A question about Resolution of Framebuffer under uClinux

Do you really want to see the higher resolution on the screen or just watch the framebuffer via the network. If only network, you might want to deactivate the display hardware (supposedly doable by software in the driver), to reduce the memory usage.

Moreover to watch the framebuffer via the network it might be a good idea to use the standard "VNC" protocol. With that you can use a standard VNC client on a PC (any Arch and OS) to connect to your device. Moreover the free VNC software already has compression functions and such nice stuff.

Some time ago I did some tests implementing a VNC server on the NIOS (no-MMU). This did work fine, but I just tried to monitor a dedicated memory region and did not yet define that to be the framebuffer (should be no problem at all, though). Moreover I did not try to send mouse-moves and keystrokes towards the device (should be not too difficult). A more interesting task would be to decide if/when a modified picture needs to be transferred.
