Hello,I have a problem with a clock configuration on my STM32F072C8T6. I need the 48MHz clock (HSI48) for the onboard USB communication. I have enabled this via ioc in the clock configuration. Everything looks fine there and no conflict is reported.N...

Thanks for the reply and the help, I didn't know that about BOOT0...I left that open on all previous designs.The oversight with the VSS/VDD pins is however quite embarrassing to me. I'm also surprised that the part works without it at all. Will corre...

Yes I measured that this morning, it was about 16mA, so 150mA is actually more than enough.This is always the point that you do not want to admit. It could very well be a bug in the design, because I did my software development with the Nucleo-F072R...

That's true, of course, but I also thought it was an incorrect measurement on my part.I could now test it in the lab and got the same result again (with my pricey lab power supply) . As soon as the CR2 register is written (any bits), the microcontrol...

Now a little update on my problem.I have now put the USB and HSI48 problem aside and after a while I noticed that probably the power supply really causes the problem. If I use too many GPIO's (at high speed), the MCU also says goodbye (at 8MHz clock)...
