Hi All, i am following following issues when using samsung flex-onenand of size 1GB.
1. I am doing following steps, 0) onenand erase force 0x200000 0x6400000 if i erase full onenand my oneboot and uboot also get erased( which are at first block of onenand) i do not know is there different erase command for SLC and MLC. if any body is having idea how to do pls let me know. onenand_erase: start = 0x06500000, len = 131072 onenand_erase: start = 0x06520000, len = 131072 onenand_erase: start = 0x06540000, len = 131072 onenand_erase: start = 0x06560000, len = 131072 onenand_erase: start = 0x06580000, len = 131072 onenand_erase: start = 0x065a0000, len = 131072 onenand_erase: start = 0x065c0000, len = 131072 onenand_erase: start = 0x065e0000, len = 131072 OK a) mtdparts mtdparts ---mtdparts_init--- last_ids : onenand0=onenand env_ids : onenand0=onenand last_parts: mtdparts=onenand:2...@1m(params),8...@2m(kernel),16m(rootfs),32m(fs),- (ubifs) env_parts : mtdparts=onenand:2...@1m(params),8...@2m(kernel),16m(rootfs),32m(fs),- (ubifs) last_partition : onenand0,0 env_partition : onenand0,0 ---list_partitions--- device onenand0 <onenand>, #
