How to use ISRAm as a frame buffer in Linux

 Hi All,

I would like to read a Image data already present in the framebuffer, as I
am new to this , I am finding it difficult to read. I have written one small
application where I want to read Image pixels value which are present in
Frame buffer.

I am working on linux and also want to use ISRAM as a frame buffer, but
finding it difficult to use it.

Please help me out, if some one know something in this regard. I will highly
appreciate if someone can provide me code snippet for the same. As this will
clear my lots of doubts.

Thanks And Regards
 Prakhar
