Dear Sirs,I'm new to rt-socket-can and xenomai. I had a better look at the code of rtcan_rtt and found my mistake:What I really wanted to do was: first terminal: ./rtcan_rtt rtcan0 rtcan0 -c 250000 second terminal ./rtcan_rtt rtcan1 rtcan1 -r -c 250000
and now it works. Sorry and Best regardsEttore ----Messaggio originale---- Da: edibos...@inwind.it Data: 09/12/2011 14.52 A: <xenomai-help@gna.org> Ogg: [Xenomai-help] Interrupt issue on a PC/104 can interface? Dear Sirs,I'm working with an Ubuntu (10.04) system with Xenomai (2.5.6), with kernel 2.6.37.6 and with a Peak-System PC/104 can interface (isa), with two channels. I connected the two channels of the can interface with a cable (with the two 120Ohms resistor connected at each side) and did the following two tests: 1) ... rtcanconfig rtcan0 --baudrate=1000000 start rtcanconfig rtcan1 --baudrate=1000000 start then, in one terminal: rtcanrecv rtcan0 in another one: rtcansend rtcan1 0xA 0xB 0xC 0xD 0xE 0xF 0x01 0x02 Everything seems to work: I can see the message on the receiving terminal. I also tried changing rtcansend options, and it works as well. 2) Then I used the rtcan_rtt xenomai example program.In one terminal:./rtcan_rtt rtcan0 rtcan1 -r -c 250000 And in another one:./rtcan_rtt rtcan1 rtcan0 -c 250000 I also modified the rtcan_rtt to print some additional debug messages, and I found that for each can message sent from the transmitter channel I receive ~356 messages on the other channel, with lot of overruns and huge times. Maybee I have some problems with the interrupts?Note that with the rtcanrecv/rtcansend test, for each message sent with rtcansend, rtcanrecv receives one message. Thanks in advanceEttore
