Hi guys,
I have an omap3530 evaluation board. which runs only in text mode.
It doesn't show anything on the display system that it was provided
with. The only way to interact with it is by hyperterminal through
ttyS0.
Now, i want to know what exactly is the role of a frame buffer ?
How does one initialise a frame buffer. ? Because, i made an
application using framebuffer on my host computer.
So, if i do not have the frame buffer running, i cannot run the same
program on my target Board.
Thanks

run linux on it and it will give you a frame buffer...

for a good reading
http://en.wikipedia.org/wiki/Linux_framebuffer
if you have a Text mode LCD (8,16,32,.. columns) frame buffer might not drive any information to it, you can send Text via serial port or parallel port, just like a printer.
If you have a graphic LCD in Text mode, then write to the frame buffer. If you have a Serial Graphic LCD (serial, usb...) then write to serial port.
Would you tell what is your board?
