I have ported the HiCOCAN driver from linux to qnx6.4. The driver can succesfully send and receive the CAN packets on both the channel. But the driver works at 1% bus load only. It’s not working at the higher bus load. Does anyone knows that why the driver is not working at higher bus load, what could be the possiable reason and how to fix this problem?.
Seems like you didn’t get it. It’s impossible for anyone to give you any clue as to what is going on with so little details. The number of possible reasons for such an problem are astronomous.
That being said you might use the debugger and/or system profiler to get an idea of what is going on.
