help to write in 2G sd card with arm at91sam7s64 via spi

[mehdi8310021]

hi
i can to write in 1G byte sd card with arm at91sam7s64 via spi. but when i chance it with 2G byte sd cart it does not work.:-(
in initializing sd in 1G byte when arm sents 0x00 to sd the 0x01 respond returns from sd but in 2G byte sd cart the 0xFF respond returns from sd.
this is my codes in spi and mmc/sd initialization
thanks for your think
