Any 88W8987 example for Type 1ZM WiFi module

[prof__paradox]

The MIMXRT1064 is a host controller connected to Murata's LBEE6ZZ1PY which is an 88W8987 based WiFi module. The wifi examples in MCUXpresso are for AzureWave's AW-CM358MA module which is also 88W8987 based. I just want to know whether those examples can work with Murata's module which is based on same chipset. Thanks!

Hi @prof__paradox 

   If your module is also the 88W8987 which is the same as AW-CM358MA.

  Then you also can use the SDK related code, just check your module related pin, whether it is the same as AW-CM358MA.

  As I know, the SDK code can works for the 88W8987, in the code, change the macro to WIFI_88W8987_BOARD_AW_CM358MA.

Wish it helps you!

Hello @kerryzhou , I checked the connections and they seem to be good. And I also included the macro WIFI_88W8987_BOARD_AW_CM358MA. I am getting "SDIO driver initialization failed" message in the debug console. Any idea what might be messing up?

Hi @prof__paradox ,

  Check the module voltage configuration, as I know, the AW_CM358MA also have the settings, you can check the SDK related code readme:

Jumper settings for AzureWave AW-CM358-uSD Module:
- J2 1-2: 3.3V VIO_uSD (Power Supply from uSD connector)
- J4 1-2: VIO 1.8V (Voltage level of SDIO pins is 1.8V)

The hardware should be reworked according to the Hardware Rework Guide for MIMXRT1060-EVK and AW-CM358-uSD in document Hardware Rework Guide for EdgeFast BT PAL.
The pin connect for UART HCI as the following table,
------------------------------------------------------------------------------------
PIN NAME | AW-CM358-USD | I.MXRT1060 | PIN NAME OF RT1060 | GPIO NAME OF RT1060
------------------------------------------------------------------------------------
UART_TXD | J10(pin 4) | J22(pin 1) | LPUART3_RXD | GPIO_AD_B1_07
UART_RXD | J10(pin 2) | J22(pin 2) | LPUART3_TXD | GPIO_AD_B1_06
UART_RTS | J10(pin 6) | J23(pin 3) | LPUART3_CTS | GPIO_AD_B1_04
UART_CTS | J10(pin | J23(pin 4) | LPUART3_RTS | GPIO_AD_B1_05
GND | J6(pin 7) | J25(pin 7) | GND | GND
------------------------------------------------------------------------------------

So, your replaced module also need to use the same configuration and voltage.

Okay, Thank you very much!

I'll recheck everything that you said and update you on the progress.
