Single Stepping with STM32F7
I don’t use gdb in it’s ‘raw’ mode like that. And since this is a forum for the System Workbench, which has a built-in debugger, I could doubt anyone here does. (yeah, the bult-in dugger uses gdb but but that’s kinda hidden from normal use).
In the System Workbench (aka AC6) and in other debuggers I have seen the lines ‘bounce’ around. This is due to optimization, the assembly line the code is actually on does not match-up to an actual ‘C’ line, and/or the optimizer has merged several lines, and/or some of the code is in-lines and some is in a library that has no debugging symbols, etc, etc, etc.
Check the makefiles, or the build setup and make sure debugging is turned on and optimizations are turned off.
