Thanks,

I want to know, if i am using the default environment (the that I am using from compilation)
barebox> no valid environment found on /dev/env0. Using default environment

Or I am using the one that there is in /dev/env0

It is in the case someone break something in the NAND flash env, I want to save again the default one.

first try the boot command, if the kernel is not correct (ie : bad
checksum), the boot command returns and you can then launch a tftpboot
or give a prompt.

Check for example :
