WICED version : WICED-SDK-3.4.0-AWS

WiFi module : murata Type1DX (BCM4343W, SDIO interface)

I'm trying to port WICED framework onto a custom board.

Now WiFi firmware and nvram image seem downloaded successfully, but WICED doesn't work correctly yet.

I attached SDIO command log.

I noticed that getting MAC address and getting firmware version are not processed successfully.

I doubted around interrupt routing, but I couldn't solve it.

Can you point out the mistake?

Could you please enable wwd logging and share the wwd log?

The SDIO log is not clear and useful.

Also you can try to reduce the SDIO clock frequency.

What host MCU are you using?

Host MCU is Cortex-A9.

I know it is not supported MCU, but I think WICED will work if its BUS interface and interrupt handling are implemented properly.

Here are logs with WWD_LOGGING_UART_ENABLE in wwd_logging.h,

WPRINT_ENABLE_WWD_INFO,  WPRINT_ENABLE_WWD_DEBUG, and WPRINT_ENABLE_WWD_ERROR in wiced_defaults.h

Are you using OOB?

Can you please attach your nvram?

> Are you using OOB?

Yes. Following are codes about OOB interrupt. I set a breakpoint at sdio_oob_irq_handler, and I found the debugger stopped there. I attached a log file (putty20160425173334.log).

platform_config.h:

    #define WICED_WIFI_OOB_IRQ_GPIO_PIN  ( 0 )

platform.c:

    const platform_gpio_t wifi_sdio_pins[] =

    {

    #ifndef WICED_DISABLE_MCU_POWERSAVE

        [WWD_PIN_SDIO_OOB_IRQ] = {MCU_GPIO11, 10},

    #endif

        [WWD_PIN_SDIO_CLK    ] = {MCU_GPIO4, 14},

        ....

wwd_SDIO.c:

    static void sdio_oob_irq_handler( void* arg )

    {

      UNUSED_PARAMETER(arg);

      platform_mcu_powersave_exit_notify( );

      wwd_thread_notify_irq( );

    }

  

    wwd_result_t host_enable_oob_interrupt( void )

    {

      platform_gpio_init( &wifi_sdio_pins[WWD_PIN_SDIO_OOB_IRQ], INPUT_HIGH_IMPEDANCE );

      platform_gpio_irq_enable( &wifi_sdio_pins[WWD_PIN_SDIO_OOB_IRQ], IRQ_TRIGGER_RISING_EDGE, sdio_oob_irq_handler, 0 );

      return WWD_SUCCESS;

    }

  

    uint8_t host_platform_get_oob_interrupt_pin( void )

    {

      return WICED_WIFI_OOB_IRQ_GPIO_PIN;

    }

> Can you please attach your nvram?

I attach this file too. Type1DX_Final_nvram.txt is a base, and wifi_nvram_image.h is a converted file.

thanks.

Is the MAC address - FC:DB:B3:9E:47:BE - correct?

What is programmed to OTP?

I confirmed to murata's sales.

The formar "FC:DB:B3" in MAC address is vendor ID, so the function wwd_wifi_get_mac_address() seems to work correctly.

Can you get SDK 3.6.2 from muRata internal and run this again

And use the console app

The new console app has a "wlog" command that will get the log of the WLAN device and let us know if the FW is stuck somewhere

Thank you, nsankar. I will try it.

Is SDK version 3.6.2 correct? not 3.5.2?

Yes - correct. 3.6.2 is a private SDK release for specific customers, and muRata has access for this

I faced an another problem.

BESL is needed to build test.console application, but I'm trying to port WICED onto Cortex A9 platform. Of course, prebuilt binaries for CM3,CM4,CR4 are not compatible with CA9.

Could please you help me about this?  Can I get a prebuilt BESL library for CA9, or source code of BESL?
