LPC2470 - SDRAM does not work

Hi,

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.

Hi Matej,
