cc3000 got into while loop infinitely

Hi,

I got one problem about sending blocked issue.

After send/recv bytes, cc3000 is blocked in 

SpiWrite()

{

....

// Due to the fact that we are currently implementing a blocking situation
// here we will wait till end of transaction

while (eSPI_STATE_IDLE != sSpiInformation.ulSpiState)
{
;
}

}

BTW, sSpiInformation.ulSpiState = 3, in this block case.

I use SDK 1.12 and SP 1.12 on my platform.

Does anyone get the similar issue before?

 

thanks
Gavin

    Add the observation from waveform, it seems that CS and INT pulled low forever when issue occurred.

    I follow the code flow and I think this issue should be caused by missing TX finished INT.

    How to guarantee TX finished INT? Or cc3000 has crashed in this moment.

    thanks
