Hi,

We require your help for below commands to run for our Module certification.

WiFi:

• Packet Error Rate Calculation in Rx Blocking Mode Test

BT:

• Change Data Pattern: Require to send customized data pattern.
• Bit Rate Error Calculation for Rx Blocking Mode Test
• Modifying BT Tx Power: Commands to SET/GET Tx Power

BLE:

• Default Tx Power: Commands to SET/GET Tx Power

Here are the software version details:

Hello,

I have ported the last release of FMAC drivers into my IMX8MQ board

following the instructions on the related README.

The CYW43455 WiFi module is interfaced to the IMX8 through a SDIO.

When the brcmfmac driver is insmod-ed, a "platform not found" message is printed.

Nevertheless, the init of the drivers goes on and is concluded without errors.

The driver is shown in the lsmod module list.

However, the sdio probe function doesnt' seem to be called (no related printings)

and the wlan0 device has not be created:

# ifconfig wlan0 up

ifconfig: SIOCGIFFLAGS: No such device

Have you any suggestions/explanations for this behaviour?

Thanks

Hello to everybody,

what are the kernel drivers to be used for CYW43455 (for IMX8MQ) ?

I've downloaded FMAC, but it seems to patch only Wireless LAN drivers.

Thanks

Hi

I use 1DX(CYW4343W) module which is included BD MAC Address by Murata.

But all board indicate 43:43:A1:12:1F:AC of the MAC.

I found same case, but the solution is How to set the arbitrary address.

<https://community.cypress.com/message/32945#32945>

My question is how do I set BD MAC Address to the module assigned address.

Our design is:

Module:Murata 1DX (with BD Address tyep) (CYW4343W)

Linux :rel_imx_4.9.88_2.0.0_ga

Driver:meta-murata-wireles 4.14 mothra

Thanks!

I need Declaration ID of Controller Stack for Bluetooth certification.

How do I get it ?

I have Module's ID and Host Stack's ID, but I cannot find Controller Stack.

Our design is:

Module:Murata 1DX(CYW4343W)

Driver:meta-murata-wireles 4.14 mothra

Thanks,

Hello,

I was reading the thread BLE tx output power control in HCI mode and tested the proposed HCI_VENDOR_SET_TX_PWR command (0x01A5) on a chipset based on CYW4343W. However, it seems such command is not recognized/supported as per the logs I captured:

Therefore, my next question would be: is there any other specific command for this specific chipset that I may try to set the Tx power during a BLE advertising event?

According to the CYW4343W specification, it seems Bluetooth power control steps are available:

Thanks

Ricardo Bello

We now used cyw4339 and cyw43455, from murata,

driver:

https://github.com/murata-wireless/cyw-fmac/archive/cyw-fmac-imx-morty-manda_r1.0.tar.gz

fw:

GitHub - murata-wireless/cyw-fmac-fw

nvram:

GitHub - murata-wireless/cyw-fmac-nvram

can't find clm_blob file for cyw4339, cyw43455 have clm_blob file

Driver for two kinds of chip often print "brcmfmac: brcmf_parse_vndr_ies: invalid vndr ie. length is too small 4", but seems there isn't problem. Will it have some potential issues?

And also how to check if dfs enable/disable with wl?

Hi,

I need to run brcmfmac 43455 version 7.45.173  on my raspberry PI 3+ as it supports WPA3, When I install

brcmfmac43455-sdio.bin

brcmfmac43455-sdio.clm_blob

brcmfmac43455-sdio.txt

on my box I get the following dmesg

Do  I need a specific build for the Raspberry PI 3 +? Is there an image I can use.

Here is where I got the image from

Cypress Linux WiFi Driver Release (FMAC) [2018-09-28]

Thank for the help

I'm running in to a problem in Raspberry Pi 3 B+ running Kali Linux where WiFi controller freezes while in monitor mode, with the following error code under dmesg:

brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012

There are many people running in to this problem (based on the discussion thread below) but couldn't see any fixes from Cypress team. Can you please help?
