I'm trying to flash QCA4020 product develoment kit with demo code of "Power Demo" following doc : 80-YA121-140 on windows 10. 

I configure the path, change USB with ZADIG, added  jumpers, compile code, but I get this error when i try to flash by JTAG/USB

Do you have some idea why I have those errors? Could you please help me?

I have seen this error with the incorrect version of Python.
Are you adding python2.7 to the environment path?
Please check instruction here:

Does your PC have multiple versions of python installed? it might help to move the newer versions lower down the order while using the SDK.

Hope this helps,
