Impossible to compile with GCC 4.9 #12
Comments
Use my version https://github.com/rogerclarkmelbourne/STM32duino-bootloader |
@rogerclarkmelbourne, does that advice still hold? On the linked repo, it says "Also Note. Use GCC 4.8 (not 4.9 or newer, as these versions have more aggressive optimisation which causes hardware registers not be read correctly and consequently the bootloader does not work)", so I suspect that this problem is not fixed by your version? |

I've been trying for several hours to get the maple bootloader to compile with GCC 4.9 which, for some reason, seems to be impossible. Even with "-O0" the resulting binary doesn't work. I did several tries to find the problem but failed so far.
