arduino_due not generating proper config with cmake (crash)

[ntakouris]

I am trying to build the sample 'hello_world' app, after having properly installed everything according to the guide (msys on windows + gccarmemb) and I get the following error:

`
$(inside /build) cmake -DBOARD=arduino_due ..
-- Selected BOARD arduino_due

I could try to set SYS_CLOCK_HW_CYCLES_PER_SEC to 84MHz <=> 84000000 Hz to remove the warning but I guess that is wrong and doesn't need to be set.

For the CONFIG_CPU_CORTEX_x, I don't know what to do. I tried setting it to M3 or SAM3X8E but the config file would rewrite upon the cmake command.

No makefile or ninja files are generated of course...

Was not able to reproduce with this environment:

OS: Ubuntu
Toolchain: Zephyr SDK
sample: samples/hello_world
BOARD: arduino_due
git revision: b05ba6b

I have seen this before with a non-clean build directory. Can you confirm that you can reproduce this with a clean build?

Was not able to reproduce with gccarmemb either.
