Troubles Again

I have this problem:

My rom at 0x00000000 is an eprom (M27C4002) with data access 16 bits wide.
I have an eprom with an IPL for winCE working.

When using my eprom programmer I read the working IPL I can read some test in
the ILP with the caracter swapped. For example:
I read form the working eprom "ocypirhg t" and I think it is the word
"copyright ".

When I compile my sh-ipl+g I see the text in the rigth way when I open
sh-stub.srec

I'm sure my board is little-endian (we have to remeber it works win winCE).

How can I make myself sure that I'm compiling correctly and I'm writing
correctly the eprom?

Thanks in advance.
