各位前辈好,想请教一些问题, 目前我在我的板子上有nandflash&SD/mmc card等装置, 一直以来系统是用mmc/sd card来boot的,也用nandflash boot过, 日前换了一颗nandflash,之後却无法把bootImage and jffs2复制到nand上, NAND device: Manufacturer ID: 0xec, Chip ID: 0xd5 (Samsung NAND 2GiB 3,3V 8-bit) mmc/sd开机有侦测到 Scanning device for bad blocks Bad eraseblock 0 at 0x00000000 Bad eraseblock 1 at 0x00080000 Bad eraseblock 2 at 0x00100000 .... ....
