After I boot-up Brutus with Arm-linux, and run the Nano-X, it says: Cannot bind to named socket: Invalid argument. And then I tried to run the bin/world directly('coz I opt LINK_SERVER_WITH_APP Y), it's also erro. It says: Error opening /dev/fb0: No such file or directory Cannot initialise screen: No such file or directory Cannot open graphics How to get a /dev/fb0?? My arm linux version: 2.2.14, gcc-2.95.2, glibc-2.1.2, binutils-2.9.5.0.22. Hope anybody can give me some clues. I change following setting of original microwin/src/config: ARCH = LINUX-ARM OPTIMIZE = N SCREEN_PIXTYPE = PF_TRUECOLOR332 LINK_APP_INTO_SERVER = Y FRAMEBUFFER = Y FBVGA = Y VTSWITCH = Y PORTRAIT_MODE = N NOMOUSE = Y SA1100_LCD_LTLEND = Y | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Hope anybody can give me some clues. 2.2.14 must be setup to support framebuffer. The framebuffer HOWTO is in microwin/src/INSTALL. However, make sure that you have the following set in your kernel .config, or /dev/fb0 can't be opened, which means you don't have a framebuffer: CONFIG_FB=y CONFIG_DUMMY_C ONSOLE=y CONFIG_FB_xxx=y where xxx is your kernel hw for framebuffer support CONFIG_FBCON_ADVANCED=y and then the CONFIG_FBCON_CFB8=y and others to match your framebuffer resolution. If your kernel isn't compiled right, /dev/fb0 open will fail, just like you're getting.

If you've compiled your Kernel using the default configuration settings for the brutus board; ie. make brutus_config then you will almost certainly have framebuffer suport. What I suspect you need to do is create the framebuffer device before you run your demos. ie. mknod /dev/fb0 c 29 0 Of course, if you updated your Ramdisk you wouldn't need to do this each time you want to use the framebuffer device. I would suggest you try this before re-compiling your kernel.

I use the following source, kernel 2.2.14, gcc 2.95.2, glibc-2.1.2, binutils-2.9.5.0.27. The gcc and binutils are normally built. However, when I build the glibc, the make process is out with this error "/usr/local/arm/bin/ld: unrecognized emulation mode: elf32arm Supported emulations: armelf_linux armelf_linux26 armelf" Could anyone tell me why?
