PEAK-Linux Driver on Raspberry Pi

[Hans.Peter]

Yes, i've the same problem like Chris. Installed today latest raspbian with all updates and 3.6.11+ kernel-headers from github.com

My output:

O.k. here i tried the 7.9 driver. But with 7.8 i've the same module insert problem. Only difference with 7.8: No "malloc_sizes" warning.

Hi,

Is it possible to copy-paste the output of dmesg, when the module insertion failed, please? When a module failed to load, we get a bit more information from the Kernel logs.

$ dmesg | tail -n 20

should do the trick.

Thanks and regards,

Stéphane

Here the output of installing the kernel headers. Maybe it's usefull too. Please attend to the grep error that will occur.

Hi,

"pcan: disagrees about version of symbol module_layout" tells that there is a problem between the Kernel you're running and the headers you are using to build pcan.

Could you upload the "pcan.ko" please?

Regards,

Stéphane

[Hans.Peter]

Here my pcan.ko

[S.Grosjean]

Hi,

I need now the following 2 files please:

1 - type

$ zcat /proc/config.gz > /tmp/running.config

then upload resulting "/tmp/running.config".

2 - upload "/usr/src/linux-headers-3.6.11+/.config" too

Regards,

Stéphane

[Hans.Peter]

Here the kernel config files

[S.Grosjean]

Hi,

It looks like you didn't do the "make install" command after you built "pcan.ko".

You may have a look to this post (http://www.peak-system.com/forum/viewto ... t=10#p2015) for a successfull install.

First try to with 7.8 (no malloc_sizes undefined symbol odd warning)

Best regards,

Stéphane

[Hans.Peter]

It looks like you didn't do the "make install" command after you built "pcan.ko".

No i don't. But if i execute 'make install' the pcan.ko module will be installed to '/lib/modules/3.6.11/misc/'
As 'uname -r' shows me '3.6.11+' i think '/lib/modules/3.6.11+/misc/' should be correkt. I've created
misc dir manually and copied the module in the directory and still get

I solved it for me now by switching from the Rasperry Pi foundation kernel to the one from Raspbian themselves. This has the added bonus of this kernel having socketcan enabled. I strongly believe that the kernel headers mentioned in the instructions don't match anymore with the kernel that is currently included in the Raspberry Pi foundation's latest "Wheezy" image.

I did a lot of things so I don't know if the following is complete, but it should take one pretty far. First, one should install the 'dkms' package, kernel image and headers:

Code: Select all

sudo apt-get install dkms linux-image-3.6-trunk-rpi linux-headers-3.6-trunk-all

This takes a while. Then, add the following lines to /boot/config.txt in order to boot with the new kernel:

Code: Select all

kernel=vmlinuz-3.6-trunk-rpi
initramfs initrd.img-3.6-trunk-rpi followkernel

Then reboot, and rebuild the driver as mentioned in the instructions. Optionally, build it with netdev support.
