Hi,
I'm implementing flexio uart with pit, but the board is going into hard fault at the first call of enable interrupt or setting timer. I am initializing PIT in my main:
void pit_init(void)
{
pit_config_t pitConfig;
PIT_GetDefaultConfig(&pitConfig);
PIT_Init(PIT, &pitConfig);
}
Then in a library file I'm initializing Flexio UART and PIT interrupts.
uart_init();
PORT_SetPinMux(PORTB, SIM808_PWR, kPORT_MuxAsGpio);
PIT_SetTimerPeriod(PIT, kPIT_Chnl_0, MSEC_TO_COUNT(1000000U, PIT_SOURCE_CLOCK));
PIT_EnableInterrupts(PIT, kPIT_Chnl_0, kPIT_TimerInterruptEnable);
EnableIRQ(PIT0_IRQn);
Here is my uart_init:
void uart_init(void)
{
flexio_uart_config_t uart_config;
FLEXIO_UART_GetDefaultConfig(&uart_config);
uart_dev.flexioBase = BOARD_FLEXIO_BASE;
uart_dev.RxPinIndex = SIM808_RX;
uart_dev.TxPinIndex = SIM808_TX;
uart_dev.shifterIndex[0] = 2U;
uart_dev.shifterIndex[1] = 3U;
uart_dev.timerIndex[0] = 2U;
uart_dev.timerIndex[1] = 3U;
FLEXIO_UART_Init(&uart_dev, &uart_config, FLEXIO_CLOCK_FREQUENCY);
FLEXIO_UART_TransferCreateHandle(&uart_dev, &g_uart_handle, gsm_uart_event_handler, NULL);
}
The exact code where hard fault triggers is "base->CHANNEL[channel].LDVAL = count;". Also is there any example for Parallel Transmit on FLEXIO Bus, please point me to that.
Thanks in advance for help
