Hi all,
I have some problems about the CAN transmited.
I am using CANoe to transmit CAN message with our own designed board, but the CAN module keeping going to ISR.
{
FLEXCAN_Error_IRQHandler(2U);
}
also the register ESR1 = 0x242252
and CANoe responsed message
System 821.950000: CAN 1 : Message with ID = 1 could not be sent. Driver error 11 in TransmitCANFrame
The CAN message keeping non-ACK and retry again and again
If I power-on then power-off the board and the CANoe keeping starting, and the issue stiil exists. How can I fix this issue?

Hi Selent,
I'm using the SDK 4.0.3, S32DS Ver 3.4, and below is the flexcan setting.
#include "canCom0.h"
flexcan_state_t canCom0_State;
const flexcan_user_config_t canCom0_InitConfig0 = {
.fd_enable = false,
.pe_clock = FLEXCAN_CLK_SOURCE_PERIPH,
.max_num_mb = 32,
.num_id_filters = FLEXCAN_RX_FIFO_ID_FILTERS_8,
.is_rx_fifo_needed = false,
.flexcanMode = FLEXCAN_NORMAL_MODE,
.payload = FLEXCAN_PAYLOAD_SIZE_8,
.bitrate = {
.propSeg = 7,
.phaseSeg1 = 4,
.phaseSeg2 = 1,
.preDivider = 13,
.rJumpwidth = 1
},
.bitrate_cbt = {
.propSeg = 7,
.phaseSeg1 = 4,
.phaseSeg2 = 1,
.preDivider = 13,
.rJumpwidth = 1
},
.transfer_type = FLEXCAN_RXFIFO_USING_INTERRUPTS,
.rxFifoDMAChannel = 0U
};
I am using CANoe to feed the CAN meassge, and the CAN messages responsed NACK. Once the CAN message was not sent success, so kept re-sending CAN message per 50us.
If I want to make the flexcan module worked normally again, what's the setting should be changed.
