[SOLVED] rtl8192cu firmware problems

Hello community,

My bananapi-r1 with beowolf is currently complaing about wifi firmware issues.

[   15.327210] rtl8192cu: Loading firmware rtlwifi/rtl8192cufw_TMSC.bin
[   15.329000] usb 2-1: firmware: failed to load rtlwifi/rtl8192cufw_TMSC.bin (-2)
[   15.345792] usb 2-1: Direct firmware load for rtlwifi/rtl8192cufw_TMSC.bin failed with error -2
[   15.346165] usb 2-1: firmware: failed to load rtlwifi/rtl8192cufw.bin (-2)
[   15.353159] usb 2-1: Direct firmware load for rtlwifi/rtl8192cufw.bin failed with error -2
[   15.353182] rtlwifi: Loading alternative firmware rtlwifi/rtl8192cufw.bin

First of all I would like to figure out which version the current firmware is.
Also I would like to know to which  package the firmware belongs to.

Usually this firmware should be part of the ' firmware-realtek' package, bur when I do a 'apt search for the package I get zero results for it.

Do I now need to compile a newer version of the firmware into my system ?

By using the 'make defconfig'  route ?

If yes, which version should I pick ?
Since the current kernel version is

Linux r1-devuan 4.19.0-17-armmp-lpae #1 SMP Debian 4.19.194-3 (2021-07-18) armv7l GNU/Linux

And the archive does not list a exact match for this patch version.

Thx for any responses.

Re: [SOLVED] rtl8192cu firmware problems

$ apt-file search rtl8192cufw_TMSC.bin
firmware-realtek: /lib/firmware/rtlwifi/rtl8192cufw_TMSC.bin
$

The firmware is already installed and loaded onto the card, as indicated in the last line of your posted output.

Re: [SOLVED] rtl8192cu firmware problems

hello user9898,

can you do a output of 'dmesg' to see if there are any problems loading the firmware on boot..?
also
a 'ls -l /lib/firmware' to see the firmware files you have..

does you have a initramfs?
if yes, maybe you need to update the initramfs( 'update-initramfs -u' )..

Best Regards,

Re: [SOLVED] rtl8192cu firmware problems

hello,

It seems that is ends loading it..

But you should have those files in '/lib/firmware', and from the listing you have done there, I don't see them there
find were they are..

find / -maxdepth 4 -name rtl8192cufw_TMSC.bin -o -name rtl8192cufw.bin

Probably in '/etc/firmware' ?

Have you installed the package 'firmware-realtek' ?
you will need 'non-free' in your '/etc/apt/sources.list'

apt-get update
apt-get install firmware-realtek

If nothing above solves it,
Sometimes the userpace helpers in devuan point to '/etc/firmware', so the symlink should work, but only if the above doesn't..
try to create a symbolic link in '/etc':

ln -s /lib/firmware /etc/firmware

Re: [SOLVED] rtl8192cu firmware problems

hi,
The ' / -maxdepth 4 -name rtl8192cufw_TMSC.bin -o -name rtl8192cufw.bin'
comes up with nothing.

And when I do a 'apt search' for the packag 'firmware-realtek' I also do get zero results back.

How should my 'sources list' look like

I changed to the following format.

# deb http://deb.devuan.org/merged beowulf main

deb http://deb.devuan.org/merged beowulf main contrib non-free
deb-src http://deb.devuan.org/merged beowulf main contrib non-free

deb http://deb.devuan.org/merged beowulf-security main contrib non-free
deb-src http://deb.devuan.org/merged beowulf-security main contrib non-free

# beowulf-updates, previously known as 'volatile'
deb http://deb.devuan.org/merged beowulf-updates main
deb-src http://deb.devuan.org/merged beowulf-updates main

Copying  the Debian format.
Hope that is correct.
But than I am also getting some strange error's when I am running a 'sudo apt update'

sudo apt update 
Holen:1 http://deb.devuan.org/merged beowulf InRelease [33,8 kB]
Holen:2 http://deb.devuan.org/merged beowulf-security InRelease [26,3 kB]
Holen:3 http://deb.devuan.org/merged beowulf-updates InRelease [26,7 kB]

Re: [SOLVED] rtl8192cu firmware problems

OH NO!!!
How could I miss that?!?
Yeah after installing ntp and ntpstat, the apt updates stopped complaining. And the 'apt search' also finally found the firmware-realtek package.

sudo dmesg | grep rtl
[sudo] Passwort für blub: 
[   14.608807] rtl8192cu: Chip version 0x11

Feeling like the idiot of the day here.aaarrghh!!!

Re: [SOLVED] rtl8192cu firmware problems

hello user9898,

Like yeti said above,
yeah, you need the date to be more or less updated to use apt..

Since you have installed 'ntp' package,
Any time that you loose the date( by any reason.. ), you can just update it, before using apt

ntpq -p

yeah your problem from the beginning was that you didn't had the 'firmware-realtek' package..
Don't worry,
The most important thing is that you already solved the problem
