Hi, i have a problem with the performance of the FlexCan on MarsBoard. Reading at a bitrate 1000000 leads to a loss of about 3% of the packets when the CAN bus is loaded to 18%.

I use Linux kernel version 3.0.15, standart flexcan driver and libraries from this source All Boards FlexCAN. FIFO buffers enabled by default.

I want to know: this is normal for this controller? I ask the Board to improve the performance for normal operation with bus load at least 60%.
