Breakpoints on memory write with ST-LINK/V2, STM32CubeIDE, and STM32F746?

[RBack.1]

Apparently I have a bad pointer somewhere that periodically kills some bytes in my itcm functions. It'd be really easy to find it if I could break on memory write. Does this feature exist with this tool and IDE?

Yes, you want to set up a watchpoint.

Right click in the expressions window and select Add Watchpoint (C/C++)...

Edit: 

1. Create the expression you want to monitor in the Expression tab.
2. Right click it and Add Watchpoint.
3. A breakpoint will be set up when it changes you can view/delete in the Breakpoints tab.

The debug hardware has some methods, could perhaps also try the MPU configuration and make it Read-Only, then it would just fault
