Hi Anusha,  
Can you provide the API call recording file for this error for me to investigate this issue?  
the rough usage for the compressed texture should like the following.  
Call UID 26: glGenTextures (1 , 1)  
Call UID 27: glBindTexture (GL\_TEXTURE\_2D , 1)  
Call UID 29: glCompressedTexImage2D (GL\_TEXTURE\_2D , 0 , GL\_COMPRESSED\_RGBA\_PVRTC\_4BPPV1\_IMG , 256 , 256 , 0 , 32768 , ~Image(32768 bytes)~)

Please check if there is any error message:D

Thanks,  
Kevin
