Freescale has written the driver, ask them. The mainline flexcan driver uses the RX fifo feature of the new flexcan cores, which is AFAIC not supported on the coldfire, and I think the FIFO has a depth of 8 buffers. The mainline driver uses just currently just one buffer for TX. cheers, 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 |
