Hi, I am not sure why I am not able to program my STM32F103C8T6 on the board I just designed as part of my internship. I have tried unlocking the flash, putting pull-ups/pull-downs on various JTAG lines, ensured all my VDD/VCC on the chip are hooked up and properly decoupled, and a variety of other ideas. Here is what I get when I open the JLINK command line utility:

Any help would be highly appreciated.
Thank You,
