I'm trying to run the flexcan example of MQX 4.1 for PXN20 on our custom board which has a MPC5668G (automotive version). I've only modified the clock setting of the BSP (InitClock function), the BSP_XOSC_CLOCK and BSP_FMPLL0_CLOCK constant to fit our board.
In the example, I've only modify the bitrate, the CAN_DEVICE (I use Flexcan B) and the CAN clock (I use FLEXCAN_OSC_CLK).
The transmission works fine which tells me that the connection between my PC and the board is not the problem. I can also see that the message I send from my PC is received in the message buffer when I check the registers. The only thing is that the ISR is not called.
Is there something I'm missing here? Is there a configuration to set in user_config.h to enable the interrupt (MQX_USE_INTERRUPT is already set) ?
