Question about wifi_cli example on IMXRT1170EVKB...

[EdSutter]

I'm working with SDK_25_03_00...

I installed a 2EL.M2 module from Embedded Artists.  The untouched example works as expected.

I've made a few modifications to change some functionality at the top level of the example, but I have not touched any of the WiFi-specific code.  So, as far as I can tell, the only change that the WiFi code sees is some memory map shifts.

With those changes, the wifi-startup never completes.  It consistently dies after 20 seconds in wifi_sdio_wait_for_cmdresp().  The last command function called from wlan_fw_init_cfg() is  wlan_get_value_1().  

I acknowledge that I did make some changes, but they aren't even close to this code.  I'm hoping someone may have some thoughts on why it is consistently timing out waiting for the response.

Hi,

What is the example you used and what are the exact modification you made?

It's the "wifi_cli" example...
SDK_25_03_00_MIMXRT1170-EVKB/boards/evkbmimxrt1170/wifi_examples/wifi_cli.
I added an Ethernet task.

Hi,

Thank you for the reply.

Unfortunately, we don't have a Wi-Fi + Ethernet example to use as guide. Perhaps there is a problem with the timings or memory that is causing this problem.

Have you tried initializing the Ethernet task after the Wi-Fi driver brings up?

The Wi-Fi and BT/BLE examples have very specific project settings to work correctly. If any setting is modified or causing conflict, the example functionality might be affected.

Regards,

Daniel.

Yes, I don't even start up the Ethernet task. So really the only thing that I think can be happening is that as the image changed, a buffer moved out of DMA space or non-cached area or something like that...
Thanks for checking. This is my bug, I just figured I would throw the question out to you guys for thoughts.
