This works for me and it makes the UI feel a little snappier (could be placebo, not sure if the UI is firmware or screen hardware limited). If I have a large number of local changes or custom images I find the firmware won't fit in memory with O3. I've made it O2 for now to save any future headaches from new features.

That's interesting. The optimisation level is currently set here. I wonder if this is taking precedence over it |
|
Good catch. Can't believe I didn't check that makefile. The -O2 I added gets appended after -Os in libopencm3.rules.mk From the GCC manpage:
I will move my changes when I get home. |

If you move them then dpsboot will be compiled with it as well. It might make more sense where it currently is |
|
As soon as you move your changes @JackNewman12 I will merge this. |

We'll want to keep the bootloader as -Os I think. Give us the most FLASH we can for the application. The application as -O3 makes sense though if we can afford it |
