Does the driver brcm43430 / cyfmac43430 support setting bitrates with iw?

I'm getting the following error when trying to force valid bitrates for a variety of brcm43430-sdio.bin / cyfmac43430-sdio.bin driver versions (7.45.98.38, 7.45.98.94, 7.45.98.97).

$ iw wlan0 set bitrates legacy-2.4 18 24 36 48 54
command failed: Not supported (-95)

Falling back to the default set produces the same error:

$ iw wlan0 set bitrates

command failed: Not supported (-95)

Trying to add WPA3 for BCM4359, but wpa_supplicant will fail to start if ieee80211w was set to 1 or 2.

We suspect the driver we have may not have PMF support, is there a way to check?

The .config for compiling is attached.

The configuration for wpa_supplicant is:

network={

ssid="HelloWorldWPA3"

psk="VeryCoolPassword"

proto=RSN

key_mgmt=SAE

group=CCMP

pairwise=CCMP

mode=2

frequency=2412

ieee80211w=2

}

Hi Team,

I added the CYW43455 WIFI/BT chip support in the Jetson Platform using the following driver/firmware Cypress Linux WiFi Driver Release (FMAC) [2020-09-25]

Wi-Fi is working but it supports only 802.11 a/b/g modes. And I am not able to use 5Ghz in AP mode.

1) How to add support for 802.11 n/ac modes?

2) Does 802.11 n/ac support added by firmware or any other layer of WIFI interface?

3) Is there any procedure/commands to verify the 802.11 ac mode?

Thanks,

Ajith.

Hi Team,

I’m using CYM43455 module with the customized board and Jetson Xavier NX SoM.

When I try to do hciattach command, first few times the command is not working.

$ sudo hciattach /dev/ttyTHS0 bcm43xx

It gives the below errors.

bcm43xx_init
Failed to reset chip, invalid HCI event
Can't initialize device: Success

bcm43xx_init
Initialization timed out

Tried increasing timeout using argument -t in hciattach too.Still Initialization times out.

When the hciattach command is given repeatedly, after few attempt, the command works.

$ sudo hciattach /dev/ttyTHS0 bcm43xx

bcm43xx_init
Set Controller UART speed to 3000000 bit/s
Device setup complete

Can you please help in finding the cause of this issue?

I'm trying to test the cyfmac54591 module with an NVIDIA Jetson Nano, and running into an issue with loading FW during 'insmod brcmfmac.ko' :

from dmesg:

I've compiled the kernel modules (compat, cfg80211, brcmutil, brcmfmac) on the Jetson Nano using sources from cypress-backports-v5.4.18-2020_0925-module-src.tar.gz, and copied the contents of cypress-firmware-v5.4.18-2020_0925.tar.gz to a new folder /lib/firmware/cypress.  I modified the kernel config file as described in the README in order to prevent error during 'insmod compat.ko'  

I don't see any .txt files in my /lib/firmware/cypress folder, is there a way to specify which FW file to use, or am i supposed to generate the .txt file somehow?

Hi 

our team has to build sama5d3_xplained based board currently we are stuck in the wifi+bt section.

we are using the "Cypress CYW4343W" chipset below link given.

link https://wireless.murata.com/type-1dx.html

We are using buildroot-at91 (https://github.com/linux4sam/buildroot-at91).

we try to integrate wifi+bt with SAMA5D3 but we do not get any solution.

now, what steps needed in the Linux kernel to get WiFi+Bluetooth in life.

thank you
