Problem with Arduino 1.8.8 vs 1.8.5?

Ever since getting my M01 I am using the Arduino IDE 1.8.5. Just out of curiosity I checked the Arduino site for an update and saw 1.8.8 and downloaded it. But for the appSwitch function in my sketch it is giving the following errors:

$ make flash

However if I use Arduino 1.8.5, I do not get the above errors.

This sounds like a linker issue… can you check what version of gcc each arduino you use shipped with?

hardware/tools/avr/bin/avr-gcc --version (relative to your Arduino install path) should give you the version.

Arduino 1.8.5 comes with AVR GCC 4.9.2 and Arduino 1.8.8 comes with AVR GCC 5.4.0.

I can’t offer any help, but I can say that the firmware compiles just fine for me with avr-gcc 5.4.0 and Arduino 1.8.8.

You mean the default firmware? Try including the appSwitch function from my sketch linked above.
