I've been using the mini2440 for some time and have been using the mini2440.git repository. Ive been able to successfully build many images and use menuconfig to add/remove drivers etc. Currently I've got myself a 7" screen which I'm hoping to get pygtk running on but am running into a couple of problems. I can build my image just fine here is my .bb recipe: #Angstrom mini2440 gpe image IMAGE_PREPROCESS_COMMAND = "create_etc_timestamp" ANGSTROM_EXTRA_INSTALL ?= "" XSERVER ?= "xserver-kdrive-fbdev" DEPENDS = "task-base task-base-extended \ psplash-zap \ esekeyd u-boot-utils tslib \ i2c-tools i2c screen rsync nfs-utils \ directfb gdbserver directfb mtd-utils \ " IMAGE_INSTALL = "task-base-extended \ ${ANGSTROM_EXTRA_INSTALL} \ psplash-zap \ esekeyd u-boot-utils tslib-calibrate tslib-tests \ i2c-tools i2c screen rsync nfs-utils-client \ directfb gdbserver directfb mtd-utils \ rsvg pango \ ${XSERVER} \ angstrom-x11-base-depends \ angstrom-gpe-task-base \ angstrom-gpe-task-settings \ " IMAGE_PREPROCESS_COMMAND = "create_etc_timestamp" #zap root password for release images ROOTFS_POSTPROCESS_COMMAND += '${@base_conditional("DISTRO_TYPE", "release", "zap_root_password; ", "",d)}' export IMAGE_BASENAME = "maco-gpe-image" IMAGE_LINGUAS = "" inherit image I flash the nand as usual excpet this time i set the mini2440 bootargs variable to 1tb as suggested at http://labs.kernelconcepts.de/Publications/Micro2440/ Everything boots up fine except when I get to the part its suppose to start the gpe-dm i do not get the graphical display and instead i get a console. The same image with the 3.5" touch screen works fine. I've downloaded the support kit from http://labs.kernelconcepts.de/Publications/Micro2440/ which has a angstrom-gpe-image and it booted gdm fine on the 7" screen. With this image I was even able to install and run my pygtk application after installing the necessary packages through opkg and setting DISPLAY=:0.0 I have been doing reseach and read a post about installing X11 on the mini2440 and this is what I've done: modified hw/kdrive/src/kmode.c: //15 is the position in the array #define MONITOR_TIMING_DEFAULT 15 { 800, 480, 72, 50000, 56, 64, 240, KdSyncPositive, 37, 23, 66, KdSyncPositive, }, modified lines 666 to 673 in hw/kdrive/fbdev/fbdev.c, where it says: /* display it on the LCD **** COMMENT OUT THIS CODE */ /* k = ioctl (priv->fd, FBIOPUT_VSCREENINFO, &priv->var); if (k < 0) { perror ("1: FBIOPUT_VSCREENINFO"); return FALSE; } */ $ bitbake -f -c compile maco-gpe-image $ bitbake maco-gpe-image reflashed the mini2440 set uboot bootargs to: setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=ttySAC0,115200 mini2440=1tb (i also tried without mini2440=1tb) When the device is booting i get tux in the top left corner, then the Angstrom splash loading screen, but when gdm-dm starts all i get on the screen is the Angstom login screen in a console environment. when i login and run fbset -i i get the following ouput which looks alright: mode "800x480-50" # D: 23.896 MHz, H: 25.750 kHz, V: 50.000 Hz geometry 800 480 800 480 16 timings 41848 40 40 29 3 48 3 accel false rgba 5/11,6/5,5/0,0/0 endmode I can run ts_test and everything is fine. I just cant get gpe running... Have I done it wrong? Any help would be greatly appreciated. - brendon
GPE on 7" screen
Heres how i got it working: Download the patch files from: http://gitorious.org/opencsbc/openembedded/commit/2475253428f6bedb3552e2... Place the .bb and .inc files in the openembedded/recipes/xorg-xserver directory overwriting the existing files. Place the .patch file in the openembedded/recipes/xorg-xserver/xserver-kdrive directory. Rebuild the xserver and rootfs image: $ bitbake -c rebuild xorg-xserver ; bitbake -c rebuild maco-gpe Reflash the mini2440 with the new .jffs2 image and make sure you set mini2440=1tb in uboot boot args: setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=ttySAC0,115200 mini2440=1tb ; saveenv
