Hi,

some months ago [1] were posted that with the 8.5 version it could be used with Xenomai 3. I have checked 8.5.1, and it doesn't build with make xeno3.

Any progress on this topic?

Ok, perfect. I can test.

I'm preparing also the debian package.

Any new about this issue? (support of Xenomai 3.X)

Hi,

It looks like you're always receiving these CAN messages every 3 ms from the bus:

id=979 len=8
id=980 len=8
id=981 len=8
id=982 len=8

Could you first check if it's normal.



Yes, it's normal. We try to make some control.



Next, with such a high frequency of reception, you could try to ...

Done!!!!

Hello,

Generally speaking, the -28 error occurs when the Rx FIFO of the driver receiving messages from the hardware is full.

Hi,

do you use any USB hubs or extension cables in your setup? What kind of CAN hardware/CAN cables do you use on your CAN system, and which baudrate do you use? (pcan32 uses 1Mbit/s while pcan33 is on 500k)

I don't use any USB hub or extension cable.

I have used again the peak-usb device and then:

I have tested it too in

with the same result.

just an clarification. I'm not using the Xenomai driver. Just the standard Linux driver. In any case, I have tested it with another kernels (non-RT) and it fails in the same way.
