We would like to support WPA3 Enterprise and AES-192 modes by CYW4373 using murata Type 2BC.
Using bindings for Linux driver is as below for Infenion CYW4373.
https://github.com/STMicroelectronics/linux/blob/v6.1-stm32mp/Documentation/devicetree/bindings/net/wireless/brcm,bcm4329-fmac.yaml

Are all Enterprise security modes supported that are listed by wpa_supplicant here?

Infineon strives to enhance user experience by providing *ease-of-use* Software for swift activation of the AIROC Wi-Fi/Bluetooth combo.

This guide outlines the steps for Debian package installation on the NVIDIA Jetson Orin AGX + CYW55573 board to enable the WLAN module in just a couple of minutes.

NVIDIA Jetson Orin AGX + CYW55573 Debian Package Bring-Up Steps

• Introduction

             The steps outlined in the document describe how to install the Debian package in order to enable the WLAN module on the Jetson Orin AGX platform.

• Pre-requisite

             Ensure that the default kernel image from NVIDIA Jetpack 5.1.2 with kernel version 5.10.120 is installed.

             Jetpack SDK 5.1.2: https://developer.nvidia.com/embedded/jetpack-sdk-512

             Once this requirement is met, proceed with the following instructions.

•     Hardware
  1. Jetson Orin AGX board
  2. CYW55573 M.2 module

• Debian package bring-up
  1. Install the package cyw55573-jetson-orin-agx-1.0-1-arm64.deb using the command:

•              % sudo dpkg -i cyw55573-jetson-orin-agx-1.0-1-arm64.deb

•  

  2. Use the following command to check if the wlan0 interface is available:

               % ifconfig

   

• 

                     c. To assign a static IP address to the wlan0 interface, use the command provided below:

                          % sudo ifconfig wlan0 192.168.147.25 up

                     d. The IP address subnet should match that of IP address of AP. Once you have assigned an IP address, check the output of the ifconfig command.

We have spotted a path correction to the script that was used for Debian package (Firmware/FMAC) creation and so we updated/fixed that script.

Using this updated script we created the deb pkg, there are no any firmware/FMAC files changes in this deb package.

There're 2 *.deb packages been attached:

1. cyw55573-jetson-orin-agx-1.0-1-arm64.deb --> Fmac driver, firmware pkg Debian file.
2. ifx-hostap-jetson-2.10-arm64.deb --> hostapd, supplicant pkg Debian file.

Feel free to leave your comments here if you run into any problem.

2022-06-07 Initial Post

Hello,
We have a custom hardware board based on STM32MP1 mpu along with cypress43455 and some other peripherals too.
For our use case, we are using yocto linux and uses openstlinux (arm-openstlinux_weston-linux-gnueabi-gcc), Kernel version 4.19.9 . We used to get the kernel oops message and the network crashes when I copy files bigger than 1MB from the target to host (https://community.infineon.com/t5/AIROC-Wi-Fi-MCUs/The-Network-Crashes-while-transferring-files-over-WiFi-Need-Backports-for-kernel/td-p/462819 ).

So we decided to use the latest backport drivers, and downloaded the latest cypress linux WiFi driver release [ cypress-fmac-v5.15.58-2023_0801 ] ( https://community.infineon.com/t5/Wi-Fi-Bluetooth-for-Linux/Cypress-Linux-WiFi-Driver-Release-FMAC-2023-08-01/td-p/459849 ).

We successfully compiled the drivers from the backport  as per the software user guide.

And for the firmware, since those were missing in the recent releases, used the cyfmac43455-sdio.bin and cyfmac43455-sdio.clm_blob files from 2022_0511 Release from https://github.com/Infineon/ifx-linux-firmware/tree/dc38e700612b334080e0b6df69070a88c4c2a12b/firmware . 

For the nvram file cyfmac43455-sdio.txt, we got it from murata ( https://github.com/murata-wireless/cyw-fmac-nvram/blob/master/cyfmac43455-sdio.1MW.txt )

We copied the new driver files and all the above mentioned files and booted the target board, but, the WiFi interface (wlan0) itself is missing.  There is no network.

We couldn't find what is wrong. We are stuck at this problem. Could you please help us

solve this problem ?

Hi:

I'm using CYW55573-SDIO/AW-XB583MA-SUR with brcmfmac 5.15.58-20230901 on Rock 5B. I cannot reload driver, showing brcmf_blhs_is_bootloader_ready: Timeout waiting for bootloader ready.

The only way to solve this is de-asserting WL_REG_ON and re-asserting it.

Full log & dts & nvram is on attachment.

Fw version: wl0: Jul 31 2023 23:59:17 version 18.53.212.15 (2203c7e) FWID 01-ca141bb2

These commands can reproduce this bug.

insmod brcmfmac.ko debug=0x00100007 ; sleep 1 ; rmmod brcmfmac ; sleep 1 ; insmod brcmfmac.ko debug=0x00100007 ; dmesg > log

Is there any solution to fix this, keeping WL_REG_ON always active?

I tried CYW43455-SDIO and this problem does not happen.
