CYW43455 is a Broadcom chip and not Marvell. The best would be to use Bsp 3.0 with Kernel Config WLAN_VENDOR_BROADCOM enabled.
Best regards,
Jaski
Hi @jaski.tx ,
OK,
Do I have to follow same procedure to use backport driver ?
or BSP3.0 (repo init -u Index of /toradex-bsp-platform.git -b LinuxImage3.0 -m default.xml) already has CYW43455 chip support?
Thank you
Neeraj
No, for Bsp 3.0, there are no backports anymore.
You can just customize your kernel.
Best regards,
Jaski
Hi @jaski.tx ,
I do not see any boardcom options in kernel config, with default kernel options with 3.0 kernel I mwifiex.ko is not available.

Did you use the toradex_4.14-2.0.x-imx kernel branch?
Hi @jaski.tx ,
Yes, that’s right.
git clone -b toradex_4.14-2.0.x-imx git://git.toradex.com/linux-toradex.git
Thank you
Neeraj
Thanks for your Input. If you do make menuconfig after doing make colibri_imx7_defconfig, then you can search for broadcom. The config for broadcom should be there.
Best regards,
Jaski
Hi @jaski.tx ,
I do not see that option.

You can search with / in menuconfig.
The driver is located here:
Symbol: WLAN_VENDOR_BROADCOM [=n]
│ Type : boolean
│ Prompt: Broadcom devices
│ Location:
│ → Device Drivers
│ → Network device support (NETDEVICES [=y])
│ (3) → Wireless LAN (WLAN [=n])
│ Defined at drivers/net/wireless/broadcom/Kconfig:1
│ Depends on: NETDEVICES [=y] && WLAN [=n]
Hi @jaski.tx ,
Thank you for pointing me the right option, I can get broadcom option to enable.
it seems still I am missing something.
I followed below:
repo init -u http://git.toradex.com/toradex-bsp-platform.git -b LinuxImage3.0 -m default.xml
bitbake virtual/kernel -c menuconfig
bitbake -k console-tdx-image

Hi @jaski.tx ,
Could you please suggest me on this?
Thank you
Neeraj
Could you check if mwifiex is activated in the kernel config?
Hi @jaski.tx ,
I don’t see mwifiex under Boardcom but I found under Marvell and enabled. I don’t see any error while executing but no virtual adopter created in ifconfig.
I enabled below so far:
[*] Broadcom 43xx SDIO device support

Thank you

Actually as we already found out, you have a dongle with broadcom wifi chip.
So you should look for a module containing bcm in the name. ( find / . -name bcm* ).
Once you find the module (.ko file), then you try to load it.
Best regards,
Jaski

Now we have Laird WiFi module Marvell 88W8997 chipset.

I do not see wlan0 or something to config IP address?
is there anything I am missing?
Thank you

Hi @jaski.tx ,
Could you please help me on this? I posted here as it is more relevant on this thread.
Thank you
Neeraj
Sure, Thank you.
You are welcome.
