TypeError: must be str, not bytes

After having issues with python serial and serial dependencies, I finally got to this error:

Tried both Windows 10 and Arch.

What version of python are you running by chance?

I'm running 2.7.13 on my Pi here, and had no issues running this script. You can run the following and it will tell you python -V

@chunkeey may have some feedback on this issue.

I would need to know the python version. The (MR33 specific) ubootwrite.py script calls for python2.7

  #!/usr/bin/env python2.7

The "TypeError: must be str, not bytes```" error however are likely a result of a python 3.5 or 3.6?.

I had a different error with 2.7 Unfortunately, my MR33 decided to not power on one day when I came back, shortly after I posted the question.

RIP unused MR33.

:disappointed: Any idea what killed it? ESD Damage :zap: ? Wrong polarity on the serial ports (yeah, this is really deadly too, even with relatively low voltages and amps)?

[Turb0Yoda]

Unfortunately I have no idea. It was working when I left for class. I turned it off, hadn't plugged in any serial cable for a week. Came back and it hasn't turned on since.

@TurboYoda going to close this issue out, feel free to re-open as needed.
