Title: bcm-43xx firmware doesn't load
Post by: drtrppr on November 24, 2015, 06:04:47 PM: Hello,

Trying to get wifi working on TCE 6, but no success after some reading and trying.

System Stats - dmesg tab shows errors loading the bcm-43xx firmware, some files are missing? Incomplete tcz or do i have to download some other package?

b43-phy0: Broadcom 4318 WLAN found (core revision 9)

Add boot code blacklist=ssb,b43,bcma to your bootloader.
Add wl-modules-3.16.6-tinycore.tcz to OnBoot.

Add wl-modules-3.16.6-tinycore.tcz to OnBoot.

Did this, ended up with 'kernel driver in use: wl' (lspci), so driver loaded correctly. But, wl-driver doesn't support 4318, so wifi is not working.

Searching/reading says something about a cutter, found/installed b43-fwcutter, but that doesn't help either.

(Thought the loading error was a result of installing the broadcom_b43xx.tcz, but that's apparently not the case. When not loading the tcz, the error message is still present.)

From your log...

Code: [Select]
b43-phy0 ERROR: Firmware file "b43/ucode5.fw" request failed (err=-12)
You would need "firmware-openfwwf.tcz" (see attached pic), which has "ucode5.fw".

I hope this helps.

That would have been the first thing to do, see if requested file is on the system :-[ .

But, downloading the tcz didn't get rid of error. I can find the file in /usr/local/lib/firmware/b43, according to info I've read this seems the right place.

You need to load the firmware before loading wireless-KERNEL (which loads the b43 module).

Post by: drtrppr on November 30, 2015, 10:12:36 AM: Got a new bcm-43 firmware tcz, added a line to onboot.lst to load tcz, installed wifi.tcz, and all is working fine now.
