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.

you did not answer:

> 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.

Diagram what you're doing !

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.

You don't program the IC on the ST-LINK/V3SET, it is an intermediary connection with an STM32 Target on your own board

PC -> ST-LINK -> TARGET STM32

If you want a board with the debugger, and a target chip, look at the NUCLEO or DISCO boards.

+ what is target cpu ? v3+mb1440 is just programmmer+adapter .
