I have a CAN stack project integrated with CanNM.(S12G128 with Trace32 debugger)
And I add CAN DisInterrupt/EnInterrupt in exclusive area like this:
, RTE_CODE) SchM_Enter_CanNm_SCHM_CANNM_EXCLUSIVE_AREA_0 (
/* disable */
CAN_RIER = 0U;
CAN_TIER = 0U;
/* FUNC(void, RTE_CODE) SchM_Enter_Nm_SCHM_NM_EXCLUSIVE_AREA_0 (void) */
, RTE_CODE) SchM_Exit_CanNm_SCHM_CANNM_EXCLUSIVE_AREA_0 (
/* enable */
#if (CAN_RX_MODE == CAN_INTERRUPT_MODE)
/* The CAN interrupts defines have been specified to correspond with */
/* the CANRIER and CANTIER registers */
/* CANRIER : 7 : WAKE-UP */
/* 6 : CAN status change */
/* 5..4 : Rx status change */
/* 3..2 : Tx status change */
/* 1 : Overrun */
/* 0 : RxOK */
/* CANTIER : 7..3 : unused */
/* 2 : TxOK mailbox 2 */
/* 1 : TxOK mailbox 1 */
/* 0 : TxOK mailbox 0 */
CAN_RIER |= CAN_RIER_RXFIE;
/* TxOK interrupts are enabled before each frame transmission. */
/* They must be disabled if any frame transmission is in progress */
/* to prevent from a TxOK interrupt which is not due to a frame transmission */
CAN_TIER = 0U;
/* Generate CSCIF interrupt in Bus-off state both in interrupt and polling mode */
CAN_RIER |= CAN_RIER_TSTATE_BOF;
#if (CAN_ERROR_STATUS_MODE == CAN_INTERRUPT_MODE)
/* Generate an error interrupt request when CSCIF bit is set */
CAN_RIER |= CAN_RIER_CSCIE;
/* FUNC(void, RTE_CODE) SchM_Exit_Nm_SCHM_NM_EXCLUSIVE_AREA_0 (void) */
But when I run this program, it will not working normally.
It should send period frames but only send several times and stop sending.
Program is still running, not fleeting.
I referred to S12XHY128 and S12G192, but I didn't find breakpoint.
Does anyone have suggestions about this?
