你好：
我想使用SRR的範例增加GPIO控制，用來顯示燈號
目前我的作法是在MSS裡的SRR_MSS_initTask增加腳位定義，代碼如下:
Pinmux_Set_OverrideCtrl(SOC_XWR16XX_PINJ13_PADAC, PINMUX_OUTEN_RETAIN_HW_CTRL, PINMUX_INPEN_RETAIN_HW_CTRL);
Pinmux_Set_FuncSel(SOC_XWR16XX_PINJ13_PADAC, SOC_XWR16XX_PINJ13_PADAC_GPIO_1);
Pinmux_Set_OverrideCtrl(SOC_XWR16XX_PINK13_PADAZ, PINMUX_OUTEN_RETAIN_HW_CTRL, PINMUX_INPEN_RETAIN_HW_CTRL);
Pinmux_Set_FuncSel(SOC_XWR16XX_PINK13_PADAZ, SOC_XWR16XX_PINK13_PADAZ_GPIO_2);
GPIO_setConfig (SOC_XWR16XX_GPIO_1, GPIO_CFG_OUTPUT);
GPIO_setConfig (SOC_XWR16XX_GPIO_2, GPIO_CFG_OUTPUT);
static void SRR_MSS_initTask (UArg arg0, UArg arg1)

}
但當我開UI後會出現錯誤訊息，請問是哪裡出了問題??
Nancy Wang：
根据截图中的错误提示，请检查一下设备管理器中的用户/数据端口。

Hi Nancy：
已有重覆進行測試，只要當SRR_MSS_initTask加入這幾段代碼要啟動UI時就會發生錯誤

Chris Meng：
你好，
SRR demo在mms_main.c的SRR_MSS_mssProcessDataPathTask函数里，也有对这两个硬件配置GPIO，请问是否有冲突？
