genieArduino won't work with Adafruit Feather M0

[Hasse]

Hi!
I have a problem with compiling when I use the genieArduino library.
I can't get the Arudio IDE to compile for an Adafruit Feather M0 (or other Adafruit SAMD21 boards). Other boards work (like Adafruit feather 32u4 and Adruini MKR 1000)

In my code all I have is:

-------------------------------------------------
#include <genieArduino.h>

void setup() {
}

void loop() {
}
--------------------------------------------------

So the problem is within the genieArduino library.

I am getting the error messages
error: no return statement in function returning non-void [-Werror=return-type] (multiple)
error: control reaches end of non-void function [-Werror=return-type] (one)

I run Arduino IDE 1.8.19 with genieArduino 1.5.2

I have tried to uninstall/install boards, library and the IDE.
I have tried installing boards and library on a different computer with the same results.

Is there a solution or is genieArduino not compatible with these boards?

Regards
Hans, Sweden.

Hello Hans

We are investigating and will get back to you soon

Hello Hans.

The main genieArduino branch will need some figuring out to determine what is going wrong with the Adafruit core and SAMD, however we have a DEV version which has many improvements which we have just pushed a minor tweak to enable SAMD to compile on that, and that seems to function, if you wanted to try that.

Just note you will need to use Serial1 not Serial on the Adafruit M0 board I believe, so ensure your demo code has that factored in.

Regards
