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 }

Maybe it isn't the best solution but it works ;) Thanks for you help!!

please Debug the function which i mention earlier. If you don't get any clue, please copy the code of your Dataflash_Select() here
Thanks, Seetharam

Thanks Destrukto
Hi,
If I remember correctly, i got the same issue on AT91SAM9263ek.
you please debug the Dataflash_Select() ... there u many need to go into the if condition and do valid=1;
so, please check it once and modify the condition...
u may get the solution ..
