Hi @Anil​ , are you using Win10? If not, you might try to reinstall the STM32 Windows drivers.

Otherwise try to flash the native code you can find in the Unico package in DFU mode (with STM23CubeProg)

Thank's for your reply...if you don't mind could you please elaborate those things said by you.. As i tried few things like keeping the STEVAL-MKI109V3 board in DFU mode and after that opened the cube programmer and tried,but there also it is not detecting as COM port and i have tried to get the native code but i can't able to find where the code is present.
