Hello,
We are facing some unreliability using a JLink-Plus and JFlash with some of our custom boards.
I am suspecting noise/interference on the connection/cabling from the board to the JLink.
I know that "ShowHWStatus" will tell me the voltage measured on the supply pin (for me, that should be around 3.3V). I know it can also show target power consumption, but since these boards are powered externally, I don't expect to use that feature (and I'm not sure it's available on JLink-Plus anyway).
But what do these mean:
TCK=1 TDI=1 TDO=1 TMS=1 TRES=1 TRST=1
I know these are JTAG pins, but we are using SWD. How does the JLink "simulate" them? Do they mean anything at all when using SWD?
As I said, I don't think there's anything wrong with our JLink -- I'm just trying to help isolate where the issue might be in our cabling or connection.
