CC3100BOOST: CC3100BOOST

Part Number:CC3100BOOST

Hi,

I interfaced the CC3100boost and CC3100MODboost to the MSP-EXP432P401R Launchpad. And I am using SPI. SMCLK is 6MHz. Whenever I do a start using ths sl_Start, I don't seem to run into any problem. But When I try to do a sl_stop or if I wana obtain the chip information, the code hangs at the IRQ subroutine. it looks like from there, when it goes to pIRQeventhandler(0), the code jumps to  hardfault error. Any thoughts as to why this is happening?

Thanks.
