NUCLEO-144 H723ZG "Can not connect to the target!"

Hi there,

I received a new out of the box NUCLEO-144 H723ZG board which I can not connect, but getting the "Can not connect to the target!" message (see below)

What I've done so far:

- checked the Jumper as described in user manual UM2407 section 5 >> all as described

- started ST link utility

- plug in USB cable To CN1 (checked cable on other USB device, used different USB cables)

- Target >> Settings

   * SWD

   * default frequency of 8000 (kHz I guess)

   * Access Port 0

   * Hardware Reset   

Tryed the same setup in BOOT mode (BOOT1 pin to 3V3) as decribed here

https://community.st.com/s/question/0D50X0000BL7SnASQV/stlink-problems-with-stm32h745idisco

H723ZG goes into boot mode (no user LED blinking) but still no connection.

What am I missing?

NUCLEO-144 H723ZG:

06:23:30 : Disconnected from device.

06:23:37 : ST-LINK SN : xxxxxxxxxxxxxxxxxxxxxxxxx (valid serial number crossed out by me)

06:23:37 : V3J7M2

06:23:37 : Connected via SWD.

06:23:37 : Connection mode : Connect Under Reset.

06:23:37 : Debug in Low Power mode enabled.

06:23:37 : Can not connect to the target!

                 If you're trying to connect to an STM32W1xx device, please select Normal or HotPlug mode from Target->Settings menu.

06:23:40 : Unexpected error

cross check same setup with NUCLEO-64 F-103RB OK

NUCLEO-64 F-103RB 

06:20:24 : ST-LINK SN : xxxxxxxxxxxxxxxxxxxxxxxxx (valid serial number crossed out by me)

06:20:24 : V2J37M26

06:20:24 : Connected via SWD.

06:20:24 : SWD Frequency = 4,0 MHz.

06:20:24 : Connection mode : Connect Under Reset.

06:20:24 : Debug in Low Power mode enabled.

06:20:24 : Device ID:0x410

06:20:24 : Device flash Size : 128KBytes

06:20:24 : Device family :STM32F10xx Medium-density

Win 10

STM32 ST-LINK Utility   v4.6.0.0

ST-LinkUSBdriver.dll   v5.1.2.0

ST-LINK_CLI.exe         v3.6.0.0

Thanks for any advice

Cheers!

Use STM32CubeProgrammer instead.

ST-Link Utility is deprecated and doesn't work on newer chips.

Is this still true?  I'm using the same eval board NUCLEO-144 H723ZG and chip, okay to use STMCubeIDE but "cannot connect to target" when using ST Link Utility.

ST-LINK Utilities hasn't been updated in years and is very unlikely to be. It will work with older parts that it supported when it was deprecated.

@ETong.1 STM32CubeProgrammer. Not ST Link Utility. Use the STM32CubeProgrammer.
