Physically, flash memory is arranged into sectors.  Logically, we 
arrange the flash into partitions.  One such partition contains u-boot's 
saved environment.

U-boot is complaining because the partition nominated for this saved 
environment is not aligned to a physical sector boundary.  This is a 
problem because sectors are the minimum unit for flash erase operations.

If you go into the main menuconfig, under user/vendor settings -> system 
configuration -> flash partition table, you will see the default flash 
partition layout.

You need to make sure that the sizes of these partitions, is setup in 
such a way that the boundaries of each partition aligns with the 
physical flash sector size.

Given the similarities among the ML40x boards, you would probably do 
well to copy the partition settings that we have provided for the ML401 
design.

Have a look at the file 
petalinux-dist/vendor/Xilinx/ML401/config.vendor, near the top are the 
config strings that define the default partition sizes.

Once you've updated these for your platform, you'll need to rebuild 
u-boot, and try again.

I hope this helps,

John
