I wrote LED blinking code for STM32F407VET6.

When I'm using Std_Periph_driver everything is fine. But when I write just CMSIS only led blinking code, after upload hex code to STM32F407VET6 code working, st-link is disconnecting and I can't upload the code again till setting boot 0 mode to ON.

What I should add to code to fix this issue?
