the same failed to set owner root for  /var/volatile/cache/
the same failed to set mode 0755 for  /var/volatile/cache/

I did the following:
root at X:~# chown uucp.uucp /dev/ttyACM0
root at X:~# cu -l /dev/ttyACM0
GTA02v5 #  setenv bootcmd setenv bootargs \${bootargs_base} \${mtdparts}\; 
nand read.e 0x32000000 kernel 0x300000\; bootm 0x32000000
GTA02v5 #  saveenv 
Saving Environment to NAND...
Erasing Nand...GTA02v5 #

If I now choose boot from the bootloader it boots fine,
But after a reboot I have to do the same again it, it doesn't save it.
