and M7). Here's the ...
