Welcome to Cypress Forum.
From the error message in snapshot, it seems the post-build is not configured properly.
Please check the build settings in uVision(which version you are using?) regarding the Post Build.
For complete instruction:
Refer PSoC Creator Help -> Exporting a Design to 3rd party IDE -> Exporting a Design to Keil uVision -> Opening Generated CMSIS-Pack Projects (µVision 5 IDE)->Post Build Script
Thank you for reply.
However, I found no content in PSoC Creator Help -> Opening Generated CMSIS-Pack Projects (µVision 5 IDE) as help.jpg in attachment shown. Moreover, when I export the project to keil, a pop-up window said "Generated CMSIS-Pack Projects" is evaluated, shown in export_IDE.jpg.
I enclosed the project, so would you help me find the configuring issue?
