Hello, Currently we are using STM32G4A1VET6 MCU in our board and we dont have any high speed application in the board, suppose i dont want to use any crystal/oscillator on these pins, then how these pins should be taken care in our schematic, I check...
whether stm32 can be supplied with 5V or 3.3V only.
I am trying to start a debugger session to my new NUCLEO-N657X0-Q and getting the following error:STMicroelectronics ST-LINK GDB server. Version 7.9.0Copyright (c) 2024, STMicroelectronics. All rights reserved.Starting server with the following optio...
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...
