cc3100 hangs at sl_SyncObjWait

Parthraj Gohil

Other Parts Discussed in Thread: CC430F5137, CC3100

Hello,

I am implementing getting_started_with_wlan_station application from cc3100 sdk. cc3100 sdk is interfaced with cc430f5137 over spi.

My issue is application goes in endless loop at OSI_RET_OK_CHECK(sl_SyncObjWait(&g_pCB->ObjPool[ObjIdx].SyncObj, SL_OS_WAIT_FOREVER)); instruction.

This instruction was successful at once and then program stopped at retVal = sl_WlanPolicySet(SL_POLICY_CONNECTION, SL_CONNECTION_POLICY(1, 0, 0, 0, 1), NULL, 0);

But now every time it goes in loop at OSI_RET_OK_CHECK(sl_SyncObjWait(&g_pCB->ObjPool[ObjIdx].SyncObj, SL_OS_WAIT_FOREVER)); instruction.

can anyone help on this?

Thanks in advance,

Parthraj

Hi Parthraj,

Host driver wait for the device init interrupt at below line

OSI_RET_OK_CHECK(sl_SyncObjWait(&g_pCB->ObjPool[ObjIdx].SyncObj, SL_OS_WAIT_FOREVER));

Can you try probing the Host IRQ pin and check if the interrupt is triggered by CC3100 device?

Please note that nHIB line should be pulled low for at least for 10 ms.
