Hi,

I have a connection issue with the target ATSAME54 by using JLKIN.EXE tool. The µC has already been flashed with Atmel Studio. The debugger is the J-32 Debug Probe.
Does anyone know how to solve the issue ? Is the µC stuck ?

Hi,

Thank you. Reset pin was not connected to the MCU. Now it works !
