you didn't save the environment, so the default environment is
used.

Please check 'bootargs' environment variable (print bootargs).
It should contain "console=ttymxc0,115200" among other values.
Probably this is not set in the default environment and is missing.
Ensure that you are passing the correct console string for your
board in bootargs. I'm not sure if ttymxc0 is correct, please
test it first.
