| This is due to a few factors, some of which are: | ||
|
|
||
| - Limited availability of resources for debugging. For example, some bugs such as memory corruption are very difficult to diagnose using software breakpoints. In those scenarios, you would rely on hardware breakpoints and usually there is a limited number of hardware breakpoints for a specific architecture. This makes debugging complex bugs a challenging task. |

wouldn't you use watchpoints rather than breakpoints for memory corruption?

Yes. I'll update to reflect this.

This is an odd choice to me. Why not update the path in .bash_profile instead?
$ vi ~/.bash_profile
...
export PATH = <Your Folder>/nRF-Command-Line-Tools_9_8_1_OSX/nrfjprog:$PATH
export PATH = <Your Folder>/gcc-arm-none-eabi-7-2017-q4-major/bin:$PATH

I wouldn't completely disable optimizations, instead it's easiest to use -Og or even just -O1 when you're debugging.
Worth adding a line to say all optimization levels will work, but some variables will disappear in higher optimization levels as they get optimized out.

Got it. I'll make that change.
| To start the J-Link GDB Server, run the following command: | ||

| ```terminal | ||
| $ JLinkGDBServerCL -device nrf52840_xxaa -if swd -port 2331 |

would be nice to explain that -if swd selects a SWD interface rather than JTAG. Modern chips all use SWD but older chips may require JTAG.

This is great! Go ahead and merge it. I'll fix up the image links once its in master. |
I don't think I have necessary permissions to merge it. Or am I missing something? |

Woops, you're right. Done! |
