CC3100 hangs - driver.c line#1236

Other Parts Discussed in Thread: UNIFLASH, CC3100, CC3100BOOST

I was able to successfully port the driver into my RTOs. I was able to setup the module into an AP with a DHCP server. However, after trying to attempt to re-initialize the device again, the device will hang right at this line:

while ( ! N2H_SYNC_PATTERN_MATCH(pBuf, g_pCB->TxSeqNum) ) (driver.c #1236)

 

I even tried to get it to run with the EMUBOOST board and the sample VS project but it will do the same thing. I tried to reformat it with the uniflash application and re-load the service pack hoping that it will set it back to mnfg default. The device is stuck with the previous settings and it will not allow me to change settings or control it at all.

    Hi Cespinoz,

    Formatting and re-flashing the device should restore the default configuration.

    Few questions:

    • Did you select the secure option while formatting the device? (secure option should be checked for CC3100)
    • which SDK version you are using?

    Regards,

    Ankur

    Hi Ankur1,

    Yes I did.

    When you said re-flashing, are you talking about the service pack .bin file or are you referring to a different firmware file?

    SDK version: v1.0.0

    Service Pack version: v1.0.0.1

    Were you able to check the SPI logs? Do you see anything in there that can provide me with any information

    Hi,

    Yes, With re-flashing I am referring to the service pack file.

    • Can you try 'getting_started_with_wlan_station' application from the SDK?
    • Can you please share the logic file for failed case and the corresponding code snippet?

    Regards,

    Ankur

    Ankur,

    I tried the VS (getting_started_with_wlan_station'project) project; it hangs also. Please remember that this board was functional with the sample projects and my environment. It worked in my environment a couple of times then it stopped working. 

    It happens right in this function (VS project) - EMUBOOST setup)

    1. configureSimpleLinkToDefaultState()

        a. sl_Start(0, pConfig, 0); (it never starts)

    The code is straight from the core API driver .

    while ( ! N2H_SYNC_PATTERN_MATCH(pBuf, g_pCB->TxSeqNum) )

    {

    /* 3. Debug limit of scan */

    VERIFY_PROTOCOL(SyncCnt < SL_SYNC_SCAN_THRESHOLD);

    /* 4. Read next 4 bytes to Low 4 bytes of buffer */

    if(0 == (SyncCnt % (_u32)SYNC_PATTERN_LEN))

    {

    NWP_IF_READ_CHECK(g_pCB->FD, &pBuf[4], 4);

    _SL_DBG_SYNC_LOG(SyncCnt,pBuf);

    }

    /* 5. Shift Buffer Up for checking if the sync is shifted */

    _SlDrvShiftDWord(pBuf);

    SyncCnt++;

    }

    Please let me know if you need more info.

    Just to confirm your application hangs inside function 'sl_Start()' at line highlighted in yellow, both while using the EMUBOOST and MCU.

    while ( ! N2H_SYNC_PATTERN_MATCH(pBuf, g_pCB->TxSeqNum) )

    {

     /* 3. Debug limit of scan */

    VERIFY_PROTOCOL(SyncCnt < SL_SYNC_SCAN_THRESHOLD);

     /* 4. Read next 4 bytes to Low 4 bytes of buffer */

     if(0 == (SyncCnt % (_u32)SYNC_PATTERN_LEN))

    {

    NWP_IF_READ_CHECK(g_pCB->FD, &pBuf[4], 4);

    _SL_DBG_SYNC_LOG(SyncCnt,pBuf);

    }

    What are the jumper settings on your CC3100 BP and EMUBOOST board?

    Can you please share the logic file capturing the following CC3100 BP pins of header to help analysing the issue further?

    1. Host IRQ pin (P2.2)
    2. SPI Lines
      1. CS (P2.3)
      2. CLK (P1.7)
      3. DIN (P1.6)
      4. DOUT (P1.7)

    Regards,

    Ankur

    Please capture the nHIB pin (P1.5) also.

    Regards,

    Ankur

    4657.500ms_Div.zip

    After looking into it further - it never breaks out from the while loop. Yes with both EMU and MCU.

    Using jumpers recommended from the documentation (SDK | gettingStartedGuide | fig1 and fig 2).

    O-scope captures: SPI lines with Irq and Clk are attached. These captures were done using the EMU board not my setup.

    Fyi - I ordered new CC3100EMUBOOST and CC3100BOOST boards. I'll capture the SPI traffic with the boards and will post it here so we can use it as a baseline.

    Yes , I have the same problem ,how to solve it?

    Looped:

    VERIFY_PROTOCOL(SyncCnt < SL_SYNC_SCAN_THRESHOLD);

    Hello,

    I would also like to request help with this same issue. My application and sample application DID work reliably and now it no longer works. The debugger shows it stuck on this line:

    VERIFY_PROTOCOL(SyncCnt < SL_SYNC_SCAN_THRESHOLD);

    At this point in time SyncCnt = 2000, which is SL_SYNC_SCAN_THRESHOLD.
