Hi, the reason for this problem is the definition of
#define DATAFLASH_BUSY 0x00 #define DATAFLASH_OK 0x01 in the file /include/dataflash.h. All functions return DATAFLASH_OK and in the file /common/cmd_nvedit.c function do_saveenv() return (saveenv() ? 1 : 0); than cause an error. I have modified it to return (saveenv() == 1 ? 0 : 1); and this works for my, but i'am not sure if this is the best way of fixing the problem.

Where is your environment located?

I presume there is a bad return code somewhere. If you have the hush-parser enebled, try this for a start: => if saveenv ; then echo ok ; else echo failed ; fi Saving Environment to Flash...
