- I kicked-out the SWD to use the LPC-Link connector for other Debuggers too.
Is it ok to connect EXT_POW with VIN (3,3V Regulator Input)
LPC-Link is SWD :eek:
Your connector is still incompatible, what's R27 there :confused:
EXT_POW is supplying LPC-Link 3.3V regulator to supply your target board, if LPC-Link is not powered by USB. That's not working with 3.3V.
Anyway, do you need to supply your self powered board via LPC-Link ?

- ISP P2.10 is now pulled up with a jumper to 3V3 over 22k Resitor.
Use the resistor to pull this pin up and the jumper to ground it (to switch to ISP, if necessary) :)

Sorry I didn't get you. You're talking about R12 right (1k resistor)?
No I'm talking about your funny R12/R2 construction, which you are trying to sell as a 1k pullup :confused:

I now connected a12K Resistor near the LPC-Link NRESET Pin, this should be ok now right? Did you mean this?
That's nonsense.
