文件操作返回值为-2005

采用的处理器为CC3235S，编译环境为CCS9.2.0

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

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

好的，谢谢啦

请问有CC3235S的功能方框图嘛

请看手册：https://www.ti.com.cn/cn/lit/ds/symlink/cc3235s.pdf?&ts=1590048517938
