Hi,
I try to receive data from CAN network. I got a PCI card with a FPGA

Hi all,
my platform is a mpc5200b based one. I wrote
some rtdm driver for that platform on linux-2.6.18
kernel. Some info:
- ARCH=ppc
- no fdt (so no dts)
- u-boot
- xenomai 2.3.2,
- adeos-ipipe-2.6.18-ppc-1.5-01.patch
All works fine.
Now i want to use:

Wolfgang,
You are right. I am just learning the sja1000 registers and modes and I was
looking at the 'BasicCAN' register configuration and the sja1000 can driver
is using the 'PeliCAN' mode. So it does look like everything is configured
correctly and it also looks

Thank you for the help. I do have XENO_DRIVERS_CAN_DEBUG enabled and the

I agree that rtcan1 transmit interrupt request is set as is rtcan0 receive

I am testing CAN using a TS_CAN1 PC-104 card on an x86 Nano-7240. It appears
that none of the existing SJA1000 drivers support this hardware so I created

Hello,
I understood that GDB can be used to debug Xenomai real-time
applications but it seems not to work with my application on PowerPC or
ARM. The applications looses determinism quickly, mainly because RT
threads switch to secondary mode somehow. Have I missed something? Are
there any known
