Hello,
I’m trying to run and debug code on an adafruit_itsybitsy_nrf52840.
I have this connected to the host OSX (catalina) machine only via usb - no jlink
hardware is connected. I’m trying to realize the promise in docs that no
external debugging ice or etc is required.
Is a jlink box requred for this board?
I can upload and run a sample program but debugging fails thus:
Connecting to J-Link…
Connecting to J-Link failed. Connected correctly?
GDBServer will be closed…
Shutting down…
undefinedCould not connect to J-Link.
Please check power, connection and settings.
PlatformIO Unified Debugger → Redirecting...
PlatformIO: debug_tool = jlink
PlatformIO: Initializing remote target…
.pioinit:16: Error in sourced command file:
:2331: Connection refused.
Thanks for any pointers or help.
Regards,
j
