I am using stm32-f407 discovery board with IAR. It was working quite fine but when i tried to interface a 16 x 2 lcd and downloaded the code, it gave the following error .

 Fatal error: ST-Link, No MCU device found   Session aborted!
Now it is giving same error on every code
I am new to microcontrollers and dont know much about it. if anyone has a solution please share.
