LS1043A cfg_rcw_src setting for NAND Flash

ajaykumar_d — Thu, 15 Feb 2018 06:43:09 GMT

Hi I am using LS1043A in my project and want to boot from NAND flash of size 8Gb(1GB). The cfg_rcw_src supported for NAND flash is 4k page and 128 pages/block but the NANDs avilable from Micron and tosiba supports only 4K page and 64pages/block. Is it possible to put some customised cfg_rcw_src setting for 4k page and 64pages/block.

It is possible to use cfg_rcw_src=1_0001_xxxx (8-bit NAND Flash, 4 KB page, 128 pages/block), in U-Boot it is required to specify correct block size - 64 pages.
