about ADSP-SC584 ev board, the spi flash w25q128fv(spi nor flash)  can be replaced by w25m02gv(256MByte spi nand flash)?  if replaced, the system can boot from it?

   

   now we are design audio product based on chip sc584,  we want to large flash size,  assume 256M byte, we assume replace  origin 16MByte spi nor flash, we searched another winbond w25m02gv, it's spi nand flash with 256Mbyte.   but I compare then found,  the flash operation command is different, so how can we do?

 

    and anyone have suggestion?  how to boot the system?   because 584 can't support SD card, and it didn't support DMC0 and DMC1 memory at same time,  we use DMC0 for DDR3 memory,  so DMC1 can't use for Nand flash.

 

    so we use 256Mbyte spi nand flash, the flash save image include boot, linux kernel, file system and sharc image, etc.

so the 584 chip support this spi nand flash is very critical to us, anyone have suggestion?

  thanks!
