Wi-Fi Bluetooth for Linux Forum Discussions

Our embedded design is based on the Murata WiFi+BT 1DX module with the CYW4343W chipset.

We are using Linux 4.9.x LTS, not Yocto.

Can anyone please point us to where we can find the latest firmware for the mainline kernel?

Additionally, do we need separate drivers for this to work?

If so, can someone point us to where we can find those?

Thanks.

Hi to everyone. I have problem with firmware crashing when using IPv6. I don't know what is correlation with ipv6 protocol and wifi but I can reproduce crash  when following same setup settings. If I use ipv4, crash never occurs (wifi interfaces can have 5 days uptime), but when I enable ipv6 (it doesn't metter if I use radvd or dnsmasq for RA) fw crashes...

A couple of infos:

I use netgear router R8000 (BCM43602/1) with DDWRT fw on it. On dorum they told me that ddwrt uses brcmfmac and Cypress fw. Infos I founded with dmesg:

driver and fw ID: Jun 12 2022 22:08:58 version 7.49.6 (r588839) FWID 01-f458629d

and here is the crash:

Can you help. I tried to contact ddwrt devs with no success...

Thank you for any info in advance....

I have build bcmdhd.ko and execute insmod successfully , as attach log, 

mmc devices already shows under /sys/bus/sdio/devices/

$ls /sys/bus/sdio/devices/

mmc0:0001:1 mmc0:0001:2 mmc0:0001:3

But wlan0 interface was not created,
it will shows ifconfig: SIOCGIFFLAGS: No such device when I execute "ifconfig wlan0 up",

I didn't see any error message, Could someone help to fix this issue? Thanks a lot.

Hi Team,

We are working on iMX8M Mini SoC with Android 11 OS support. We have integrated CYW43455 chip, BT and Wi-Fi are working fine. We need to perform RF testing.

We are using wl binary for Wi-Fi and HCI binaries for BT RF testing on cyfmac43455-sdio.bin (WLTEST) firmware version.

We are facing below issues:

Wi-Fi:

While running tests on 5GHz band (band a), it is giving an error while choosing the channels in the mid-band (52 to 140) and high band (184 to 216) as shown in the image below.

The other channels (36-48 & 149-161) are working fine.

Is there any specific firmware file that we need to use for Wi-Fi RF testing.

BT:

We followed below steps for BT continuous wave transmit test:

1. Turn on BT Snoop log in developer options.
2. Turn on BT using display.
3. adb port forwarding 8872 and 8873.
4. adb reboot.
5. After reboot, adb shell.
6. HCI_Reset and enter.
7. Set_Tx_Carrier_Frequency_ARM and enter.
8. Type 00 02 01 00 09 00 00 and enter.
9. Program returned done.

In our spectrum analyzer we are not able to observe the continuous wave. i.e.,CW tone is not being transmitted.

steps followed for BT Packet transmission test:

1. Check BT Snoop log in developer options is turned on.
2. Turn on BT using display.
3. adb port forwarding 8872 and 8873.
4. adb reboot.
5. After reboot, adb shell.
6. HCI_Reset and enter.
7. Tx_Test and enter.
8. Type 66 55 44 33 22 11 01 00 04 01 0F 00 00 09 00 00 and enter.
9. Program returned done.

In spectrum analyzer we are not able to observe the BT packets. i.e., packet transmission not happening at 2402MHz.

Please find attached BT snoop logs for all the RF testing.

Do we need to set board specific BD_ADDRESS while sending packets from device and how we can observe that packets are transmitted or not without data loss.

Thanks,

Kaushal Verma

Hi,

We are trying to use Murata Type 1YN module for implementing LWM2M client. We would like to use  Zephyr rtos. Do we have zephyr support for this .

Hi

We need help in bringing up BLE Mesh on CYW43012 module on Linux platform.

From the comments of the below link I find that you will be providing support for BLE Mesh on Linux platform for CYW43455 at the end of 2020.

https://community.infineon.com/t5/Wi-Fi-Bluetooth-for-Linux/BLE-MESH-support-on-CYW43455-using-Bluez-v5-52-on-Linux/m-p/222493

Below is the message snippet:

"

Hi,

Thank you for providing the details.

Currently, we do not have a ready solution available. But, we have a plan to support it, hopefully towards the end of the year.

Thanks,

-Dheeraj

"

Is there any update on this?

Can you please help us with the bring-up of BLE Mesh on CYW43012/CYW43455?

Hello,

Currently we are using the dhd-android-1.363.125.17 for wifi and bluetooth in cyw43438. We will porting from android 9 to android 11. We need support for the new drivers for this chipset cyw43438

For emissions testing, I am trying to use the wl tool with NVIDA Jetson TX2, which has the BCM4354. I received a wl64 executable and 4354’s mfgtest firmware from an Infineon Tech Support Case.

I believe I correctly installed the mfgtest firmware by replacing /lib/firmware/brcm/fw_bcmdhd.bin with cyfmac4354-sdio.bin and by moving cyfmac4354-sdio.clm_blob to become /lib/firmware/brcm/bcmdhd.clm_blob. Before the above changes, running “sudo ./wl64 ver” gave me:

1.28 RC0.0
wl0: Jul 21 2020 16:35:45 version 7.35.349.94 (r726700 CY) FWID 01-aa356e32

After installing mfgtest firmware, the wl ver command gave me:

1.28 RC0.0
wl0: Sep  1 2021 02:23:00 version 7.35.349.112 (ae8cc29 CY WLTEST) FWID 01-6e1af42a

My main problem is that wl64 can’t bring up the Wi-Fi after I use it to bring down the Wi-Fi. It also doesn't work using the original firmware (i.e., before introducing the mfgtest firmware). The following are the commands I ran and the output.

user@device:~$ ip -br address show wlan0
wlan0            UP             192.168.0.79/24
user@device:~$ sudo ./wl64 down
user@device:~$ ip -br address show wlan0
wlan0            DORMANT        192.168.0.79/24

(after ~20 seconds)

user@device:~$ ip -br address show wlan0
wlan0            DORMANT
user@device:~$ sudo ./wl64 up
user@device:~$ ip -br address show wlan0
wlan0            DORMANT

At this point, I also can’t use the GUI to connect to a Wi-FI network.

Have I done anything wrong? What do I do so that I can at least use the wl tool to bring down and up the Wi-Fi module?

Hi Infineon Team,

We are using CYW43455 WiFi chip on iMX8MMini processor with Android 11 OS.
We want to operate only on 2.4GHz band i.e should not connect to 5GHz APs.

How and where to do this change in code?

Thanks.
