Hello,
I can't connect to a device that I've been able to in the past.
We have tried to use the J-link in different computers, with two different hardware, and it can't connect.
The difference is that we've updated the firmware.
this is the message I got on J-link Commander:
Display All
we are using custom hardware, and I've tried different speeds (50, 1000, 4000), and no success so far.
Could you help? we are tight on time!
