Image into Framebuffer

deepanrajanbara — Thu, 09 Feb 2017 10:51:32 GMT

Ours is a custom board based on imx6 .We wanted to dump a image into the framebuffer,But this should be done without opening the /dev/fb0 node.This method is similar to the boot up logo which is copied into the framebuffer base address.

But we are not able to find how they are copying the buffer into the framebuffer base address.Can any one help on how to do so.

Thank you,

Actually in this examples they seemed to open the /dev/fb0 and try to output image into framebuffer.But what i wanted is to output image into framebuffer without opening the /dev/fb0 i.e write the image buffer into the framebuffer RAM address
