PCAN-miniPCIe FD - IMX6 - kernel 4.9.124

Hi,

your cansend command looks ok. You can try to use "cangen can0" to generate random CAN frames on can0.

Please post the output of cat /proc/pcan again, to see if the write counter increases during your tests.

Hi Michael.

I have tested:

Code: Select all

Hi
For another test, I have unsoldered fields that i said before.
This consists on testing the same driver on X86 platform with ubuntu-16.04.5-desktop-i386.

In this case, the driver is working. i can see the signals in the osciloscope and connect the ports to comunicate them.
The procedure to test is:
1. rmmod peak_pciefd
2. insmod pcan.ko
3. ip link set can0 type can bitrate 100000 #(I tested this lower speed than 1000000)
4. ip link set can0 up
5. cansend can0 01a#12345678

I have done the same test in IMX6 platform, but i can see the signals when I run cansend.

NOTE: The driver is compiled "make pci_only"

Thank you.
Best regards.

Hi,

I have done the same test in IMX6 platform, but i can see the signals when I run cansend.

Hi.

No, it is not working on IMX6, only it is working on X86 paltform.

Best regards.

Hi,

in your last post you said it was working, maybe you miss the "not" in your statement (see the quote in my post)

please try to insmod the pcan driver with MSI on:

# insmod pcan.ko fdusemsi=1

Then retry your test please.

Hi.

Sorry Michael, it was my "not" mistake.

I have tested insmod pcan.ko fdusemsi=1, but it is the same, I can't see the signals.

Thank you.
Best regards

Hello,

Please, send us again the output of "cat /proc/pcan" (after insmod pcan.ko fdusemsi=1).

Thanks,

[pguillen]

Hi Michael

I have tried again the same test with insmod pcan.ko fdusemsi=1. I don't know what was happenig in the first test.
Now it is working !!! I am going to test all ports and combination of them.

Please, could you explain me the parameter and what it was happening ?


This is the output of : cat /proc/pcan
