As you can see by the schematic, BOOT0 gets pulled to 3.3V or ground. I pulled it to 3.3V with the switch then held the reset button for several seconds. I currently have a blink program flashed that blinks an LED. When I try to reset the board in bo...

I used two regulators thinking that this way I could be sure I'd have enough current capacity since I wasn't sure how much the MCU would draw, in the next iteration I'll only use one. As for the capacitors, I used multiple decoupling capacitors becau...

UPDATE. To test if the routing/placement was the issue I wired a pin directly to PA14 (SWCLK) and tried to run ST-LINK at full speed, this worked. So I believe the signal switching layers and crossing traces was likely the issue I was having.Here's a...

The wiring for the programmer is fine. I believe the issue is the way I designed the PCB. To wire the SWCLK to PA14, I had to remove the boot switch from the board and solder a pin to the pad directly. The issue I think comes with the trace that the ...

Thank you so much for the reply. I actually tried doing just that before. I found out that the issue was that I was using too high of a SW clock frequency. My board can only tolerate a maximum frequency of 15kHz. Once I lowered the frequency to 15kHz...
