we are trying to program a hex file by using st link v2 programmer in cube programmer getting follow error.
no stm32 target found.
also I updated the firmware.
the target board is working with another st link.
from not working st link we are getting TCK but TMS not getting.
may be what is issue ?

Tripple check wiring, try connect under reset, try other debuggers or debug-programs for the stlink.

The failing ST-LINK is a dud?
Could be damaged at connector or cable.
Try a lower connection speed.
What type of STM32?

thank you for reply
we connected with 240kHz low speed only.
cable is working fine.
we tried with stm32h750 MCU.
here which connector we need to check ?

thank you for reply
we checked with other stlink programmers and working fine.
we tried under reset mode only and all wiring has fine.
