Hi, while debugging STM32F072 I am facing some issues as below, At time of debug I am getting Debug warning as verify error from address onwards 0x08003800 application code size is reach just around 20KB,and controller enters in hard fault.

1. At time of debugging my application card based on stm32f072 controller I am getting Debug warning as verify error from address onwards 0x08003800 & and controller enters in hard fault. Current application code size is reach just around 20KB In case I reduced my code below 16K it doesn't give any problem. Flash size of controller is 128kb.
2. When tried to program controller using STM32- St Link Utility after connecting to target it is showing device as STM32F05x128K.
3. Same issue faced while using STM32F072B -Discovery board
