   Hi All,

I am newbie with STM32CubeMX(Although on STM32F10x old libraries, along with CooCox, I have been working for last 6 years). I created a simple GPIO Toggle Project (Keil MDK-ARM) for STM32f103RET6. I configured clock with HSE(8MHz), clock source PLL(at 72 MHz).

Project created and compiled successfully. But after compilation when I loaded the bin file to microcontroller, my micro stopped every thing and even I could not connect it using ST Link V2 utility again. The same pattern has happened to me twice.

I am puzzled what wrong is happening.

Please help/suggest someone .
