I found a minor bug in section 07 Registers / Bad Address
When running the example with the following openocd.gdb config:
target remote :3333
set print asm-demangle on
set print pretty on
monitor tpiu config internal itm.txt uart off 8000000
monitor itm port 0 on
load
break DefaultHandler
break UserHardFault
break main
continue
gdb complains about not finding the UserHardFault function:
...
Function "UserHardFault" not defined.
...
When running continue, the program does not halt as expected in the hard fault handler, but hangs in a loop.
I looked into the cortex_m_rt crate which, does not expose the expected UserHardFault function, however it exposes HardFault.
Changing the openocd.gdb config to:
...
break HardFault
...
solved the problem and the program holds as expected on the breakpoint.
I hope you can improve this section.
Keep up the great work!
