This is a only a bug to the test environment:

test/py/u_boot_console_base.py:110:
self.prompt_compiled = re.compile('^' + re.escape(self.prompt), 
re.MULTILINE)

There must not be any byte before the prompt on the line for the test 
environment to recognize it as a prompt.

I will look into the problem.

Best regards
