CC3100 Host Porting, stuck in sl_Start(0, 0, 0)

Other Parts Discussed in Thread: CC2650, CC3100, CC3100BOOST

Hi All,

Now, I am porting host driver interface with TI CC3100 on CC2650 through SPI interface. I have trouble when call sl_Start(0, 0, 0) to initialize device CC3100 (I have CC3100BOOST module), it is stuck in "_SlDrvSyncObjWaitForever(&g_pCB->ObjPool[ObjIdx].SyncObj)". I referred many topic in Forums, they indicate that pin IRQ not assert, seem my Host MCU can not receive IRQ signal from CC3100. But, I dont know that this problem cause by CC3100 or esle. I'm not sure. I have connected IRQ, nHIB, SPI pins of CC3100BOOST with CC2650 SmartRF06 EB.

Please tell me why?

HI Anh,

Getting past sl_Start is the primary hurdle in porting to a new MCU, so what your experiencing is quite common. I encourage you to check your IRQ line physically to make sure it asserting, and that the appropriate interrupt is being triggered in code as a first step.

Hi Mr. Aaron,

I checked IRQ pin on CC3100BOOST module and, I don't assert. I dont know why. What's happen with CC3100?

Hi Anh,

If the IRQ is not asserting, then most likely nHIB is not being asserted. Can you verify this?

Thanks,
Aaron

Hi Mr. Aaron,
Thank you so much! My mistake is short wrong pin in J8 header in CC3100BOOST to MCU instead of shorting to LDO when using with CC2650 SmartRF06 EB

is this independent of all other settings, that is to say, assuming nReset is High, CS is high, Host_intr is low (during initialization), and the power is present, that simply driving nHIB from low to high will cause HOST_INTR to be asserted by the cc3100?
