TI中文支持网各位，大家好：
最近我在使用TI提供的Demo程序serial_flash_programmer对f28335设备进行下载程序，内核程序（Flash_APIV2.1）成功下载并运行，就在用户程序即我自己的DSP程序下载一半的时候下载函数从串口收不到块教研位了，请问有没有遇到过的大哥，指点一下。
程序运行如下：

在我跟踪了VS代码后发现，程序运行到了f05_DownloadImage.cpp文件的int f05_DownloadImage(void)函数的ReadFile(file, &rcvData, 1, &dwRead, NULL);这句代码处一直读到不到内容，所在一直在这里死循环，请大家给我点意见谢谢。
