About glTexDirectVIVMap() in i.MX6DQ.

Dear All,

 

Hello.

When transferring an image to the texture which was created by using glTexDirectVIV(), DMA can transfer it by using glTexDirectVIVMap().

When using a texture and rendering a polygon, the contents of the texture are always updated (i.e.using DMA transfer), in case of calling glTexDirectVIVMap() and DMA transfer's being set.

(When setting a camera image by the DMA transfer in glTexDirectVIVMap(), after that, the contents of the texture are always updated.)

 

[Question]

Is there a way of not making always update the contents of the texture?

 

BSP : L3.14.28_1.0.0

 

Best Regards,

Keita
