The problem is I can't set bootargs(ipaddr,serveraddr) in the command line,so
the EVM board can't ping my host PC.
After executing "saveenv" command,
the serial port is always showing "erasing nand",
so the new added boot arguments can't be writen into flash.
Is the nand flash writing protected? If it is, how to change it?
Below are content after command "printenv"

.scr on the card; echo Refer to the User Guide on how to generate the image; fi;
