stm32f303zet6 custom board not working

[shankarachary]

Dear sir/Madam,

I have made a custom stm32f303zet6 board for my applications. I started with a basic Led blink program. program is flashing into the MCU but the led blink is not happening. Here i am attaching the schematic for the custom board. Please help me in getting the customized PCB work.

Thanks & Regards,

So what debugging have you done so far, and what have you learned from that?

Are you sure that the LEDs are mounted the correct way around?

Are you using an internal oscillator for the MCU? According to the schematic, you only have a low speed oscillator crystal connected. Share your code and clock and IO settings.
