dh_init and crypto_mod_exp: clarification

Well, er..yes, i got it wrong.. dh_init() does pass it in big-endian format. What is
puzzling me is that the private key data and dh prime on my machine get corrupted in
the mp_read_unsigned_bin() function. For example the prime in the a->dp[] array looks 
as below (looks corrupted every 4th byte or something..)

Is there some architecture specific porting required in the libtommath ? (I have maintained
all macros as default, including MP_PREC and DIGITBIT). I am running a RTOS on my 120MHz 
ARM9
