Hello all,
I am also using pin 3 and 4 for I2C interface i connected jumper J2 and J3 to pin 3 and pin 4 respectively,
But still i am no able to read the value from sensor whereas when i use the pin 1 and pin 2 it works properly
the below is configuration in pinmux.c file while using pin 1 and pin 2
//
// Enable Peripheral Clocks
//
MAP_PRCMPeripheralClkEnable(PRCM_GPIOA1, PRCM_RUN_MODE_CLK);
MAP_PRCMPeripheralClkEnable(PRCM_GPIOA2, PRCM_RUN_MODE_CLK);
MAP_PRCMPeripheralClkEnable(PRCM_UARTA0, PRCM_RUN_MODE_CLK);
//
// Configure PIN_64 for GPIOOutput
//
MAP_PinTypeGPIO(PIN_64, PIN_MODE_0, false);
MAP_GPIODirModeSet(GPIOA1_BASE, 0x2, GPIO_DIR_MODE_OUT);
//
// Configure PIN_15 for GPIOInput
//
MAP_PinTypeGPIO(PIN_15, PIN_MODE_0, false);
MAP_GPIODirModeSet(GPIOA2_BASE, 0x40, GPIO_DIR_MODE_IN);
//
// Configure PIN_55 for UART0 UART0_TX
//
MAP_PinTypeUART(PIN_55, PIN_MODE_3);
//
// Configure PIN_57 for UART0 UART0_RX
//
MAP_PinTypeUART(PIN_57, PIN_MODE_3);
//*************I2C****************
//
//
// Configure PIN_01 for I2C0 I2C_SCL
//
MAP_PinTypeI2C(PIN_01, PIN_MODE_1);
//
// Configure PIN_02 for I2C0 I2C_SDA
//
MAP_PinTypeI2C(PIN_02, PIN_MODE_1);
//**********************************
And these are the changes i made when using pin 3 and pin 4
//
// Enable Peripheral Clocks
//
MAP_PRCMPeripheralClkEnable(PRCM_GPIOA1, PRCM_RUN_MODE_CLK);
MAP_PRCMPeripheralClkEnable(PRCM_GPIOA2, PRCM_RUN_MODE_CLK);
MAP_PRCMPeripheralClkEnable(PRCM_UARTA0, PRCM_RUN_MODE_CLK);
//
// Configure PIN_64 for GPIOOutput
//
MAP_PinTypeGPIO(PIN_64, PIN_MODE_0, false);
MAP_GPIODirModeSet(GPIOA1_BASE, 0x2, GPIO_DIR_MODE_OUT);
//
// Configure PIN_15 for GPIOInput
//
MAP_PinTypeGPIO(PIN_15, PIN_MODE_0, false);
MAP_GPIODirModeSet(GPIOA2_BASE, 0x40, GPIO_DIR_MODE_IN);
//
// Configure PIN_55 for UART0 UART0_TX
//
MAP_PinTypeUART(PIN_55, PIN_MODE_3);
//
// Configure PIN_57 for UART0 UART0_RX
//
MAP_PinTypeUART(PIN_57, PIN_MODE_3);
//*************I2C****************
//
//
// Configure PIN_01 for I2C0 I2C_SCL
//
MAP_PinTypeI2C(PIN_03, PIN_MODE_5);
//
// Configure PIN_02 for I2C0 I2C_SDA
//
MAP_PinTypeI2C(PIN_04, PIN_MODE_5);

Thanks and Regards
