CAN communication is done using the socket CAN driver taken from the mainline kernel. This means you are not using a mainline kernel, right? Are you using Freescale's ltib linux-2.6.35 tree? > Issue - Data transfer not happening at 1Mbps bitrate , works fine on other bitrates. > > Please help in resolving the issue. - From what kernel version is the Flexcan driver derived? - What does "dmesg" report when you load the driver? - What does "ip -d -s link show can0" report after an unsuccessful transfer? - What does "candump -e any,0:0,#FFFFFFFF" report while sending messages?
