A summary and lesson for anyone after me:*If you mess up the swd connections for some reason like i did.. and you try to breakout the connections from the socket: The. Pay attention that some wires might be shorted to GND more likely in the connector...

Yes I am aware that they form a low impedance path for higher frequencies and the bigh frequency element in such train of pulses is there from the rising edges and has nothing to do with the fundamental frequency of the clock.but that wouldn't/ (at l...

Hi again, You're right pin 63 is not given in the symbol, However, it is actually connected. I checked the PCB viewer and it's present: And then i tried to delete the track to check if the RatsNest is connected, and yes it is, maybe the symbol has pi...

Hi, thank for your reply, *Regarding the 49R9 terminations I've replaced them with 0 Ohms way earlier and that unfortunately didn't help.. *For the frequency I've tried with many frequencies with no Luck*sorry what do you mean by remove "protection" ...

>>I never had such problem , if swd /swc / gnd + vdd (at 3v3) , it always connects. (software mode reset) -I just tested the voltages of such connections on the st link's swd header and got the following:VDD is 3.3VSWCLK is 0VSWDIO is 3.3V Should the...
