So i have been stuck on this problem for a while and I desperately need some help understanding what could be wrong. I am using STM32CubeIDE v1.8.0 and a NUCLEO STM32F446RE board to test some basic code that blinks an LED. This works absolutely fine....

Brining this up again in case anyone else would be able to help. Does anyone have any other thoughts as to what would cause issues at higher clock speeds? I have tried my best to replicate the Nucleo's datasheet on my breadboard and custom PCB's, but...

I'm using a separate ST-Link, see attached. I actually have tried to use the onboard ST Link from the nucleo, but that has made no difference.

I unfortunately don't have a scope to verify. Is there a reason why the Nucleo wouldn't suffer from this but the custom board would? Maybe something inside the ST Link v2 that limits the current? I even tried using the 3.3v and GND pins from the Nucl...

I assume current wouldn't be a problem, since ultimately all the current is coming from a USB port on my laptop, just like with the Nucleo board which has no problems at all. I did continuity tests from the pins of the STM32 to my header pins which w...

The breakout board was produced by JLCPCB. I went through each of the pins and did continuity tests to see if adjacent pins were shorted, but each were fine. So the hard fault changes depending on if i increase or decrease the clock. At 50 MHz and lo...
