WICED Studio Wi-Fi Combo

Greetings,

I am using an evaluation board with the Murata SN8200. I want to run the snip.scan application. I have renamed the file on the make target tab to snip.scan-BCM943362WCD2-debug download because the SN8200 uses the BCM943362WCD2 platform. When I am debugging the application i am getting the following Error:

No source available for "_tx_thread_system_return() at 0x...."

The problem is in the wiced_management_wifi_on() function. To be more specific the program crushes when it tries to successful run the wiced_bus_init() function wich is within the wiced_management_wifi_on(). The debugger is not easy to follow, so i do not understand at which point of the wiced_bus_init() function, the error pops up. I have changed the country code to Ireland as well because it was USA.

Best Regards,

Asterios

Hi Asterios,

BCM943362WCD2 platform is designed to work with BCM943362WCD2 eval board. It partially works with SN8200 because it probably has STM32F1xx series MCU built-in as well. I suggest you contact Murata to get the exact details and platform files for SN8200.

Hi Asterios,

_tx_thread_system_return() function is a ThreadX function and ThreadX is delivered in library format only, which is why the IDE can't find the source file.


When you run the debugger, does it break/halt? If it does, you should look for and expand the thread that is ready. It normally shows as 'Thread xxxxxxxxx (app_thread::Ready) (Suspended::Breakpoint). Expanding the call tree and double clicking on the topmost function will take you to the code where it breaks.

Greetings Aji,

Thank you very much for the advice. I have tried to track down the Fault and i noticed that i get a WICED_TIMEOUT from the host_platform_sdio_enumerate() function. The comments of this function say that if you get a timeout maybe the platform that you are using does not correpond to the actual hardware. However, I use the BCM943362WCD2 platform which is the correct one for the SN8200 Murata module. This is what I read on another thread in this forum at least, and it is the only platform that gives me output to the UART.

Best Regards,

Asterios

Greetings Aji,

Thank you very much. I came in touch with Murata. In order for the WICED IDE to be able to work properly with the SN8200 module, I had to register the module on Murata's website, log in to their forums with a password that they sent me, and download a patch which I had to apply on the IDE.

Best Regards,

Asterios
