CC3200 I2C 引脚 更改 P01、P02

请教一下TI的工程师， 我想把I2C的引脚设置成P03、P04， 我是这样修改的：

//
// Enable Peripheral Clocks
//
PRCMPeripheralClkEnable(PRCM_GPIOA1, PRCM_RUN_MODE_CLK);

//
// Configure PIN_01 for GPIO Input
//
PinTypeGPIO(PIN_01, PIN_MODE_0, false);
GPIODirModeSet(GPIOA1_BASE, 0x4, GPIO_DIR_MODE_IN);

//
// Configure PIN_02 for GPIO Input
//
PinTypeGPIO(PIN_02, PIN_MODE_0, false);
GPIODirModeSet(GPIOA1_BASE, 0x8, GPIO_DIR_MODE_IN);

//
// Configure PIN_03 for I2C0 I2C_SCL
//
MAP_PinTypeI2C(PIN_03, PIN_MODE_5);

//
// Configure PIN_04 for I2C0 I2C_SDA
//
MAP_PinTypeI2C(PIN_04, PIN_MODE_5);

但读写时提示 错误，I2C_MASTER_ERR_ARB_LOST。

请问这是什么原因？

通过Pin MUX工具直接产生硬件I2C的代码如下：

我是通过Pin MUX工具 产生的， 同时也把P01、P02 作为了一个普通的GPIO口。 

最终还是不行。

求解答

同时也把P01、P02 作为了一个普通的GPIO口？ 你用P01和P02即做I2C又做普通GPIO？ 同一个时间只能配置成一种模式，而且注意I2C需要大约10k的上拉电阻支持。
