How to get STM32 to detect St link?
You can also try to remove the SWD jumpers (connector CN2) on your board to detach the ST-Link from the built-in microcontroller part. Since the ST-Link part is independent it will still be detected by the STM32 ST-Link Utility (but you will have to put the jumpers back if you want to actually program your microcontroller). Just ran into this.
Which is mini USB port does St link use?
ST Link is mainly designed to allow flashing of target MCU trough the mini-USB interface. But, it provides at least another really useful feature: a Virtual COM port. When you install the ST-Link drivers, a new device appears in your hardware devices list: the ST-Link Virtual COM port.
Which is microcontroller communicates with St link server?
The SWIM and JTAG/SWD interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board. The modular architecture of STLINK-V3SET enables to extend its main features through additional modules such as the adapter board.
What does the stlink-v3set do for the host PC?
The STLINK-V3SET provides a Virtual COM port interface allowing the host PC to communicate with the target microcontroller through one UART. It also provides bridge interfaces to several communication protocols allowing, for instance, the programming of the target through the bootloader.
Why is my STM32F4 SWD connector not working?
If you want to program the on-board target with a different programmer, you will need to study the schematics, find all the relevant signals, and make sure the on-board programmer is not loading the lines – which sounds to be about what you did in picking up the SWD pins from their GPIO breakout positions.
Why is my St-link not connecting to my MCU?
Anyway, if you need to use SWD pins as output, then add some delay at the beginning of the program or use some jumper to disable/enable setting these pins as outputs. For connect under reset to work the ST-Link must have control over the reset pin, if you tie it to ground the ST-Link has no chance to get the target running and gain access to it.
How to connect reset pin to St link?
I use ST-Link Utility from ST and SWD interface. It can be the case that I use SWD pins as output and in my code I set them as GPIO output. Can it be the case? Nevertheless, I connect my reset pin to GND and set “Connect under reset” option in ST-Link Utility but it doesn’t work… What can I do?
