Error controller problems. PCI module

[cpaniagua]

Hello,

I'm using a PEAK-pci module to send data from my PC to another. I installed the last drivers (8.7) without problems. My PC recognizes the pci module but the problem comes when I try to send data through a socket can. I get the following error:

error.png (225.77 KiB) Viewed 2359 times

I compiled with NET=NETDEV_SUPPORT.

Could anybody help me?
Thanks in advance!

Hello,

We actually can't guess how the error frames are displayed by your software. Could you please explain what are the fields that are part of the [WARN] lines?

AFAIK these are CAN error frames (0x20000000). But you might understand that we can't guess what are the hexadecimal digits next to the # (id? dlc? data? in which order?)

Please redo "cat /proc/pcan" after the problem has occurred. Having last Status column value could also help us in the diagnostic.

Please do also "ip -s -d link show can0" to know the status of the interface seen by linux-can.

Finally, do also "dmesg | grep pcan" as well as "uname -a" please.

Regards,
