Got a shiny new R4 and was going thru the tutorials. I followed the simple steps for using a break point and I start the debugger and in a couple of seconds it quits with a pop up that says
"OpenOCD: GDB Server Quit Unexpectedly. See gdb-server output for more details."
Programmer is set as in the tutorial, Loaded the board package before I started anything. Using USB C to C to win 11 PC. Program upload works perfect, and I can send things to the serial monitor, so the usb IO is working both directions. Using one of the example programs and tried some others too. Tried rebooting everything. Checked the IDE for updates. version 2.3.4
gdb-server tab:
