AT91SAM7S256 newlib problem

Hi there,

i am trying to port the J2ME KVM to an ARM AT91SAM7S256 microcontroller 
...

i want to put the API and the Class Files on an MMC/SD Card ... when i 
try to compile it without the newlib-lpc library i get a linker-error 
that "_stat_r" and "_open_r" are not defined ... if i use the newlib-lpc 
library it needs the device table ...

can anyone help me to create the device_table for MMC/SD (on SPI0)?

or does anyone have an idea how to implement the _open_r and the _stat_r 
functions???

thanks a lot in advance,

greetz from Austria,
