Tinycore 14.0 64bit: Macbook Air Wifi - Broadcom 4360 WLAN - wl not found

[pek]

Hi all.. I'm back again with more questions 

This time, I loaded these to my initial failed attempts to make wifi on a macbook air working.
dbus.tcz
firmware-broadcom_bcm43xx.tcz
wifi.tcz

When i typed iwconfig, no wlan adapter was found.

This is what i get in dmesg that i think related to it

Code: [Select]

[   16.037321] i801_smbus 0000:00:1f.3: SMBus using PCI interrupt

[   16.160895] b43: probe of bcma0:1 failed with error -95
[   16.160918] Broadcom 43xx driver loaded [ Features: PNLS ]
So, I could't make the wifi work.


Then I tried other distro which also failed.
After some random google searching, I found a suggestion that makes wifi works on other distro. By doing this

Code: [Select]

$  modprobe -r b43
$  modprobe -r bcma
$  modprobe -r wl
$  modprobe wl


When I tried to replicate this with Corepure64, I'm stuck at

Code: [Select]

$  sudo modprobe wlIt says wl not found in modules.dep

Here's the lsmod

What should I do from here?
Thank you.

The first thing to check with lsusb or lspci is what hardware you have.

The last time I compiled wl it literally needed 10 patches..

Hi Juanito,

The first thing to check with lsusb or lspci is what hardware you have.

Actually I loaded all available firmwares/drivers for wifi from Tinycore64 repo.
And when i dmesg, it found this Broadcom 4360
So, I guessed this was correct.

I will run lspci later again though, to do it proper way and educate myself.
I don't think it's related to lsusb, because it's a built in wifi module. But I will also run lsblk out of curiosity.
I'll post back after I get more details of these.

The last time I compiled wl it literally needed 10 patches..

I hope this is not about kernel compiling again
I'm still far out of league about that for now.

[Juanito]

Apparently there are two versions of the 4360:

14E4:4360 no linux driver
14E4:43A0 wl driver

Use “lspci -vnn | grep -i net” to find which you have.

[pek]

lspci -vnn | grep -i net gave me

Code: [Select]

03:00.0 Network controller [0280]: Broadcom Limited BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)
so, it's wl then.. 

So, do i have to recompile kernel for this?
or
Is there a way to make a tcz for this? (I prefer this if possible though)

And.. btw

14E4:4360 no linux driver
14E4:43A0 wl driver

How did you figured out one is "no linux driver" and the other is "wl" just by looking at those numbers?

[Juanito]

Is there a way to make a tcz for this?

I'll take a look, however it looks like broadcom have not updated the source since this: http://tinycorelinux.net/11.x/x86_64/tcz/wl-modules-5.4.3-tinycore64.tcz.info

It was the first hit on google...

Here some more clues, you should blacklist lots of modules.

https://bbs.archlinux.org/viewtopic.php?id=249038

And here they using the Linux Technic "DKMS".

I don't know so much about how to accomplish that in TC.

[Juanito]

The modules to blacklist are in the wl info file above and there is a blacklist boot code.

Thank you so much for this. No rush though. Anytime convenient to you. Thanks.

I searched high and low for "14E4:4360" trying to find a "no linux driver" as a literal driver, with no avail and finally I think what you meant was
- There's no linux driver for this 14E4:4360
as opposite to what i thought was
- There's a linux driver named "14E4:4360 no linux driver" 
Well.. now i learn many advance things and also to understand simple statement

Hi everyone,
after completing a task of compiling kernel and creating module with massive helps... here:
http://forum.tinycorelinux.net/index.php/topic,26244.30.html

I'm tempted to try to create this "wl" module.

Before I start, there are few questions.. as usual
1. Can I reuse the source that I already "ticked" (SPIxx.. etc) or should I create a fresh "make menuconfig"?
2. This is the screenshot when I tried to reuse. Do I just tick everything related to Broadcom?

and then "make"
3. I hope it's that simple.. But I highly doubt that 

[Juanito]

The wl module is not in the kernel source - you need to download its source code from the Broadcom site. The link is in the wl info file in the 11.x repo.

Note that the latest debian build uses 27 patches.

..seems the source has moved to here: https://docs.broadcom.com/docs/12358410

Thanks for the update.
I downloaded from https://docs.broadcom.com/docs-and-downloads/docs/linux_sta/hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz
as mentioned in http://www.tinycorelinux.net/11.x/x86_64/tcz/src/wl/. And I think they are the same.


This part.. I'm lost:

Code: [Select]

patch -Np1 -i ../wl-licence.patch
patch -Np1 -i ../wl-linux.c.patch
...

make API=CFG80211 -C /usr/src/linux-5.4.3 M=`pwd`there are no such files..??

[Juanito]

You’ll need to look back in previous repos for the missing patch files i.e. 10.x, 9.x, etc.

Substitute the actual location of your prepared source for /usr/src/linux-5.4.3

[Rich]

Hi Juanito
I copied all of the patches to:
http://tinycorelinux.net/11.x/x86_64/tcz/src/wl/

I'll do the same for x86.
