Proper flow for debugging code loaded from ROM (QSPI)

I have a board where I loaded my code into QSPI for loaded by the HPS at boot time. This works. But when I connect with the debugger, and load my symbols for that code, I cannot set/hit breakpoints, ...

Hello sir, I have found an old post regarding booting from QSPI and executing in it (XIP). no updated on yet. It might help you to define the required flow, along with the debugging script needed for debugging. The description of the flow: https://www.intel.com/content/www/us/en/programmable/documentation/hco1433528108894/hco1433527902037/hco1433528091150/hco1433528098241.html The design example: https://fpgawiki.intel.com/wiki/Cyclone_V_QSPI_XIP_Example_Design Hope this might help.

This is, essentially, what I'm doing. It simply doesn't work. The symbols are loaded but setting a break point in a piece of code I know is getting executed (as it has output to the serial port and I see that output) will never get hit: software or hardware breakpoint. I'll beat on ARM. Maybe they will help? I think this is a DS-5 issue, after all.
