HARDFAULT on nRF51 DK(PCA10028) when I run lightcontrol of mesh SDK

[kren]

Hi there, I'm trying to deploy mesh v0.9.1 alpha on my board, I've already run lightcontrol server and client on my nRF 52 DK, they work well. Then I flash S130 v2.0.1 and lightcontrol server on my nRF51 DK(PCA10028), but it is always in HARDFAULT mode. I test this scenario on three nRF51 DK, the situation is the same, what's wrong with that?

How are you compiling the example, with Segger Embedded Studio or CMake/Ninja? Make sure that you are compiling the example for the correct target, i.e. ninja f_51_light_control_server.

I compiled the example like this: mkdir build51 cd build51 cmake -G Ninja -DBUILD_TOOLCHAIN=GCC .. ninja is there anything wrong?

You need to run

mkdir build51 
cd build51 
cmake -G Ninja -DBUILD_TOOLCHAIN=GCC ..
ninja 51_MBTLE_CORE

I encountered the same problem with PCA10028. I believe the HARDFAULT is caused by timeslot API, I guess Cortex-M0 core might be too slow for current implementation.

I lengthened TIMESLOT_SLOT_LENGTH_US and TIMESLOT_SLOT_EXTEND_LENGTH_US to ridiculous values (600000 and 2000000 respectively) and HARDFAULT doesn't happen anymore. On the other hand the board cannot connect to any other BLMesh node.

Hi Jakub, could you create a new question where you describe in detail how you built the example and post the debug output?
