fx3 uart

Hello,

I am trying to print uart messages from fx3 to pc.I am using tx,rx and gnd pins.Pc tx is connected to fx3 rx and fx3 tx is connected pc rx(rs232->usb connector).

uartConfig.baudRate = CY_U3P_UART_BAUDRATE_115200;

uartConfig.stopBit = CY_U3P_UART_ONE_STOP_BIT;

uartConfig.parity = CY_U3P_UART_NO_PARITY;

uartConfig.txEnable = CyTrue;

uartConfig.rxEnable = CyFalse;

uartConfig.flowCtrl = CyFalse;

uartConfig.isDma = CyTrue;

Above parametres defined in fx3 and pc both are same.

For this message, CyU3PDebugPrint (4, "CyU3PDmaChannelCommitBuffer failed, Error code = %d\n", status);

data is printing on teraterm,but data is in other format not as in CyU3PDebugPrint .

thank you.

Hello Geetha,

- As per the firmware, you are using 16-bit configuration in DEFAULT lpp mode that means pins (46:49) are used as UART.

Check that the pins are properly connected.

- And if you are using the integrated debugger, pins (53:56) are connected to the com port and cannot be used for SPI (as in your firmware).

For 16-bit lpp mode should be changed to UART_ONLY.

- For using CyU3PDebugLog() API please refer to FX3 API Guide. It seems the parameters passed are not proper.

- CyU3PDebugPreamble should be added in CyfxdebugInit() function block only.

Regards,

Rashi
