I have a stlink v3set. mcu are stm32f723iek6. To me it is not possible to select mcu target. Can you give to me an idea how to select apropriate target?

Hello @vVukm.1​ 

Could you further explain the issue please?

Are yo using STM32CubeMX or STM32CubeProgrammer ?

[vVukm.1]

I'm using STM32CubeIDE and STM32CubeMX and CUBE STM32CubeProgrammer

and in any of this programs I 'cant select target STM32F723IEK6.

Reposting the same information doesn't advance the conversation.

Perhaps show STM32 Cube Programmer connecting with the ST-LINK/V3SET, and the STM32F723 MCU on *YOUR* board.

Are you talking about the STM32F723IEK6 that provides the ST-LINK functionality? Don't expect to be programming that.

Hello,
I am only trying to write a simple program using STM32CubeIDE
connected with STLINK-V3SET.
When try to debug answer is:
Error in initializing ST-LINK device.
Reason: No device found on target.
Error message from debugger back end:
localhost:61234: Connection timed out.
Failed to execute MI command:
target remote localhost:61234

What is the ST-LINK/V3SET connected too?

The ST-LINK should be connecting to some STM32 device on a board you attach it too.

Hello @vVukm.1​,

It looks like your ST-LINK device is not being detected. There are a few things you can try to fix this issue:

1. Make sure your board is properly connected to your computer and the ST-LINK device is securely attached to your board.
2. Try different USB ports on your computer.
3. Disconnect your board from power and USB, and reconnect them again.
4. Connect under reset using STM32CubeProgrammer
5. Did you try using a ST Link V2? as it is more stable.
6. Check the ST-LINK configuration area and make sure the serial number is properly refreshed.

Also what board are you using exactly?

[vVukm.1]

Hello,
All of your suggestions are already done. But there are no
changes.
I have not used STLINK-V2.
Are there any possibility to activate my STM32F723IEK6?

what you want - if not show, what your doing ?

Hello,
STLINK_V3SET is only connected to my Laptop.
I am trying to prepare some program to switch on/of LED
connected to GPIO on CN9 of MB1440.
