nrfutil.exe UnicodeDecodeError

[Darren16]

when I use nrfutil.exe to generate .zip file on win10 64bit, I got the UnicodeDecodeError.

Traceback (most recent call last):
File "__main__.py", line 303, in <module>
File "click\core.pyc", line 664, in __call__

File "ntpath.pyc", line 108, in join
UnicodeDecodeError: 'ascii' codec can't decode byte 0xb4 in position 9: ordinal not in range(128)

how should I solve this problem?

Sorry for not coming back to you previously.

I have checked with the source, and that particular part of the code handles the working directory and the file name. My best guess is there might be problems if either the path or the file name has non-ascii characters. I'll do some testing.

I did some testing using paths and file names with accents. I did get some errors originating from the same function, but at a later point. It would be interesting to know what was your working directory and file name when you got this error, to try to reproduce.

[Darren16]

the file name looks like "test_one-1.hex", and it is on the desktop.

[tesc]

If it is on your desktop then your username will be part of the path ( it will be something like "C:\Users<user name>\Desktop").

• Are there no ´ characters (or letters with that accent, or any other non-[a-z] characters) in your username as well?
• What file name (and possibly also path) are you giving to the zip file?
• From what path are you running nrfutil.exe?
• What is your full nrfutil.exe command?

I guess the problem is that my is chinese. I run nrfutil.exe at desktop, the command has no error. "nrfutil dfu genpkg --application **.hex --application-version 0xFFFFFFFF test.zip"
