case sensitive folder name in DFS/elmfat parition

[grissiom]

Step to reproduce:

1. On RealBoard4088, create a "SD" folder and mount TF card to it.

msh /SD>ls /
Directory /:
bin                 <DIR>                    
resource            <DIR>                    
upgrade.rb4         478096                   
SD                  <DIR>                    
prog                <DIR>                    

1. reboot and cd sd in msh(note the lower case name).
2. ls will show an empty folder:

msh /sd>ls
Directory /sd:

However, the files in SD/ is OK.

Yes. It's caused by none-case sensitive in FAT file system. There is not a good way to fix it yet.

Isn't this a bug? FAT is indeed case insensitive
