Hello 642142357@qq.com,
Unfortunately we do not have support for exporting projects generated from our toolbox to Keil5 uVision 5 IDE - if you want to bring it there, you'll have to manually set it up (copy the files would be easy, but you'll also have to set the linker files to be used, etc.). The only IDE that we export to is S32Design Studio - for that you'll do a simple import and you'll have everything set-up.
Kind regards,
Razvan.
