NMI when using pow()

Raj

Other Parts Discussed in Thread: CC3200

Hello,

I have modified the http_client_demo in CC3200 launchpad SDK to include some calculation using pow() math library function.

When the execution reaches this point, processor receives an NMI and enters NmiSR().

Heap size is set to 0x8000, C system stack size is 0x800.

What could be the reason for this behaviour?
