Hi Krishna,
Yes, you can, of course, use Embedded Wizard with your individual custom build and hardware. However, when you do this for the RaspberryPi, then you need to ensure that the proper OpenGL/EGL drivers are also included in your build because the Platform Package for the RaspPi depends on those. If your hardware does not support OpenGL drivers, then another Linux Platform Package (then using only the Linux framebuffer) should be used. Please get in contact with us directly if you are looking for such an adaptation. Hope that helps...
Best regards,
Manuel
