Re: [U-Boot] saveenv command erases flash u-boot

rudresh said the following:

i'm using u-boot -1.3.0 in MPC8313 evaluation board, it having a NAND , NOR Flash , u-boot stored in NOR flash. when i do the saveenv , reset command the u-boot is erased. i'm not able to fix this issue. help me to fix this issue

Sounds U-Boot and environment share a flash sector. You'll have to give more info for correct diagnostic: Flash size, sector size, u-boot start address and size, position of environment data and if applicable of redundancy data.
