Hello,
I would like to ask how framebuffer uses processor graphics in term of memory and display refresh.
for example, does it need to image need to be written info frambuffer again and again or is it suffecient to write it only once ?
The question arise from a behaviour in which thw iimage disappear after a split of a second when doing things such as :
> cat mybmp.bmp > /dev/fb0
I am not sure if this problem is a matter of display timing issue or wrong usage of fbdev.
Regards,
Ran
