Both returns -> :? ...... with zephyr-SDK

I also tried to compile the App using latest gcc-arm-none-eabi-7-2018-q2

Yes.

CONFIG_MAIN_STACK_SIZE=512 ....to 1024
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048 ....to 4096


But still getting MPU Fault in case of Board executing BT Mesh Servers.

Hi,

 

FYI,

With v1.12.99 I'm mot facing any MPU FAULT issue (while testing for #onoff_level_lighting_vnd_app)

It has last commit -> ba6763a187a347cfc825a2bece78e7d1ef28772d

 

That means something after it has changed the things bcz of that we are getting

MPU FAULT.

 

Thank You !!
