Traveo II

Hello Everybody,

with one of a Traveo™ II family of microcontroller, I try to use UART protocol to receive data from external input, I checked that signal is for sure there with oscilloscope, but the interrupt flag is not set with the help of  trace32 environment,  with the following initialization, am I missing something here? thanks in advance.

   for(ucI = 0u; ucI < (uint8)LUART_NO_OF_CHANNELS; ucI++)

   {

      /* disable the serial communication block for configuration */

      Luart_ktConfig[ucI].tChannelReg->unCTRL.stcField.u1ENABLED = 0u;

      /* Program protocol specific information using UART_CTRL registers. */

      Luart_ktConfig[ucI].tChannelReg->unUART_CTRL.stcField.u2MODE = 0x00; /* Standard UART submode */

      Luart_ktConfig[ucI].tChannelReg->unUART_RX_CTRL.stcField.u3STOP_BITS = 1u;

      Luart_ktConfig[ucI].tChannelReg->unUART_RX_CTRL.stcField.u1PARITY = 1u;

      Luart_ktConfig[ucI].tChannelReg->unUART_RX_CTRL.stcField.u1PARITY_ENABLED = 1u;

      Luart_ktConfig[ucI].tChannelReg->unUART_RX_CTRL.stcField.u1LIN_MODE = 1u;

      /* Program generic transmitter (TX_CTRL) and receiver (RX_CTRL) information */

      Luart_ktConfig[ucI].tChannelReg->unRX_CTRL.stcField.u5DATA_WIDTH = 7u;

      Luart_ktConfig[ucI].tChannelReg->unRX_CTRL.stcField.u1MSB_FIRST = 0u;

      /* Program transmitter FIFO (TX_FIFO_CTRL) and receiver FIFO (RX_FIFO_CTRL) information */

      Luart_ktConfig[ucI].tChannelReg->unRX_FIFO_CTRL.stcField.u1CLEAR = 1u;

      Luart_ktConfig[ucI].tChannelReg->unRX_FIFO_CTRL.stcField.u1CLEAR = 0u;

      /* Program CTRL register to enable SCB */

      Luart_ktConfig[ucI].tChannelReg->unCTRL.stcField.u1BYTE_MODE = 1u; /* 8-bit FIFO data elements */

      Luart_ktConfig[ucI].tChannelReg->unCTRL.stcField.u2MODE = 2u; /* UART Mode */

      Luart_ktConfig[ucI].tChannelReg->unCTRL.stcField.u4OVS = 11u; /* over sampling */

      /* interrupt source */

      Luart_ktConfig[ucI].tChannelReg->unINTR_RX_MASK.stcField.u1NOT_EMPTY = 1u;

      /* enable the serial communication block after the configuration is finished.*/

      Luart_ktConfig[ucI].tChannelReg->unCTRL.stcField.u1ENABLED = 1u;

Hello,

Kindly get in touch with Cypress local FAE to test if you have any issue with our uart example.

Best regards,
