I keep getting SDIO driver init failed

[EricLin0123]

I am using AzureWave AW-AM510-uSD and i.MX RT1060 EVK board to try out the evkmimxrt1060_wifi_cli SDk example project. I have go to "/source/app_config.h" and declared the module:

 #define WIFI_IW416_BOARD_AW_AM510_USD

then hit build and debugged it. In Tera term I keep getting the following message:

[sdio] Error: Card initialization failed
[wifi_io] Error: SDIO driver init failed.
[wifi] Error: sd_wifi_init failed. status code -1
[wlcm] Error: wifi_init failed. status code -1
ASSERT ERROR " 0 == result ": file "main.c" Line "278" function name "wlan_driver_init"

I am pretty sure I got all the SDIO connection and antenna right.

Thank you for reply.

I had the same problem. Though I am using RT 1020 and AzureWave model is slightly different. But might be the same reason we are facing this issue. So I am posting it. Sorry, if I am wrong.

Initially thought that the AzureWave wifi module was not attached well (that had happened before). But it is the jumper position.

Check out the user guide of the AzureWave mode.

In my case it is mentioned that I need to change the jumper position of J2 to 1-2.

>For SDIO supply VBAT, please connect J2(1-2)

After changing the jumper position, it works fine.

Hi @EricLin0123 ,

   Please check the SDK document for the hardware configuration at first:

SDK_2_13_1_EVK-MIMXRT1060\docs\wireless\

UM11441-Getting-Started-with-NXP-based-Wireless-Modules-and-i.MX-RT-Platform-Running-on-RTOS.pdf

chapter 4.2.3 AzureWave AW-AM510 module

Please check your module settings at first.

BTW, please use the newest SDK version instead of the old version.

If you still have issues, please also give me the connection photo, and used SDK version, then I will try it on my side.

Best Regards,
