Wi-Fi Bluetooth for Linux Forum Discussions

Hi ,

We are using CYW43455 chip as WIFI STA. We find this module can't discover the AP which is set to WPA2 TKIP only. So, I want to check whether this chip support WPA2 TKIP. 

OS: Linux 4.9.69

Driver and FW: cypress-fmac-v5.4.18-2020_0402

WL version: 7.45.206

could anybody help to clarify this?

thanks,

Johnny

Hi!

I'm representing Conclusive Engineering we are creating a custom board that utilizes CYW4343WKUBG chip for WiFi and Bluetooth connections. Based on public documentation the chip in the WLBGA package was directly embedded in the board design. Connection to the main CPU is made using SDIO for WLAN and UART for Bluetooth.

Our current status is having the chipset detected on the SDIO bus and the Linux kernel module tried to start the hardware by loading firmware files. We are based on a 5.8 kernel version and Buildroot based root file system.

We have a problem with bringing up of the CYW4343 chip. What we are missing is the firmware package for the chip and
NVRAM settings file. While I've found some firmware files in linux-firmware.git repository I don't know where should I get proper NVRAM settings text file and if some correlation between the firmware and nvram file exists.

Thank you for your support.

Best,Marcin

Hi Sir,

我在调试43455的时候，在加载FW出现error，导致DHD 加载失败。

我使用的环境是IMX.8的平台，arm64，Linux4.18，DHD版本125.15~125.19都有验证过，海华197（43438），288（43362），256（43455）EVK，其中197,288都可以正常工作，256在以上所有版本驱动都出现FW加载失败的问题，理论上来说43438与43455共用同一版驱动没有问题的，也怀疑过可能是256EVK本身的问题，用FMAC验证256EVK是可以正常工作的，所以现在比较疑惑，请帮忙分析下，谢谢。

以下是256加载驱动时的dmesg log，其中一份是通过256EVK的SD口供电，另一份是256EVK的USB口供电。

Hello,

  We have custom board with a 43012 connected via SDIO to a Xilinx ZynqMP.    We are using the latest Xilinx release which run the 5.4.0 kernel.   Based on information in the v5.4.18-2020_0625 version of the backport driver and cypress-yocto-scripts I have added support into yocto to build everything.

  I am using the following firmware/nvram files:

BCM43012C0_003.001.015.0102.0141.1LV.hcd*  brcmfmac43012-sdio.1LV.txt  cyfmac43012-sdio.bin  cyfmac43012-sdio.clm_blob

I get the timeout error so the wlan0 interface is never created.

Based on the kernel logs the chip is powered up and the driver can talk to it.

======================================================================

It appears that the firmware is loaded and the nvram.  However, after the nvram is loaded and this code from brcmf_sdio_htclk is executed I get the timeout error.

/* Otherwise, wait here (polling) for HT Avail */

timeout = jiffies +

  msecs_to_jiffies(PMU_MAX_TRANSITION_DLY/1000);

while (!SBSDIO_CLKAV(clkctl, bus->alp_only)) {

  clkctl = brcmf_sdiod_readb(bus->sdiodev,

   SBSDIO_FUNC1_CHIPCLKCSR,

   &err);

  if (time_after(jiffies, timeout))

    break;

  else

   usleep_range(5000, 10000);

  }

  if (err) {

    brcmf_err("HT Avail request error: %d\n", err);

    return -EBADE;

  }

  if (!SBSDIO_CLKAV(clkctl, bus->alp_only)) {

    brcmf_err("HT Avail timeout (%d): clkctl 0x%02x\n",

      PMU_MAX_TRANSITION_DLY, clkctl);

   return -EBADE;

}

It looks like the the code is trying to re-initialize certain things after loading the nvram and what looks like a status register, SBSDIO_FUNC1_CHIPCLKCSR, has an error it it.

Any ideas of what could be happening here?  Is this process trying to switch from an internal to external clock?   We do have an external osc. connected to EXT_LPO.  I know it's unlikely, but is there any available documentation that would describe SBSDIO_FUNC1_CHIPCLKCSR?

thanks

Hi,

I'm 

I followed the instuctions on page 3 of WICED™ Manufacturing Test User Guide

Now I have a problem when I enter the command to "sudo ./wl -i wlan 0 out"

and then "sudo ./wl -i wlan0 fquacurcy 6"

No matter what wl conmmond I enter, the device keeps reporting errors.

Is the problem with "wl out"?

Hi ,

We are integrated CYW89820BWMLGT BT module along with our imx6 based processor. So we wanted to program the module with the BT stack. Can you please let us know whether the default module will have some of the BT stack or is it required to flash the module .

If Flashing is required  then i have refereed the WISED HCI UART Protocol on downloading the application to serial flash. when downloading the serial flash will the stack also get written to the FLASH ?

What is start address of the FLASH to which the application can be written.Will the flashing process work on a new module?

Please let us know the above details ASAP.

Thank you,

Deepanraj.A

Hi,

where can I find the most recent version of wl_tool ?

I have downloaded the one from this post but it seems to not integrate all the commands (phy_watchdog is missing for example).

Where can I download a more recent version?

Thanks,

we have integrated the cypress chipset in our PCBA with our Host processor (Device: Cortex-A7) and we booted the device. I got the attached Manufacturing test firmware  files(cypress-mfgtest-v5.4.18-2020_0402.tar.gz) from murata support team. Placed the firmware files in /lib/firmware/brcm of our linux file system and we could see during the boot up of the device we observed below logs
