How to apply cc3100 on the platform with OS?

Hi Geet

I refer the sample code to init cc3100 in task routine, but it seems that can't get the feedback from the init callback function and it's always blocked in the while loop, so cc3100 can't be initialized. I use the such code on the platform.

void InitCallback(UINT32 Status)
{
      g_ulDeviceNetworkMode = Status;
      g_usStatusInfo |= MCU_SLHost_INIT;
}

void WlanTestTask( void *pvParameters )
{
       bool bTestOn;

       /* Initializing the CC3100 device */
       sl_Start(0, 0, InitCallback);

       while(!(g_usStatusInfo & MCU_SLHost_INIT))
       {
              //looping till simplelink starts
        }

        /*set NWP as station mode */
        sl_WlanSetMode(ROLE_STA);

        for ( ;; )
        {
                if( xQueueReceive( g_xWlanTestQueue, &( bTestOn ), portMAX_DELAY ) ){}
        }
}

Do you have any idea about it.

thanks

Hi Geet

In the previous post, I said that system was blocked in init callback function. So I try to remove it and I got another result, the system will be blocked in FaultISR loop after calling

"OSI_RET_OK_CHECK(sl_SyncObjWait(&g_pCB->ObjPool[pObjIdx].SyncObj, SL_OS_WAIT_FOREVER));" in device.c

Do you have any suggestion?

thanks

Hi Gavin,

It seems that you are not getting the init complete message, maybe you host MCU isn't handling IRQ correctly.
Can you please describe your environment a bit more? which MCU are you using?
Can you please try running the "spi_debug_tool"  example? and update if it succeeds or not? it will verify that the SPI & IRQ lines are connected properly.

Thanks,
Alon

HI Alon

My platform is TM4C123G EVM + cc3100 BP2.0, SDK0.5.

This platform can work on non-os environment, so SPI/IRQ should be connected properly.

I use the same SPI and simplelink source on OS environment.

I check one different in the init process between non-os and os.

In os part, it seems that there is something wrong in the sync obj list, I attach the screenshot of CCS.

Do you know what is the cause of this?

thanks

Hi,

I get the bootloader version: 2.0.2.3 and chip version:3 from uniflash.

I 'd like to confirm this version can support the OS porting.

Is there anyone can help to confirm?

thanks

Hi,

As my experience, I stuck in the same line, too.
But it come out with other problem, the semaphore object is absolutely fine.

sl_start will call spi_open, spi_read, spi_write to make sure all spi (if you use spi to communicate with c3100) driver do work.

If anything hardware setting mistake in those three function, you will have FaultISR in the end.
