The Mini2440 platformcode uses a kernel parameter called "mini2440" and not "mini2550" to control the LCD. > I have created a /dev/fb0 and my /sys shows the LCD details What other > device node creations I have to create for this? Don't create device nodes manually. If a device is found by its matching driver the device node gets created automatically. If not, there will be no device node and manually creating one does *not* help. > I manually created /dev/tty* files in the chroot and when I booted the > device I don't see those files. Sure. dev/ is a RAM filesystem. > What seems to be wrong? Don't create device nodes manually! They are useless, because there is no device/driver pair in the background. If you want virtual TTYs you must enable them in the kernel. Regards, Juergen -- Pengutronix e.K. | Juergen Beisert | Linux Solutions for Science and Industry | http://www.pengutronix.de/ |
