We are working on S32K144 EVB Q0100 board with CAN transreceiver UGA1169
1. Clock source is BUS clock with 56Mhz frequency and sampling point chosen is 75%
2. Rx_Fifo = false
3. Fd_Enable = true
4. /* Macros to Configure Tx message buffer */
#define CANTX_DATALENGTH 64u
#define CANTX_FDENABLE 1u
#define CANTX_FDPADDING 0u
#define CANTX_ENABLEBRS 1u
The above mentioned values are passed in the function "FLEXCAN_DRV_ConfigTxMb"
/* Macros to Configure Rx message buffer */
#define CANRX_DATALENGTH 64u
#define CANRX_FDENABLE 1u
#define CANRX_FDPADDING 0u
#define CANRX_ENABLEBRS 1u
The above mentioned values are passed in the function "FLEXCAN_DRV_ConfigRxMb"
5. /* Macros for CAN_Baudrate setting for (CAN0->CBT with 500Kbps nominal bit rate) */
#define BAUDRATE_PROPSEG 54u
#define BAUDRATE_PHASESEG1 27u
#define BAUDRATE_PHASESEG2 27u
#define BAUDRATE_PREDIVIDER 0u
#define BAUDRATE_RJUMPWIDTH 27u
/* Macros for CAN_FD_Baudrate setting for (CAN0->FDCBT with 2Mbps higher bit rate)*/
#define BAUDRATE_PROPSEGFD 6u
#define BAUDRATE_PHASESEG1FD 13u
#define BAUDRATE_PHASESEG2FD 6u
#define BAUDRATE_PREDIVIDERFD 0u
#define BAUDRATE_RJUMPWIDTHFD 6u
Am not able to transmit or receive with the above mentioned frequency.
Are these values correct for the given frequency?
Is this a valid range of frequency for this transreceiver?
