I need to use OpenOCD to program/debug my FRDM-MCXN947 board. I have updated the debug chip on the board to use CMSIS-DAP and have been able to connect OpenOCD however OpenOCD always bombs out with the error embedded:startup.tcl:1524: Error: ** Unable to reset target **.
I have tried setting the OpenOCD reset_config to none and to srst_only but neither has helped. Can anyone suggest a working OpenOCD configuration for this board?
FYI, here is the full output:
openocd -f ../openocd/scripts/interface/cmsis-dap.cfg -c "transport select swd" -c "reset_config srst_only" -c "gdb_port disabled" -c "tcl_port disabled" -c "telnet_port disabled" -c "adapter speed 1000" -c "program /TEMP/test_main reset"
