Wifi driver problem in L4.1.15

Hi,

I am using murata SN8000 wifi module with sabre quad board.

The driver module in L3.14.52 works fine.

I used "modprobe bcmdhd firmware_path=/lib/firmware/bcm/SN8000_BCM43362/fw_bcmdhd.bin nvram_path=/lib/firmware/bcm/SN8000_BCM43362/bcmdhd.SN8000.SDIO.cal dhd_msg_level=0x1" to install the module.

Now, I switched to L4.1.15 with the same board.  I was using the original zImage and device tree(zImage-imx6qdlsolo.bin and zImage-imx6q-sabresd-btwifi.dtb).

This time the module is built in the kernel, but I always get an error "CFG80211-ERROR) wl_event_handler : was terminated"

Hello Ivy,

I cannot understand your question in below. If you use fsl kernel branch L4.1.15 than you have to set kernel configurations for example firmware path and nvram path for built-in wifi module. Moreover it needs to change sdhc configurations in device tree as well.

"Now, I switched to L4.1.15 with the same board.  I was using the original zImage and device tree(zImage-imx6qdlsolo.bin and zImage-imx6q-sabresd-btwifi.dtb)"

Hi Hung,

The problem I got before was because I was using the target image that built in the package.

But this image does not have WEXT support which need for murata SN8000 wifi module in it.

Therefore, I got the Kernel source code, enable WEXT support(CONFIG_WEXT_CORE and CONFIG_WEXT_PROC) and rebuild it.

Then it works.

I hope this can help you.

Best Regards,

Ivy

Hi Ivy,

   Seems that enabled WEXT cant help my problem, I would appreciate it if you can provide the dmesg/log during the wlan0 up for work kernel.

Hi Igor,

Could you please help me to post? I can not find any link or something to allow me to post.

And could you please help to ask how to get fw_bcmdhd.bin and bcmdhd.SN8000.SDIO.cal for L4.1.15?

Now I only can find them in L4.1.15-1.0.0 and L4.1.15-2.0.0.

Thank you very much!!

Ivy

Hello Ivy,

I don't think wifi module has any problem since interface wlan0 register successfully.

And if this is the case you might use 

"ifconfig wlan0" check register interface

"ifconfig wlan0 up" active wlan0 interface 

And if wlan0 is up then you can try to use wireless tools "iw" for setting connection with AP

Meanwhile I've noted your bcmdhd version is "1.141.92". As I know the latest stable version within kernel 4.1.15 bcmdhd version is "1.141.88" and I'm not sure if this cause any other problem.

hope this helps,

Hi Karl,

I can not configure wlan0.

Is the wrong bcmdhd.bin file used here, why wl_android_wifi_on() get called when I am using Linux?
