Well, apart from the OCR setting, this document is not really useful. > I am going to read this.

No. If the chips is mapped correctly, it should work like with any other SJA1000 hardware. To be honest, I'm not even sure if this IXXAT card is supported properly by the sja1000_isa driver. I still think there is a problem with the irq setup or the ocr and cdr setting. Or it needs some special treatment. You could try contacting the IXXAT service. Maybe they can tell you more. Also, a CAN analyzer would be useful.
