This is the wrong approach. Either you misunderstand the format (for example in case of a redundant environment where you have to take the flag byte into consideration), or there is a bug in the implementation of the Allwinner SDK if it creates such a an environment. In any case, it is not legal for the U-Boot environment to have any leading zeros. By definition, a sequence of two NUL-Bytes will mark the end of the environment. You should fix the cause of the problem, and not modify the code to work on random / incorrect data.
