Right - it needs two more flash blocks. > Which raises the question: why is the environment so large? Wouldn't a > few kB be enough (4kB, 16kB for example)? NAND flash cannot be erased in arbitray sizes, but only in blocks; on the TX25 the erase block size is 128 kB. So with redundant environment we need two block for the U-Boot code, and two more for the 2 copies of the environment = a total of 512 KiB.
