[U-Boot] [U-BOOT] error: end address not on sector boundary when I use saveenv cmd

[U-Boot] [U-BOOT] error: end address not on sector boundary when I use saveenv cmd

[Penda, Naveen Kumar]

Hi All

 When I set all the environment variable and try to save on flash ,
 I am getting Error: end address not on sector boundary. 
 But still my kernel boots with the env setting I made,
 but on restart these enviroment settings are lost.
 Can someone let me know where it could have gone wrong?

Regards
Naveen

Check the settings in your config file. The environment
must live in an integer number of sectors, and sector size
depends on the flash chip (usually 64k or 128k).

saveenv failed, but in-memory env has been modified.

That's because saveenv failed, next time you read environment
from flash (or, most likely, compile defaults). 

hope this helps

Hi Rubini 

  I already looked at my  config file, but couldn't root cause the problem
  Here are some of the definitions from my configs, incase anything wrong 
  Can you please help me.

   NOR Flash:
     CONFIG_SYS_FLASH_BASE  0x10000000
     CONFIG_ENV_ADDR        0x10040000 
     CONFIG_SYS_MAX_FLASH_SECT 512 // Maximum number sectors
     CONFIG_SYS_MAX_FLASH_BANKS 1   
     CONFIG_SYS_MONITOR_LEN SZ_256K   
                NOR_SIZE   SZ_128M   //128MB NOR
                SECTOR_SIZE SZ_256K  // 256KB sector size

Ok. But you'd better copy whole lines from config file instead of
choosing words from them. Sometimes the error is in the details.

(the comment is redundant here)

so the environment is in the second sector (it starts at the
beginning of a sector). You problem is with the end, so
CFG_ENV_SIZE must be wrong in your config. It should be
256k as well.

Alessandro,
  Thanks for your quick support,
  Now I made CFG_ENV_SIZE to proper sector size.
  It is working fine.

Dear "Penda, Naveen Kumar",

You must be using really obsolte code if you still have any CFG_
settings in your code. We got rid of these a long time ago.

Ya, I was using old uboot code, now migrating to the latest u-boot, during this course I was facing these issues.
