I had no idea I was engaging so many people.

The problem has resolved to a Python versioning issue, and has been solved. This was aggravated by the fact that when Python is invoked by issuing a shell command to ‘call’ a *.py file, the mapping to python version follows the Windows shell when one of the EDK shell variables is not initialized – I think it was PYTHON_COMMAND, but I don’t remember. Basically, Windows has an opinion about which Python to invoke when BUILD.BAT executes this line:

@%PYTHON_COMMAND% %BASE_TOOLS_PATH%\Source\Python\%ToolName%\%ToolName%.py %* .

So, I was bitten by a Python 😝

Thanks to all of you for your assistance. UEFI spelunking can be a lonely art. It’s nice to meet other travelers.

Oh, and I was using tag 202002. We don’t need no steenkin’ upgrades!

This issue has been fixed in edk2 trunk. Can you try the latest edk2?

Thanks

Yup, I was tired. Read the Python version all wrong.

So, the problem is here.

File "C:\EDK2020\district-defend\edk2\BaseTools\Source\Python\Common\Misc.py", line 1638, in __init__

    if ByteArray.tostring() != b'PE\0\0':

see:

https://docs.python.org/3/whatsnew/3.9.html

array.array: tostring() and fromstring() methods have been removed. They were aliases to tobytes() and frombytes(), deprecated since Python 3.2. (Contributed by Victor Stinner in bpo-38916.)

you could try python 3.8 or cherry pick this change.
