Moin, the at91_can core has the following problem: "50.3.5.3 CAN: Contents of Mailbox 0 can be sent Even if Mailbox is Disabled"
This means under high bus load it can happen that the mailbox 0 is send to the bus. And it does happen, even with the mainline driver where Mailbox 0 is a receive mailbox. The errata proposes not to use mailbox 0 and load it with a unused can_id that will not disturb the bus. I'm going to implement the workaround. As the unused identifier is probably application specific my question is: What's the best way to configure this identifier? - sysfs - netlink - ioctl - ethtool - peek/poke :P What will be a good default can_id? regards, Marc -- Pengutronix e.K. | Marc Kleine-Budde | Industrial Linux Solutions | Phone: +49-231-2826-924 | Vertretung West/Dortmund | Fax: +49-5121-206917-5555 | Amtsgericht Hildesheim, HRA 2686 | http://www.pengutronix.de |
