I.MX6Q Nand Flash Interface Problem

mithunp_s — Thu, 20 Feb 2014 05:25:44 GMT

Dear All,

One of my customer is using MCIMX6QAICPU1, they want Uboot kernal to run on NOR Flash and File system run on NAND. When we use Micron Flash SLC NAND Flash 8Gbits (1GB) MT29F8G08ABABAWP and tested it is able to recognize Nand Flash and Initialize successfully.

But whey we MLC NAND Flash of 32Gbits (4GB) MT29F32G08CBADA , it is able to recognize nand Flash but while Initializing its getting crash.

Please help to resolve this, please also let us know if this supports 32GB Nand flash.

Regards

Mithun
