Questions about receiving various CAN Msgs

Hello

 

We are considering using multiple MAILBOXs to handle the received Multi CAN Msg.
However, the test result shows that MAILBOX (0,1) with maximum 2ea including Tx/Rx can be used and 'STATUS_CAN_BUFF_OUT_OF_RANGE' is generated when using more than this.
ex)
#define RX_BUFF_IDX 0U, #define TX_BUFF_IDX 1U - ok
#define RX_BUFF_IDX 0U, #define RX_BUFF_IDX_2 1U - ok
#define RX_BUFF_IDX 0U, #define RX_BUFF_IDX_2 1U, #define RX_BUFF_IDX_3 2U - fail

 

How can I receive various CAN Msgs?
I was refer to example code of can_pal_s32k144

 

Thanks
