Install failing with "invalid module format".

Hi Andy,
You might want to log in and change your username as using your email address in forums might get you some additional spam.
We'll have a look now and see if we can build the latest version and if we can get source and pointers etc., we'll throw it on the web.

Hi Andy,

Sorry about the delay, hopefully this will explain things better.

The "Invalid module format" error is Linux jargon for your driver was not built for the specific kernel version you are running, the system is basically preventing the driver from being loaded since it cannot be sure it is compatible, and an incompatible driver can cause problems.

The best solution is to build the driver for the correct kernel version (the checks can be ignored but it may cause problems).

The first thing you will need to build is to have the kernel headers to build the driver with.
The following lines will download and run a script which attempts to download the latest kernel source (hopefully the same version as your copy).

cd ~
wget -O get-kernel-source.sh http://piborg.org/downloads/get-kernel-source.txt
chmod +x get-kernel-source.sh
sudo ./get-kernel-source.sh

You can view the script here.

Assuming that was successful then you will need to download the source for LedBorg.

mkdir ~/ledborg-source
cd ~/ledborg-source
wget -O source.zip http://www.piborg.org/downloads/ledborg/source-rev2.zip
unzip source.zip

Finally we need to build the driver code and install the files (we will use the pre-build GUI).

cd ~/ledborg-source/driver
make
cd ..
cp gui/ledborg_gui ./
chmod +x install.sh
./install.sh

If you really do not want to build the driver yourself I have uploaded the version I just built to test the above instructions, it can be installed using

mkdir ~/ledborg-setup
cd ~/ledborg-setup
wget -O setup.zip http://www.piborg.org/downloads/ledborg/raspbian-3.6.11-rev2.zip
unzip setup.zip
chmod +x install.sh
./install.sh

For reference my system returns the following for uname -a.
Linux raspberrypi 3.6.11+ #371 PREEMPT Thu Feb 7 16:31:35 GMT 2013 armv61 GNU/Linux

Hi all,
i hane a 512mb revB board, same problem outthebox, tried same solution before in this post without success.

Plase can someone help me? Maybe i need to "clean" some configuration because i make several test but i don't know how.

problem:
Installing LedBorg, please wait...
Error: Module ledborg is not currently loaded
update-rc.d: using dependency based boot sequencing
Error: could not insert module /home/pi/ledborg.ko: Invalid module format
LedBorg installed, LedBorg should now be green
(led is always off, never see it up)

Edit: Log of build attached

Hi,
i can't check for some days, sorry. I think (not sure) to have installed Debian Wheezy Raspbian.
I'm sure have installed it with BerryBoot. Maybe this is the problem ?
Sorry can't check better because not in office now (and in office have not a tv or hdmi display) so excuse me, but i'm sure for berryboot; i don't know if berryboot manage custom kernel.

tomorrow i'll be in office, i'll check and report exact operating system but i'm pretty sure of Barryboot.

bye

I confirm installed is Barryboot, inside Wheezy Raspbian 2012.12 fully updated. Maybe barryboot this is problem. I need remove it?
Thanks

OK, made a new install with raspbian without berryboot; update all and installed ledborg sw.
WORK LIKE A CHARM ! so problem is something related with berryboot.
Not a problem for me but hope my experiance maybe useful for any one.

Thanks for that. My LedBorg works just like it did before I did a dist-upgrade.

:)

It is always a let down when you get a invalid module format notice. That is something that would upset me if I was to get. I am just glad that there are ways around them and can really help you out.
