How to solve it

[TDK]

Target Voltage: 0.23 V

This is insufficient voltage to power the device. Look at the user manual for how to power the device properly.

[Andrew Neil]

As @TDK said, you have no power on your target:

[peak]

Hello, how to set the voltage? I don’t understand the manual. How much voltage is needed to be adjusted to connect to ST-LINK normally

[peak]

[peak]

Hello, how do you need to restore normal operation? I don’t understand the manual very well. Is there any specific method? thank you

Hello @peak ,

Please refer to this article describes tips to fix errors encountered such as “Target not found”: How to solve connection errors when connecting and programming the STM32 target board.

I doubt it's a matter of "setting" or adjusting the voltage.

This almost certainly means that the Target is just getting no power at all.

You need to study the User Manual - there is usually a section describing its power supply options.

You could also look at the schematics ...

Hi @peak 

I'm refering to STM32N657-DK UM3300 in Figure 4. STM32N6570-DK PCB layout top view.

Could you confirm the following steps below:

1) Put the STM32N6 is in DEV_BOOT, meaning BOOT0(SW2)=L (GND) and BOOT1(SW1)=H (3.3V)
Refer to the Figure 4, BOOT0 must be set to the inner of the board, BOOT must be to the outer edge of the board.

2) Connect a data USB-C cable on CN6, check that you are not using a cheap charging USB cable. You need a data USB cable. 

3) Press RESET button (black button)

4) The LED red (LD2) must be on. That's means the N6 is in DEV_BOOT.

5) In STM32CubeProgrammer refresh the STLink version using the arrow that turns next to the Serial Number icon.

6)  Change STLink Mode as Hotplug and Access port = 1, then click Connect
Let me know if it solves your issue?

Best regards,

Romain,
