Error when building a image using keyfactor plugin

cleo — Thu, 09 Jul 2026 22:32:02 GMT

I have installed spsdk and spsdk-plugins to build an image for RT1064 using the keyfactor plugin. When I am launching in venv the build_image_win.bat file I keep getting an error

SPSDKError: SPSDK: Signature provider could not be created from config type=keyfactor;url=...

The log file shows the below error.

INFO:spsdk.utils.service_provider:Loading plugins: spsdk.sp
INFO:spsdk.utils.service_provider:SignatureProvider of type keyfactor was not found.
DEBUG:spsdk.apps.utils.utils:SPSDK: Signature provider could not be created from config type=keyfactor;url

I ran a test to inspect the environment's active Python entry points as shown below
"python -c "import importlib.metadata; print([p.name for p in importlib.metadata.entry_points(group='spsdk.sp')])" " and the result of the test is good, keyfactor is in the active Python entry points.

I have attached the build batch file and the yaml file.
How can I fix this issue?

Hi @cleo ，

Looks like the plugin was not loaded successfully. Did you follow the guide from https://github.com/nxp-mcuxpresso/spsdk_plugins/tree/master/keyfactor ? Please refer to https://github.com/nxp-mcuxpresso/spsdk_plugins for more details.

Hope that helps,

Have a great day,
Kan
