After linux boot up I can see my framebuffer in /proc/fb as device 0 0 myfbdriver I am working on 2.6.11 uclinux. What I want to know is ---- what are the option I need to enable in menuconfig in 2.6 kernel for displaying logo on bootup. Currently I tried Device Driver -> Character device -> Virtual Terminal Device Driver -> Character device -> Serial Driver -> Support for console on serial device. Graphic support -> Support of frame buffer devices Graphic support ->Console display driver support -> Frame buffer console support Graphic support ->Logo configuration -> Standard 224-color Linux logo. and My framebuffer driver. After boot linux when I do cat /dev/fb0, I get a logo on my hyperterminal. But console remains blank, I copied other files (.ppm) on /dev/fb0 and its getting written on /dev/fb0 but console remains blank. Can anyone share basic steps for logo display on linux 2.6 ??? I observed that while boot up console gives print .... Console: Dummy colour device 80x25 ..... later when fb driver get loaded, I get following prints Console: switching to frame buffer device 80x30 I have given fix. params as 640x480 but even then it switchs to 80x30. Can any one explain me what going wrong ???? I am not passing any command line params at present also I am not using _setup for command line parsing, is that must ?? One more observation I made when I enable support for logo16 or black&white logo, my driver gets loaded after fbcon and other fb modules, so doing cat /dev/fb0 does not show me anything. thanks Ankur ------------------------------------------------------------------------- Using Tomcat but need to do more?
