Hi all,
did anybody get the Flexcan running with 125 kbit and and has anybody the
correct bittiming?
i tried to transfer the Flexcan example from Freescale but icant get it
running.
Thansk in advance Yves

This bit timing and init works fine on my 60 MHz clk 56f8345.
FCMCR = FCMCR_9_SOFT_RESET;
FCCTL0 = FCCTL0_2_TO_0_PROPAGATION_SEGMENT_TIME_4_TQ;
FCCTL1 = FCCTL1_15_TO_8_PRESCALER_DIVIDE_FACTOR_30 |
FCCTL1_7_TO_6_RESYNCHRONIZATION_JUMP_WIDTH_1_TQ |
FCCTL1_5_TO_3_PHASE_SEGMENT_1_TIME_4_TQ |
FCCTL1_2_TO_0_PHASE_SEGMENT_2_TIME_7_TQ;
FCMCR ClearBit FCMCR_12_NORMAL_OPERATION_DISABLE_HALT_ENABLE;
FCMCR ClearBit FCMCR_14_DEBUG_MODE_FREEZE_ENABLE;
etc.
M.T.
