We are testing UART of MPC5744P
we didn't get any error while using channel 1 " initLINFlexD_1"
but for initLINFlexD_0, we are getting IVOR1 error at Register 0x1001010.
It is stopping at
void initLINFlexD_0 ( unsigned int MegaHertz, unsigned int BaudRate ) {
unsigned int Fraction;
unsigned int Integer;
LINFlexD_0.LINCR1.B.INIT = 1; /* Enter Initialization Mode */ ///////////////STOPPING HERE//////////////////
LINFlexD_0.LINCR1.B.SLEEP = 0; /* Exit Sleep Mode */
LINFlexD_0.UARTCR.B.UART = 1; /* UART Enable- Req'd before UART config.*/
LINFlexD_0.UARTCR.R = 0x0033; /* UART Ena, 1 byte tx, no parity, 8 data*/
LINFlexD_0.UARTSR.B.SZF = 1; /* CHANGE THIS LINE Clear the Zero status bit */
LINFlexD_0.UARTSR.B.DRFRFE = 1; /* CHANGE THIS LINE Clear DRFRFE flag - W1C */
BaudRate = (MegaHertz * 1000000) / BaudRate;
Integer = BaudRate / 16;
Fraction = BaudRate - (Integer * 16);
LINFlexD_0.LINIBRR.R = Integer;
LINFlexD_0.LINFBRR.R = Fraction;
LINFlexD_0.LINCR1.B.INIT = 0; /* Exit Initialization Mode */
UARTFirstTransmitFlag_0 = 1; /* Indicate no Tx has taken place yet */
/* Configure LINFlexD_0 TxD Pin. */
SIUL2.MSCR[PB2].B.SSS = 0b0001; //Pad PF14: Set to LINFlex_0 TxD. Must choose this option because F14 leads to LIN PHY of motherboard
SIUL2.MSCR[PB2].B.OBE = 1; //Enable output buffer
SIUL2.MSCR[PB2].B.SRC = 3; //Full drive-strength without slew rate control
/* Configure LINFlexD_0 RxD Pin. */
SIUL2.MSCR[PB3].B.IBE = 1; //Pad PF15: Enable input buffer
SIUL2.IMCR[165].B.SSS = 0b0001; //Connect LINFlexD_0 signal to PTB3
}
Did anybody faced this error, if yes how to solve it?
Thanks in advance,
Vella
Hi,
do you have LINFlex_0 clocked through ModeEntry module?
You can refer to this example https://community.nxp.com/docs/DOC-104681
