Use of SPI boot with a NAND serial flash device

Other Parts Discussed in Thread: OMAPL138

Hello,

I'm designing a board that will be equipped with an OMAPL138 and a NAND serial FLASH, I'd like to use the boot mode "SPI BOOT" but I'm wondering if a NAND serial FLASH device could be used. On the evaluation module (LOGIC) an SPI NOR flash is mounted, however for design reasons I need to use a NAND serial FLASH but using again the serial SPI protcolo both for booting and for flashing. Is there any solution or application report that considers an SPI boot by using a NAND serial FLASH instead of a SPI NOR FLASH?

Thanks for your time,

Bestr regards,

    It depends on the commands required by the NAND serial flash. For SPI boot, the device will simply issue read commands (0x03) and read the data. If the NAND serial flash needs additional commands than that to operate then it will not work with the SPI boot mode.
