csl 3.01 SD card例程JTAG仿真和烧到Flash后运行有差异

Yang Xiao6

您好，

我用CCS4跑这个例程（C:\c55xx_csl_3.01\ccs_v4.0_examples\mmc_sd\CSL_MMCSD_SdCardFSExtExample），一切都OK。SD card的数据也OK。但是我尝试将.out文件用命令生成.bin文件后，烧写到Nand Flash当中，程序出现了一些很不合逻辑的事情。以下是我的代码，我为了确定程序执行逻辑，加了LED灯闪烁。

本来按照逻辑，我是不需要再SD card initialization Successful这个打印之前加LED闪烁。因为后面程序出错或者成功的地方我都加了LED闪烁，用闪烁次数来表示出什么错或者成功运行。但是程序运行以后，LED一直没有闪烁，这让我很迷惑，我怀疑程序死在了 configSdCard里面，为了确认这个想法，我在SD card initialization Successful的前面加了LED闪烁，但是奇怪的事情发生了，我加完以后，程序居然能够一直运行到了在读写成功的那个地方LED闪烁了5次。由于我的板子串口输出有问题，所以我只能通过LED来判断。请帮忙分析一下这个问题，多谢！
