Some time ago, I debugged the mcp2515 driver in Linux. The driver basically passed the debugging. Some problems occurred when I debugged several other boards in the past two days.   1. When Linux is started, probe mcp2515 sometimes fails, sometimes

1. Overview/what is Socket can--------------------------------the Socketcan package is an implementation of can protocol S (Controller area Network) for Linux. can is a networking technology which have widespread use of automation, embedded devices, and automotive fields. while There has been other can implementations for Linux based on character devices, Socket CAN uses the Berkeley s Ocket API, the Linux network stack and implements the CAN device d
