Regarding the CAN issue of s32k344

The compiler I am currently using is s32ds3.4, RTD2.0.0. Among them, CAN FD function is enabled for can0-can5, and ENABLE RX FIFO function is enabled for can0. The implemented function is that can1 sends 64bit data to can0, can4 sends 64bit data to can2, and can3 sends 64bit data to can5. However, why can can0 and can5 receive data normally but can2 cannot receive data? When I set can4 to Loop-back mode, can4 can also receive data normally. The hardware connection is achieved by connecting CANH of can1 to CANH of can0, CANL of can1 to CANL of can0, CANH of can4 to CANH of can2, CANL of can4 to CANL of can2, CANH of can5 to CANH of can3, and CANL of can5 to CANL of can3 using DuPont wires. Here is my code
