[U-Boot] change root password

[Nuno Cardoso]

hi,

How can I change root password??

I try this:

1) stop u-boot and add "init=/bin/sh" to the bootargs variable;
2) boot
3) passwd -d root (inside shell)


but this doesn't work!!!! When I reboot the machine, I cannot login with a
new password.

Thanks,
Nuno Cardoso.
