Hi
I am working on the Rm48 evl board. I am using halcongen generated driver for the sci and other peripherals. i am trying to read and write to the SCI(LIN/sci) either port. i am able to write through the siclinReg but at the time of receive it stuck at the receive "while ((sci->FLR & SCI_RX_INT) == 0U)". i am not able to proceed further on this path. below are configuration i am using
H/W : J11 pin LIN TX and LIN RX. extra connection coming out of the board and connected to to the putty(PC).
driver setting:
void sciInit(void)
{
/* USER CODE BEGIN (2) */
/* USER CODE END */
/** @b initialize @b SCILIN */
/** - bring SCI out of reset */
scilinREG->GCR0 = 0U;
scilinREG->GCR0 = 1U;
/** - Disable all interrupts */
scilinREG->CLEARINT = 0xFFFFFFFFU;
scilinREG->CLEARINTLVL = 0xFFFFFFFFU;
/** - global control 1 */
scilinREG->GCR1 = (1U << 25U) /* enable transmit */
| (1U << 24U) /* enable receive */
| (1U << 5U) /* internal clock (device has no clock pin) */

/** - initialize global transfer variables */
g_sciTransfer_t[1U].mode = 0U << 8U;
g_sciTransfer_t[1U].tx_length = 0U;
g_sciTransfer_t[1U].rx_length = 0U;
/** - Finaly start SCILIN */
scilinREG->GCR1 |= (1U << 7U);
suggest if i am doing wrong on this. i am facing this issue from past few weeks. immediate help will be anticipated.
And one more thing i am facing is i am not able to send any thing on SCI(sciREG). please help us to make this work.
