add pcan-linux to yocto-based distribution

Post by Vincent Daanen » Mon 9. Apr 2018, 15:14

Hi,

I'm building an embedded system which uses a mcpie-to-can board.
The motherboard is a Intel J1900 based mother board (so x86_64 processor type).

I added a recipe to my layer but build of "peak-linux-driver-8.5.1.tar.gz" failed.
The first time, it failed because the popt.h file was not found.
I followed the advice given in this thread .. That's the reason of the do_compile function.
(see below)

Now, when compiling with this recipe, the process fails with the following error: implicit declaration of function 'pci_enable_msi_range'; did you mean 'pci_enable_msix_range'?
Moreover, it seems that the makefile will create a cross-compiled module because it assumes that the system running the makefile is the target system.

So is the a work-in-progress which aims at making makefiles of the archive compliant with Yocto?
If not, can someone help me to fix the compilation error reported just above?

Thanks

Vincent

Ps: sorry for the long post..

Hi,

which CAN hardware from PEAK do you want to use on your system?

regards

Michael

Hi,

this one with one channel
(i.e. PCAN-miniPCIe Single Channel IPEH-003048)

Re: add pcan-linux to yocto-based distribution

Hi,
just to give indications for people who may run into same trouble: I found a yocto layer which provides a recipe to add pcan to the image.
I could use it but at the moment, no pcan driver exists in the image...

Re: add pcan-linux to yocto-based distribution

Hello,

Strange compilation error that should not exist since pci_enable_msi_range() is used by the pcan driver only for Kernels in range [3.14 .. 4.10[, while the logs of the "make" command says it compiles the driver with the headers of Kernel v4.13.x...

Do you confirm that the version of the Kernel that runs in your embedded system is 4.13.x?

Up to now, we didn't cross-compile pcan with Yocto but with several other embedded cross-compilation environments. Generally speaking, and according to the User Guide, cross-compiling pcan should be made like this:
  • Specifying KERNEL_LOCATION to the Kernel headers of the target Kernel
  • Defining the global CC variable to the cross-compiler of the target arch
According to your make logs, I think CC is ok. But what about KERNEL_LOCATION? Could you change KERNEL_SRC into KERNEL_LOCATION in your make cmd line? If not, you might try replacing all occurrences of "KERNEL_LOCATION" by "KERNEl_SRC"in pcan/driver/Makefile.

Note that this last proposal is ONLY a temporary workaround, to first try to fix where your own problem is located.

Regards,

Stéphane
