LPC2470 - SDRAM does not work


my design "sample board" is connecting LPC2470 via 32 bit bus SRAM and SDRAM memory. SRAM works very well but SDRAM does not work. I use 2 devices WINBOND W9816G6IH, 512Kx2Banksx16bits. I need urgenly help somebody... how to setting EMC and init SDRAM to start works. SDRAM gets eror reading data after write. I thing init procedure is no right.

Thank you.
