MIMXRT1064-EVK + AW-AM510-uSD: wifi_init failed

sandeep_arm — Fri, 24 Sep 2021 18:51:20 GMT

Hi, I'm trying to use the "wifi iperf demo" with an MIMXRT1064-EVK + AW-AM510-uSD board. By following the instructions from https://www.nxp.com/document/guide/getting-started-with-nxp-wi-fi-modules-using-i-mx-rt-platform:GS-WIFI-MODULES-IMXRT-PLATFORM

However, I get the following error when running the example with the WIFI_BOARD_AW_AM457 define set:

======================================== wifi iperf demo ======================================== Initialize WLAN Driver [wifi_io] Error: Error in wlan_card_status() [wifi_io] Error: Card timeout wlan_download_normal_fw:361 [wifi] Error: sd_wifi_init failed. status code -1 [wlcm] Error: wifi_init failed. status code -1 ASSERT ERROR " WM_SUCCESS == result ": file ".main.c" Line "878" function name "task_main"

I have the jumpers configured as per the IW416 flow. It's also not clear if the WIFI_BOARD_AW_AM457 should also be used with AW-AM510-uSD modules.

Any suggestions?

Hello,

Could you please help me with the SDK version you are using ? Could you please help me confirm you are using the latest SDK available in the SDK builder?

Regards,
Estephania

Hi @stephanie_m,

Thank you for the reply!

I'm using v2.10.0 of the SDK_2.x_EVK-MIMRT1064, and installed in using the MCUXpressoIDE:

Is there a newer version available in the SDK builder?

Thanks,

Sandeep

Hi @sandeep_arm ,

I hope you are doing well. Could you please provide an image of your setup (i.MX RT1064-EVK and IW-AM510-uSD module) so we can look at all jumper configurations?

For IW-AM510-uSD, make sure jumpers are set as follow:

Depending on the module and application the EVK might require external power supply to support the initialization current peaks required by the module. Make sure the EVK is powered by external power supply using J2 barrel connector and J1[1-2] configuration.

Regards,
JC

Hi @jc_pacheco ,

Please see the attached photo:

Thank you for sharing the jumper settings of the IW-AM510-uSD module, I've set up mine the same way as you shared and also attached a external 5V power supply as you suggested. However, I am still getting the initializatnion error:

Hi Sandeep,

The jumper settings from your RT1064 look correct. I just double checked and corrected the jumper settings from wifi module, please see above. I'm attaching AzureWave AW-AM510-uSD User Guide.

There seems to be a problem when trying to download the firmware to wifi module... Could you please double check that the wifi module is correctly connected all the way in the uSD port?

I confirmed this configuration works with the RT1060... I don't have an RT1064 with me but I'll try to get one and test it.

Hi @jc_pacheco,

Thank you for the updated jumper settings, just set them up on my board and things are now working!

Will the documentation in section 1.2 of https://www.nxp.com/document/guide/getting-started-with-nxp-wi-fi-modules-using-i-mx-rt-platform:GS-WIFI-MODULES-IMXRT-PLATFORM - be updated accordingly?

Great news!!

Well, the section 1.2 from that guide is referring to the AW-AM457 as an example because there are several modules, we can't include them all
The required configuration should be available in each wifi module's user guide (in this case Azurewave's AW-AM510 User Guide).

Please let us know if you have any further question.

Ok, I still find it confusing as both the AW-AM457-uSD and AW-AM510-uSD are listed under IW416.

The AW-AM457 and the AW-AM510 are both based on the IW416 radio, but they use a different package (QFN vs. CSP respectively). From a firmware/driver perspective, there are no differences between these two modules. The difference is on the size of the module (as the CSP package is smaller), and on the price of the module.
