For the last weeks, I have been trying to get this new version to work. I did the same as with the previous version and now it is running on the Xilinx Nexys4. However, honestly I do not have any idea how to get the debugging to work. I defined the pins for SWD and connected to an Segger J-Link, but no connection was possible. There is the configuration option ‘define ARM_CMSDK_INCLUDE_JTAG. In removed this, no success. I changed to ‘define ARM_CMSDK_INCLUDE_SWD, no success. I am running out of ideas.
It seems I am missing something important.
Kind Regards

A few things to check:
1) Check reset type to System Reset Request to see if it helps
2) I think the SWJ option can be uncheck as the Cortex-M0 DAP don't have protocol switching
3) Connection of SYSRESETREQ (System Reset Request) - can it generate a system reset?
4) JTAG/SWD clock constraints in synthesis, is it missing?
Hope it helps.
