在IDE中怎样编写uClinux上运行的程序

ywt0303125

在IDE中编译hello代码成hello.exe文件后，我把他粘贴到文件系统的bin目录下，然后重新编译文件系统后，下载到开发板上，运行uClinux，在串口工具中进入bin目录，为什么找不到hello.exe文件啊

ywt0303125

我build过文件系统之后才上传的，还是没有，不知道为什么，有一些自带的程序在串口软件用ls命令查看时也没有，例如boa.exe

ywt0303125

在IDE中文件系统bin目录下,我能看到hello.exe,boa.exe等，build之后上传，在传口调式中就看不到了。我选文件系统时差不多都选了，只有两个没选。肯定不是boa，与内核配置文件选择有关吗，与文件系统有关的该选那项呢。

文件上传没有失败啊，上传之后只有部分exe文件在bin目录下

下面是运行的代码

一直是这32个exe文件，其他exe文件显示不出来，再就是自己编写的exe文件也显示不出来，不管原来是全部插入文件系统，还是最小插入文件系统

这是文件系统上传的记录，我把bin目录下的文件删除了几个，上传之后还是有这几个文件。也许我的文件系统是真的上传失败了，我该怎么做，是我的flash有问题吗？怎样才能上传成功啊。

romfs.bin应该没有找错，# Creating .flash file for the datafile
$SOPC_KIT_NIOS2/bin/bin2flash --base=0x00000000 --location=0x0400000 --input=G:/
nios2_5_1/file_system/romfs.bin --output=romfs.flash  这上面还有具体的路径。

怎样将将flash erase掉，自己编写代码擦吗？这可有点困难

ywt0303125

终于成功了，谢谢caopengly 的帮助，有两个文件系统，我明明改了在0x400000是文件系统的起始位置，但是没有变，还是在0x200000位置找文件系统.我也不知道怎么改了。
