ST link V2 wont connect to STM32L562CET6

[ABhas.1]

Hi All,

I have a ST link V2 and STM32L562CET6 boards. I tried all possible solution available online but still cant connect to MCU. STlink has the latest firmware.

1. My board is good because i can program it using segger programmer
2. wiring between stlink and kit is good because stlink can detect the MCU

i am using these connections

1.VDD-3.3V

2.SWDIO

3.SWCLK

4.GND

5.NRST

tried on 3 new units and none of them will connect.

 

Boot 0 is pulled low.

any help will be appreciated.

Thanks

Never had problems with L5.

Does it really have firmware ? If yes,it can be in low power or badly configured. Reboot with boot pin high. It should connect them

Also reset if connection is correct to pa13-14 pins​

thanks for quick response

i tired with boot0 high but didnt help.

i tired the units which are never programmed and they are showing same behavior.

By default the reset pin is pulled high. i tried with pulling it low and connecting and erasing but didnt help either.

Does ST-LINK Utilities support the L5 parts? The software's deprecated, try using the STM32 Cube Programmer software
