Building kmod-brcm-wl for -a supposedly- lantiq xrx200 SOC

For Developers
1

Hi!

I've been reading about the broadcom wl module and I've found that it's only available for the BCM47xx platform, so far.

BUT!

I've got a router which has (at least to my knowledge) the lantiq xrx200 processor¹.

...and it was running a version of broadcom-wl when it was on stock firmware (from which i've got a backup). And which btw was based on Barrier Breaker (as noted in the opkg.conf file).

The router has a broadcom 43222 ² wireless card, which i cannot get to work either with b43, b43-legacy, nor brcmfmac or brcmsmac.

it reports the following to lspci:
00:0e.0 Network controller: Broadcom Inc. and subsidiaries Device a8d6

When I try to use bcm47xx's module on my router it responds:

root@OpenWRT:~# modprobe wl
invalid endianess: 1
failed to load the .modinfo section from /lib/modules/4.14.195/wl.ko
invalid endianess: 1
failed to load the .modinfo section from /lib/modules/4.14.195/wl_glue.ko

So. I've got many questions:

How to know precisely which SOC does it have?
is it possible that cat /proc/cpuinfo lies to me?
is it possible for cat /proc/cpuinfo to be biased?

Can I rebuild kmod-bcm-wl with the alternate 'endianess' (from le to BE, or all theway around) ?

How can I port the backed wl version of my router to the 4.14.195 kernel version in 19.7.4?
Is it possible to get the 4.195 kernel to use the older 2.6.32 module (which worked in stock firmware)?

² I know it's listed as 'NOT TESTED' in [linux wireless], but I've got the proof of concept of it working on previously.

Hi @tulainas ,
It definitely use lantiq VRX200 family SoC. Cpuinfo shows it's a ZyXEL P-2812HNU-F1, but this model has a Ralink radio. What exactly is the model written on the label?

Can you show the entire bootlog?

Hi, sure!

Here it is.

But I've got to say that I flashed it with openWRT's ZyXEL P-2812HNU-Fx firmware on purpose, since it was the most similar; hence my first three questions:

How to know precisely which SOC does it have?
is it possible that cat /proc/cpuinfo lies to me?
is it possible for cat /proc/cpuinfo to be biased?

I've tried to copile the module, from:
Broadcom's site

But I always end up with the same compilation error (at first I thought it was because of being using Arch, but it also fails on Ubuntu):
