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.
Details are as follows .. the flash size 16Mbyte Nor flash.. NAND flash 256MB. /*
- Environment
*/
#if defined(CONFIG_NAND_U_BOOT)
...
#elif !defined(CFG_RAMBOOT)
...
#else
...
#endif
And now you expect me to guess your boot setting?
Assuming neither CONFIG_NAND_U_BOOT nor CFG_RAMBOOT are set: check u-boot image size against 256k, as the offset of environment seems to be set to CFG_MONITOR_BASE + 0x40000
Or is ONFIG_NAND_U_BOOT set (would be the explanation why you mention NAND at all ...)? With u-boot in NOR this indicates a general code/configuration problem in your image.
