Then there is a problem with the interrupt signal from the MCPx chip back to the driver. Which indicates GPIO is configure as an in put, currently has a hi gh logic level, is mapped to IRQlinuc causes an interrupt on the falling edge. You may find some clues at the following link.
CAN bus Linux driver – ArmadeusWiki
I know from experience Up to four boards could be placed in one computer. The driver implements something like a virtual CAN network, where producer and consumer exchange CAN frames only virtually. At least, a proper GCC installation is needed, and ncurses development package are used by kernel menuconfig. My can controller is mcp, SOC is s3c, and based on linux kernel version is 2.
Refer to the Raspberry Pi forum, for latest discussions on this point: MCP chips are not ideal for high busload applications.
At the time of writing, the current kernel trunk version is 3. Then edit the board definition, to add the informations about the SPI bus, and to configure the interrupt pin of the MCP Pages with syntax highlighting errors RaspberryPi. Allow pass IRQ flags through platform Forum Themes Elegant Mobile. The titles of the following sections are text that gets displayed when a problem occurs. Then the CAN bus support must be added using “menuconfig” see.
So first create it, and then checkout the last version of the kernel for the raspberrypi in the linux subdirectory.
