hallo, I'm programming the STM32F072CBT6. In the programming "STM demostrator gui" screen I check the "after programming Jump to the user program" but after programming the STM32F072CBT6 remain locked.

With some other microcontroller it works propetrly.

Why with STM32F072CBT6 doesen't works?

Perhaps due to the mapping of the zero space memory, and the way CM0 manages, or lacks control over, the Vector Table mapping.

Suggest you try adding code in the Reset Handler to enable the SYSCFG peripheral and remap the FLASH into the expected location.
