The driver is provided by the producer of the card.It runs= well on regular linux.However, when I run it with preempt_rt linux ker= nel,although it's installed with no problem,the data of the can ports r= eceive always have some errors.It just can't rightly receive the datas = I transmit.Is it a driver problem?But I thought driver on preempt-rt li= nux should be the same with the regular one. If the driver has been written properly in terms of locking and API the= n there should be no problem after re-compiling. There is however a sja1000 driver in kernel, I suggest you try that one. > Looking forward to the reply.Thanks.
