help with reset breakpoint and watchdog implications #1695
-

hi all. i'm using bmps for an embedded course where students essentially build their own rtos from bare metal on a board with an nRF52840. we're using largely stock firmware, with the exception of enabling RTT and trimming out some code to make the image small enough to flash. i noticed that when we program in a system reset ("soft reset"), the bmp catches it and triggers a breakpoint. this didn't happen with our previous debugger, and i'd like to eliminate it if possible. does anyone know how i could quickly modify the blackmagic firmware to not trigger this breakpoint on reset? it's particularly problematic if students build a watchdog. |
