NXP wrote that= I'm not allowed to give away these documents, but I got them simply by asking N= XP on their website, so I suppose anyone can get them too. AFAIK the LPC1765 never had any CAN related errata reported. However I repo= rted an error in the documentation to NXP in January 2012 (CAN controller number= ing is wrong), they acknowledged the error but they never released an updated version of UM10360.pdf. So maybe there are other reported problems that don= 't make it to an errata document. The NXP test document I have is dated September 2006 and includes bus off testing. I can't test on the LPC1765 before next week at the earliest and the driver= I use is different because of the LPC1765 "pending interrupt problem", but wh= at you describe should appear here also if we have the same CAN cell. Can you describe what you do on the CAN bus to reach bus off? I could try to reproduce here and see if I also see RM staying at zero. Did you check the value of EWL? If is 0 or 255 I wonder what happens... --=20 You are receiving this mail because: You are on the CC list for the bug.
