I was told that Bosch's page for the C_CAN is here: http://www.semiconductors.bosch.de/en/ipmodules/can/canipmodules/c_can/c_can.asp There it's also written for what bus interfaces the C_CAN is available for, e.g.: "The ASIC version is delivered with the AMBA APB bus interface from ARM."On ARM we also have the AMBA bus abstraction in Linux, but I've never worked with it. IIRC Wolfram (Cc'ed) has recently touched it.
For a programmer, it feels very much like a platform-bus (you can even use amba-devices on a platform_bus); it has the advantage of some identification registers at the end of the address-space. The rest is more about how to connect the core to the SoC. Does that help? I don't know what the actual question is :) Regards, Wolfram -- Pengutronix e.K. | Wolfram Sang | Industrial Linux Solutions | http://www.pengutronix.de/ |
