Re: [Linux-fbdev-devel] How to use ISRAm as a frame buffer in Linux

[Prakhar V. <pra...@gm...>]

Hi Antonino,

I tried reading the data from framebuffer using cat as u have told, I wrote
the following command:

cat /dev/fb0 > image.txt

Is the command correct or not, as I am getting some corrupted data......
Below is the some part of data, which I am getting:

W<8d>=C3=B5<8c>^U<8d>=C3<8c><8c>c<86>2^D"=C3(c)^Y=C3=AD2=C3*uC[\<9c>d=C3^\m=
^\u]u|}\}}}<9d><85>^?<8^?<85>=C2=BF<8d>=C3<8d>=C3=BE<95>=C3<95>=C3=BD<95>=
=C3=BD<95>=C3=BF<9d>=C3=BF<9d>^_<9e>^_<9e>^_<9e>?<9e>><9e>9d><98>=C2=A5p

And could you please tell me how to get the RGB data from framebuffer.

Thanks And Regards
Prakhar
