I'm using stm32 cubemx with keil 5 to program simple blink on stm32f103c8 bluepill board with stlink/v2 i have configured pins RCC SYS and GPIOC 13 as output with 8 Mhz input frequency and HCLK is 72 MHz when I download code code from keil nothing happens led does not blink and it shows 1.8v at PC13 pin, please help me to figure out what I'm doing wrong.
