I see the new environment in memory (which includes the CRC).
Example:
20000000: 00 00 00 00 00 65 74 68 61 64 64 72 3d 33 61 3a    .....ethaddr=3a:
20000010: 31 66 3a 33 34 3a 30 38 3a 35 34 3a 35 34 00 74    1f:34:08:54:54.t
20000020: 69 6d 65 73 74 61 6d 70 3d 31 32 33 35 00 62 6f    imestamp=1235.bo
20000030: 6f 74 64 65 6c 61 79 3d 33 00 62 61 75 64 72 61    otdelay=3.baudra
...
200001f0: 30 20 30 78 30 30 32 30 30 30 30 30 20 30 78 30    0 0x00200000 0x0

I can also see the default environment with:
U-Boot> env print

I try to load the environment from RAM:
U-Boot> env import -t 0x20000000 0x200
<no errors/warnings>

However, when I try to print the environment again, I see the default
values, and the new imported environment has no effect on the
environment.
U-Boot> env print

What am I doing wrong.
