Wi-Fi Bluetooth for Linux Forum Discussions

Hi,

  I have an BCM4355 chip interfaced to SM32MP157 processor,both the drivers for WIFI/BLE are loading.But while running any operation on them I am facing issues.

WIFI Issues:

1.Both AP and STA mode are not running simultaneously at a time only AP mode is running.

2.If I run the wifi supplicant I was getting below errors

[ 1860.606056] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

BLE Issues:

On boot up I am getting below prints w.r.t Bluetooth

Bluetooth: hci0: command 0x0c03 tx timeout

Bluetooth: hci0: BCM: Reset failed (-110)

If I run the bluetoothctl tool I was returning below error

bluetoothctl

Agent registered

[bluetooth]# power on

No default controller available

  Can anyone help me how to fix these errors for my module.Thanks in advance.

Srikanth.

We are connecting CYW88359  W-Lan + BLE module on our set top box to BCM7628 PCIe interface via a PCIe switch instead of directly to the SoC as we need more than one PCIe connection. Does anyone have any recommendation or tips on how to best achieve this without compromising the performance (data throughput)?

Thank You.

hi

Is CYW89359 workable under NXP i.MX8QM Xen and OS Android™ P9.0.0_2.1.0-AUTO-ga

Hi ,

We recently tried to upgrade our 4.14.77 backports fmac driver to the latest 5.4.18 backports version.

The 4.14.77 backports was also being run on the 4.9 linux kernel and was working fine.

However when we tried to load the 5.4.18 package on the 4.9 kernel it fails with the highlighted error.

We have applied all the kernel configs suggested in the cypress readme so the build is successful but the driver load fails. See below.

How can we get past this issue?

Hi all,

  Our device we are working with v4.14.34-backports. Now recently I am trying to upgrade the driver using v5.4.18-backports drop. I get the following error.

Hi please can you provide the Preliminary Data Sheet for CYW4360 / BCM4360 chip? I cannot find it anywhere. Thank you

Hi,

Our product is unable to connect to WiFi channels 12 and higher. Out build is using the 1DX with v5.4.18-2020_0402 firmware and the latest Linux kernel supported by murata GitHub - murata-wireless/meta-murata-wireless  (branch imx-sumo-manda).

Using "iw get reg" this returns the country of the AP successfully. If the country is changed in the AP our product quickly follows suit. 

Using "iw list" shows all the channels that are enabled and disabled; these follow the selected country.

When GB is selected in the AP only channel 14 is disabled in iw list as you'd expect. However forcing the AP to use channels 12 or 13 fails to connect. It feels like the driver is stuck on US but is stating it's GB. 

If iw reg set GB and wl country GB are used after all this then it connects, but if beforehand the country was GB why set it again and why must both iw and wl be used?

Thanks.

Hi everyone:

    I am porting wifi module on my customed-board with imx8Quad chip,the board I am using is highly similar to imx8QuadXPlus. The wifi module is ublox JODY-W163 series,and I have succeeded in porting this wifi module on my board under yocto 4.14.78.1.0.0 project,but when I update yocto project to 4.14.98.2.3.0,the brcmfmac-sdio driver doesn't work as I expected.The main kernel dts changes can be seen in attached files .

when booting kernel ,the 4.14.78 log about brcmfmac-sdio driver shows below:

[    2.854654] mmc0: SDHCI controller on 5b010000.usdhc [5b010000.usdhc] using A

ffs.utp0[    4.125063] SDIO brcmf_ops_sdio_probe Enter-->   

whie booting kernel with yocto project 4.14.98.2.3.0,the log only shows:

[    2.197300] mmc1: SDHCI controller on 5b020000.usdhc [5b020000.usdhc] using A

After bring-up,the wifi modules(compat.ko cfg80211.ko brcmutil.ko brcmfmac.ko) are successfully insmod,but the wlan0 interface doesn't show up

How should I make wifi module detected by SDIO driver? Or any suggestions about which porting procedure may cause this problem?Any suggestion will be appreciated.

Hi Sir,

Hi Sir,

我用的平台是IMX6 ,LINUX环境，DHD driver，CYW43438运行在STA 模式。

目前考虑到功耗问题，想要通过调节DTIM的值，改变监听的间隔，从而达到省电的目的，但是在DHD driver里面改了一些参数，没有起到作用，也尝试通过wl dtim命令设置，发现在连接AP之后，DTIM会自动改变，应该是AP侧的DTIM值。

所以，想咨询下CYW43438在STA模式下，是否可以通过驱动修改DTIM值，如何修改呢？谢谢~
