Well now I had time to solve the problem once and for all. If I look back the solution was so simple. Because we use a .bat and .tcl file to copy all on the NAND-Flash we haven't set the active ENV-Block (one redundant and one in use). Now I simply ad the flag set in the .tcl file and it works:
################################################################################ # proc uboot_env: Convert u-boot variables in a string ready to be flashed # in the region reserved for environment variables ################################################################################ proc set_uboot_env {nameOfLstOfVar} { upvar $nameOfLstOfVar lstOfVar
# sector size is the size defined in u-boot CFG_ENV_SIZE set sectorSize [expr 0x20000 - 5] set flag 1 <- I added this
set strEnv [join $lstOfVar "\0"] while {[string length $strEnv] < $sectorSize} { append strEnv "\0" } set strCrc [binary format i [::vfs::crc $strEnv]] return "$strCrc$flag$strEnv" <- and the $flag }

Well, until now I haven't got any problem with this solution.
You probably don't have a problem but your customers will get them. I wish you some luck when your product goes to mass production if you neither have found out why your environment storage has problems nor if you don't have any error recovery.
With best regards Andreas Schweigstill
PS.: If you need a consultant which does some forensics on your failed products and is able to find a quick and clean(!) solution don't hesitate to contact me. ;-)
