hi all,

i am working on OMAP3530,

i have to interface 32Gb NAND flash (4GByte) to GPMC of chip select 0
(CS0).

1) what type of NAND flash can be connected to GPMC, i have to use
this NAND flash for booting purpose as well as mass storage purpose?

thanks and regards

Start with the part that issued on the BeagleBoard C5. Learn about that NAND. Then find the same NAND in a larger device. Then decide wheter you need POP package or the discrete package. Yes, you can use it for booting and storage, just as is done on the BeagleBoard C5.

hi Gerald,

they have used MCP package, NAND + LPDDR, NAND flash is x16, 1.8 v, 256MB and POP.

my problem is , we have selected SLC NAND flash 4GB (part number is MT29F32G08ABAAAWP )(32Gbit), x8, 3.3v, TSOP , how do i interface it to GPMC ?

i have to use this NAND flash for booting and mass storage device purpose.

please suggest me

thanks and regards

You can’t. GPMC is 1.8V. Your NAND is 3.3V.

hi Gerald,
thanks a lot,
now i have selected two 1.8 volts SLC NAND flash’s, x8, 16Gb memory.
but in the board they have used x16 NAND flash, but i am selecting x8 NAND flash.
will it work?

thnaks and regards

hi Gerald,
thanks a lot.
we have one more problem with LPDDR SDRAM interface to SDRC.
we have to interface two 512MB (4Gb) LPDDR’s to SDRC chip selects.
we are struggling to find suitable LPDDR’s from MICRON, please help me , i have attached Micro PLDDR catalog

I am sure Gerald has nothing else to do all day
than reading Micron catalogs for you.....

My suggestion is to contact your Micron sales person and have them suggest a device. Any deviation form what we already have on the Beagle means SW work for you, so you would be best served in really learning all about these devices and their differences so you will be able to write your SW based on the current drivers and how they interact with the current devcies…
