Hi Daniel,
Thank you for your advice.
I am using the same version of the IDE.
I changed the way I saved the SDK and the problem was resolved.
NG pattern:
→ Dowload SDK.
→ Move the zip file to the "C: \ Users \ <User Name> \ mcuxpresso \ 02 \ SDKPackages" folder
OK pattern:
→ Dowload SDK.
→ Launch the IDE.
Drag and drop the zip file into the "Install SDKs" tab.
Thank you very much.
