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

Dear Petr Stancik

Thank you for quick response.
I increased the 'Number of buffers' as shown below but the problem was not resolved. (2->8)

We still return the same 'STATUS_CAN_BUFF_OUT_OF_RANGE' state when MAILBOX (0,1) with over 2ea including Tx/Rx be used.

Could you please guide to solving this problem.

Thanks
