compile bsp: There are two ways. 1). Visual Studio(2005 or newer version), open vs2005.vcproj with visual studio compile, then run it.
2). use scons, open cmd console, change to current path, then do scons -j4 scons will compile this bsp with cl(the compiler of vs), then rtthrad-win32.exe will be created in current directory. Run it by double click it.
run: Run, then you can see the following message on CMD window.

Then you may note that, three file (sd.bin, nand.bin, nor.bin) are created. These three files are used to simulate as SD CARD, nand flash and nor flash. sd.bin--SD card, fatfs, 16M nand.bin--nand flash, uffs, page=2048+64bytes, block=64pages, 16M nor.bin--nor flash, jffs2, block size is 64K, 2M
Note, it failed to mount fatfs,uffs and jffs2, because there is valid partition on sd card, and there is no directory to mount uffs and jffs2.
So, we should mount sd card at first. Press ENTER, and run the command "mkfs", like,
finsh>>mkfs("elm", "sd0")
0, 0x00000000
finsh>>
Then close CMD, and then re-run it. This time, you can see that fatfs is mounted correctly, While uffs and jffs2 are still failed to mount for the reason that there is no any directories for uffs and jffs2. \ | / - RT - Thread Operating System / | \ 1.1.0 build Oct 21 2012 2006 - 2012 Copyright by rt-thread team init jffs2 lock mutex okay hello, world finsh>>fatfs initialized! uffs initialzation failed! jffs2 initialzation failed!
so, in order to mount uffs and jffs2, we should create directories for them. Do the following commands.
finsh>>mkdir("/nand")
0, 0x00000000
finsh>>mkdir("/nor")
0, 0x00000000

Close the CMD console, and restart, then you can see this:

Ok, everything is okay, you can develop rt-thread with visual studio.
