Hi All, Do we have Mini2440 with 128MB or 256MB SDRAM. I tried google but could not find any. Regards Saravana
Do we have Mini2440 with 128MB or 256MB SDRAM
None !!!!! you may have a mini2440 with 128 , 256 or 1gb of NAND , but is far as I know you have always 64meg of ram.

I believe the other comments are correct all units have 64M SDRAM and 2MByte Nor Flash (for BIOS). If you look at the nand flash chip it can have one of the following numbers: K9F1208 > 64 MB NAND Flash K9F1G08 > 128 MB NAND Flash K9F2G08 > 256 MB NAND Flash K9F8G08 > 1024 MB NAND Flash Also a very good bit of info is from andahammers FAQ web page: "The 64Mbyte NAND Flash has a read/write block size of 512 Bytes and an erase block of 16K. The 126, 256, 1024M parts have page read/write size of 2K and erase blocks of 128K. So, 128, 256, and 1024 (1G) are identical in usage. The latest versions of u-boot test the environment and pass boot parameters so Linux knows which memory it is using. In other situations, like Windows CE6.0, images are generated specifically for the two memory parameters. Only two images are needed: one for 64M, and one for all others."

There were plans to make 128M RAM Mini2440's at one time. My understanding is that the SDRAM chips that are needed were discontinued by all manufacturers except Micron, and with a single source, it was decided to be too risky. The next generation of Samsung chips like the S3C2416 and S3C6410 use DDR and can easily have more RAM.
Thanks all for the info. What dev board you will suggest for Andorid other than mini2440 and min6410. I really need to run Android at decent performance for my Product. Regards Saravana
