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 } Dharmosoth Seetharam wrote: > > > I agree with your comment. !!!! > > cool.. > > Thanks, > Seetharam > > > Destrukto wrote: > Yes!
