Compiler/TCAN4550EVM: CAN FD data length problem on TCAN4550EVM

Tool/software: TI C/C++ Compiler

Hi,

I am using TCAN4550EVM to receive CAN FD data.
The input data length is 64 bytes with 1M CAN speed.
However, the DLC contained in header only shows 15 bytes.

Is there a data length limitation?

Is following settings correct for 1M CAN speed transmission?

/* Configure the CAN bus speeds */
TCAN4x5x_MCAN_Nominal_Timing_Simple TCANNomTiming = {0}; // 500k arbitration with a 40 MHz crystal ((40E6 / 2) / (32 + 8) = 500E3)

TCANNomTiming.NominalBitRatePrescaler = 1;
TCANNomTiming.NominalTqBeforeSamplePoint = 32;
TCANNomTiming.NominalTqAfterSamplePoint = 8;

Regards,
Ethan
