CC3100: sl_Start() problem after the latest service pack update

Danilo Milenkovic

Part Number: CC3100

Greetings TI,

I have updated firmware on my CC3100MOD via Host Programming.The service pack I used was the latest one from your webpage (1.0.1.11-2.9.0.0) .

I have basically just followed instructions from these page. The formatting string used was the 8MB one. The service pack programming code was pretty much copied.

The two host programming headers were included in the host application. The host performs serial flash formatting and service pack programming with no error reported.

After the update my host application won't work properly anymore. It passes the first sl_Start() successfully.

After that,calling sl_DevGet() returns that the new firmware version is 1.4.0.1 (previously it would return 1.2.0.2). However once it resets the device by calling:

sl_Stop(100);

sl_Start(0, 0, 0);

it gets stucked in sl_Start. The same code worked before the update. Can you tell me if I've maybe overlooked something about the pack update procedure.

I'm using SimpleLink API from 1.2.0 version of CC3100SDK. Is it compatible with the latest service pack?

Please help

Hi,

Can you please provide NWP logs for this?

Apologies,but that site reports it is experiencing technical difficulties.
Could you please post how to capture them here?

Also,could you please send me the service pack with the 1.2.0.2 version of firmware (the one that worked) so I may know
if my host programming is working properly?

Kind regards

Please,

I haven't managed to solve these problem yet. Could you at least confirm to me that 1.2.0 version of SDK
is compatible with 1.4.0.1 service pack? The SL_DRIVER_VERSION from simplelink.h is 1.0.1.6 and it's confusing.
If sl_DevGet() returns 1.0.3.25 as device PHY after update is the service pack ok? Could you give me the 1.2.0.2 service pack?
Anything,please,it's important.

Hi Danilo,

Sorry for the delayed response.

The latest SDK should work with the latest service pack.

I printed the linked wiki, see PDF below. Can you please provide the logs

Hi Charles,

CC3100Update.zip

You will find UART and SPI logs from update in attachment.

I didn't use either the Emulator Board or the MSP Launch Pad,

but the logic analyzer,so I hope the files are ok.

The spi logs use channel 1 as HOST_INT and channel 2 as nHIB.

StartPass file is from the first start (the one that's ok).

StopStart is from the restart after update (sl_Stop and slStart where it gets stucked in _SlDrvSyncObjWaitTimeout).

One more thing, if you look at MOSI line at the end of spi communication in WriteServicePack file you will

find that when the image signature is being written the last bytes of the signature have values different from

those in the array from host_programming_1.0.1.11-2.9.0.0_ucf-signed.h. Is that as it should be or not?

Regards,

Danilo

I may be onto something. It seams than my device initialization flow in sl_Start was bad.

It might have been a coincidence that it worded with the previous version of firmware.

What interests me is these. Could you be more exact about the initialization flow?

When is the nHIB pin asserted? When is the HOST_IRQ driven low and when is it asserted regarding to sl_lfOpen, sl_DeviceDisable, sl_lfRegIntHdlr and al_DeviceEnable?

In particular what should be done in sl_lfOpen function?

Kind regards,

Danilo

Solved the issue. Interrupts needed to be disabled on host in sl_lfOpen.
Otherwise HOST_IRQ interrupt would be received to early during initialization.
