Hi Sumit,

Thanks for your message and welcome to the PowerVR Developer Forum!

The error you are getting is related to some instance function pointers from Vulkan not being found. Unfortunately we have not tested our SDK on R-Car devices. Please make sure your device supports Vulkan, also you can add some debug code to find out which function pointers are missing.

Best regards,  
Alejandro
