I'm developing software for the Freescale P1010 microcontroller, running:
Linux buildroot 2.6.35.13 #30 Mon Jun 20 10:49:21 CDT 2011 ppc
GNU/Linux
It has two FlexCAN CAN 2.0B interfaces which are configured as:
ip link set can0 up type can bitrate 1000000
ip link set can1 up type can bitrate 1000000
I've got two apps running that utilize SocketCAN to access the CAN
device, both open the same interface (can0). App B is listening for a
packet with a specific ID/mask. App A starts and sends a packet with
the appropriate ID that B should catch, but B never sees it. If I start
App B on the second CAN interface, it does see the pack (as expected).
I have queried CAN_RAW_LOOPBACK via getsockopt() and it says it is a 1.
Also if I create a vcan interface, and both A and B open that interface,
all works as expected.
What might need to do to get the Flexcan interface to behave the same as
the virtual can interface?
Thanks!
