Hi Andrew,

You may need to refresh your environment variables.

To do this, you can try this command at the u-boot prompt: destroyenv

If that does not work, you can manually destroy the environment by using the sf commands: sf probe || sf probe 1 sf erase 0xc0000 0x2000

I'll update the instruction on the web to include this step
