unable to bootup CYW4373 (2BC/2AE) with STM32L4R9.

Hi

I'm using STM32L4R9 (I have L4R9I-Eval and on my custom board I am using STM32L4S9ZIJ6) with CYW4373 (I am using EAR00436 and its uSD Adapter, which use 2BC module from Murata which is also mounted directly on my custom board), with ThreadX and NetX Duo. I am configuring the driver on STM32Cube IDE and using the Manage Software Packs in IOC file viewer and selecting Infineon Wi-Fi Drivers with the below specs:

I connected the module on the uSD slot on the devboard using uSD adaptor and followed the guide here(point 8 in this guide). I'm unable to boot up the WiFi module this way, I am encountering the following error:

chip ID: 17267
whd_bus_sdio_cmd53:1088 cyhal_sdio_bulk_transfer SDIO_BLOCK_MODE failed
whd_bus_sdio_download_resource: Failed to write firmware image

0004 00:00:29.160 Error in initializing primary interface !!

0005 00:00:29.180 Error : Initializing Wi-Fi interface

Then I tried by removing the power supply to the uSD Adaptor and plugging it back in during WiFi initialization, which allows for a successful boot-up. Below are the logs:

This is for boot up. After bootup (using 2nd method), I was still unable to connect the Module to a given access point(in this case my mobile hotspot). I think the module is connecting to wifi but not getting an IP address and on the mobile it shows a device is connected but fails to get any device info . Following are the logs in this case:

Please Help me with the boot up issue and connect Wi-Fi module to given access point.

Hello @_uttam ,

After checking the Infineon/AIROC github repo you can see that the STM32L4 series of MCUs including STM32L4R9 are not supported for your module.
