[OpenOCD-user] Anyone using OpenOCD with an NXP FRDM-MCXN947?

[Rob M. <Rob...@u-...>]

I am trying to use OpenOCD (v0.12.2) to program/debug an NXP MCNX947 chip (ARM CM33) on a FRDM board.  I can get OpenOCD to connect but it always bombs out with "Unable to reset target".  I've tried setting reset_config to none and to srst_only but neither has made a difference.  Can anyone suggest any other ways forward?

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"
