Compilation error with PCAN-miniPCIe Single Channel

[aperlado]

Hello,
I'm a bit desperate with the driver of mi can board.
First of all I'm try to establish CAN communication between my PC (Linux Ubuntu 16.04) (kernel 4.13.0-45-generic) and another PC. For that I'm using a PCAN-miniPCIe Single Channel (https://www.peak-system.com/PCAN-miniPC ... html?&L=1#). I download the driver 8.5.1 from the official website (https://www.peak-system.com/fileadmin/m ... /index.htm) and follow all the steps in the documentation, but when I'm try to compile it I obtain two different errors, as you can see in the picture bellow. What i should do?

Hi,

The code with "pci_enable_msi_range()" shouldn't be compiled since everything looks like you're running Kernel 4.13:

src/pcan_pci.c; line 278:

Code: Select all

#if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 10, 0)
#define pcan_pci_enable_msi_range(a, b, c)      \
        pci_alloc_irq_vectors_affinity(a, b, c, PCI_IRQ_MSI, NULL)

#elif LINUX_VERSION_CODE >= KERNEL_VERSION(3, 14, 0)
#define pcan_pci_enable_msi_range(a, b, c)      pci_enable_msi_range(a, b, c)

#else

Can you give us the output of:

Code: Select all

$ uname -a

About your 2nd issue: the enclosed Documentation says that you have to install the libpopt-dev package to be able to successfully compile the test programs:

Code: Select all

$ sudo apt-get install libpopt-dev

Now the second issue its fixed, I don't obtain the error of the popt.h.
The output of "uname -a" is: Linux Carretilla-MXE210 4.13.0-45-generic #50~16.04.1-Ubuntu SMP Wed May 30 11:18:27 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
And don't understand what i should do with the code of "pci_enable_msi_range()", should i remove it?
Thanks for the support.

Hi,

Please edit "driver/src/pcan_pci.c" and change line ~278:

Code: Select all

#if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 10, 0)

into:

Code: Select all

#if 1//LINUX_VERSION_CODE >= KERNEL_VERSION(4, 10, 0)

then save and rebuild the driver with:

Code: Select all

$ make -C driver

Tell us what happens please...

Regards,

Stéphane

Hi,
I modified the code as you explained to me, for compile it later with "make -C driver". I obtain the next lines, it seems that now its working fine.

[S.Grosjean]

Hi,

Yes it should. But I don't explain why you have had to do this change: according to your system configuration, your Kernel is 4.13, so the piece of code I told you to change should have been compiled by the compiler...

Tell us now if everything works.

Regards,

Stéphane

Hi,
I still have issues with the communication. My problem now is the next:
First of all I'm using socketcan_bridge to establish the communication, so when I write "ls /dev" to see what devices I can use, I see this:

. So i know I can use pcan0 and pcan1, but when I type "sudo ip link set pcan0 up type can bitrate 500000" I obtain the message: "Cannot find device "pcan0"". the same with pcan1.
I dont kwon how test if I configure the driver properly but, I compile it with "make PCC=NO DNG=NO ISA=NO USB=NO PAR=NO" and installed it with: "sudo make install".

[M.Maidhof]

please try:

ip link ls

and check which devices you see. Typically they are named can0, can1....

regards

Michael

Hello,

First of all I'm using socketcan_bridge to establish the communication, so when I write "ls /dev" to see what devices I can use, I see this:

Well if you plan to use "socket-CAN" then you certainly should build the driver with the NET option too:

Code: Select all

$ cd driver
$ make NET=NETDEV_SUPPORT ...
$ sudo make install

Then, you won't see any /dev/pcan* device node anymore but "canX" network interfaces instead.
Then, you'll be able to configrue them with "ip link" tool...

Hi,
I follow your indications, and i obtain new error messages, in this case the error codes are the ones you can see in the next picture:
