Questions tagged [st-link]

The ST-LINK is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families.

The SWIM and JTAG/SWD interface is used to communicate with the STM8 or STM32 microcontroller located on your own application board.

STM8 applications use the USB full speed interface to communicate with STMicroelectronics’ ST Visual Develop (STVD) or ST Visual Program (STVP) software.

STM32 applications use the USB full speed interface to communicate with ATOLLIC®, IAR™, KEIL™ or TASKING™ integrated development environments.

STM Microcontroller burns every time

I have some experience working with stm32 but I only ever used them on dev boards. I recently tried to solder stm32 and stm8 on a simple break-out board and program them with my st-linkv2 clone. On first power up, the mcu makes some little noises…

STM32 & ST-LINK - Cannot connect to MCU after successful programming

I have built my own board with STM32F7-45VGT6. I have successfully programmed it with ST-LINK v2 (not the original one though) and now I cannot even connect with MCU. I use ST-Link Utility from ST and SWD interface. It can be the case that I use SWD…

Is JTAG faster than SWD for debugging on an STM32F with STLINK-V3SET programmer?

There is a new STLINK-V3SET programmer that someone dropped off on my desk today. It supports USB 2.0. My thinking is that if SWD is the bandwidth limiter in the signal chain then a new programmer isn't very useful. Is SWD or JTAG faster with…

Do I really need to put stm32 microcontroller into bootloader mode to program it?

I have started learning stm32 microcontroller for a while using a very small development board "stm32f103c8t6" (or blue pill). when I started, I learnt from some tutorials that I have to switch a jumper in order to program it. (The photo is a…

How to make SMT32 chip programmable while it stuck in Standby mode?

From my mislead I put HAL_PWR_EnterSTANDBYMode() in the code whithout any wakeup behaviour, which made my chip unable to debug via SWD interface. So I can not either erase, upload new code or do anything with this chip. I have an Aliexpress ST-Link…

Cannot connect to STM32 after programming without activating SWD pins

We were testing the STM32 on a custom board. We were able to program it through SWD pins and an external ST link. Unfortunately, we didn't activate the SWD pins in the .ioc file. Now we cannot connect to it and we are not able to erase the board…

STM32 SWO & OpenOCD with Variable SysClock

I have been using SWO with STM32 chips for debugging for a number of years. I have managed to side-step this issue until now. I would like to be able to use SWO for debugging while varying the SysClock frequency. This is an issue because OpenOCD…
