sl_Task() and _SlNonOsMainLoopTask() crash (hard fault exception)

Christoph Speck

Other Parts Discussed in Thread: CC3100

My application crashs when calling sl_Task() or _SlNonOsMainLoopTask() . A hard fault exception occurs.

I am in a non OS environement and try to startup the CC3100 asynchronously with sl_Start(0,0, callback).

Is there a precondition (some kind of init) for the sl_Task() or _SlNonOsMainLoopTask()?
TI Programmer Guide swru386 mentions only sl_Task(), why?
Why do all examples in the SDK use _SlNonOsMainLoopTask() which is not documented?

Hints how to solve this problem are highly appreciated.

Regards,

Christoph

The warning in the documention of device.h:

This function must be called from a thread that is start running before any call to other simple link API

was missleading to me.

In my case sl_Task() crashed because it was called before any other call to simple link.

When calling sl_Task() after sl_Start() the call works fine.
