TI中文支持网您好，
我们的项目需求是在任何时候都可以读取字库文件和图标文件，当Socket通讯正常时，文件操作没有问题。但是当Socket通讯不正常时，文件操作就会失败，会返回值-2005，对应着错误代码列表查到了#define SL_API_ABORTED (-2005L)，Socket通讯和文件读取没有在一个线程里面，也没有相关性。怎么会出现这种情况呢？请问这是什么导致的呢？
调用方法：
1、图标文件操作
BMPFileHandle = sl_FsOpen((unsigned char *)DeviceFileName, SL_FS_READ, &MasterToken);
RetVal = sl_FsRead( BMPFileHandle, Offset, bmp_data, 0x36);//读取文件头信息
2、字库文件操作
DeviceFileHandle = sl_FsOpen((unsigned char *)DeviceFileName, SL_FS_READ, &MasterToken);
RetVal = sl_FsRead( DeviceFileHandle, Offset, p, FONT_SIZE);

Socket通讯不正常是什么造成的，你有修改过哪里

回复 Kevin Qiu1:
和此前相比，添加了几个标志位，都是用于获取Socekt状态的，并没有在Socket里面运用这些标志位

你是在哪个例程下修改的，可以把具体代码贴出来吗？

您好，
是在network terminal例程下添加修改的

从这个看不出什么，你把文件读写部分的也贴出来
