during compilation ewfiles.gpdsc file is missing.
In documentation of Embedded Wizard
"After the Embedded Wizard code generation the installed post process will generate a ewfiles.gpdsc file, that controls the Keil MDK-ARM project import."
and I have checked in Project.uvprojx file in Text Mode. Its looking fine.
<gpdscs>
<gpdsc name="G:\STM32F746-Discovery\Template\GeneratedCode\ewfiles.gpdsc">
