Thanks William, I tried to compile kernel 3.13, GFX libraries , all fine. Copied all the stuff on a SD card and booted... well, everything here but screen !
I need to find how to enable LCD4 cape with new kernel. That said, I tried to compile qt4.8.6 with opengl es2 and I have an error: make[4]: entrant dans le répertoire « /home/cedric/qt4-bbb/downloads/qt-everywhere-opensource-src-4.8.6/src/plugins/gfxdrivers/powervr/QWSWSEGL » /home/cedric/bb-kernel/dl/gcc-linaro-arm-linux-gnueabihf-4.8-2014.04_linux/bin/arm-linux-gnueabihf-gcc -c -pipe -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=hard -Wall -W -fPIC -DQT_NO_QWS_CURSOR -DQT_QWS_CLIENTBLIT -I../../../../../mkspecs/qws/linux-TIarmv7-sgx-g++ -I. -I/home/cedric/qt4-bbb/downloads/tslib/src -I/home/cedric/bb-kernel/ignore/SDK_BIN/Graphics_SDK_setuplinux_5_01_01_01/GFX_Linux_SDK/OGLES2/SDKPackage/Builds/OGLES2/Include -I/home/cedric/bb-kernel/ignore/SDK_BIN/Graphics_SDK_setuplinux_5_01_01_01/GFX_Linux_SDK/OGLES2/SDKPackage/Builds/OGLES2/LinuxOMAP3/Include/ -I/home/cedric/bb-kernel/ignore/SDK_BIN/Graphics_SDK_setuplinux_5_01_01_01/include -I/home/cedric/bb-kernel/ignore/SDK_BIN/Graphics_SDK_setuplinux_5_01_01_01/GFX_Linux_SDK/OGLES/SDKPackage/Builds/OGLES/Include -o .obj/release-shared-emb-arm/pvrqwsdrawable.o pvrqwsdrawable.c In file included from pvrqwsdrawable.c:42:0: pvrqwsdrawable_p.h:56:19: fatal error: pvr2d.h: Aucun fichier ou dossier de ce type #include <pvr2d.h> Means no such file, although I have applied patches from https://github.com/prabindh/qt-configs/tree/master/qt4.8 Still trying..... 2014-07-27 23:56 GMT-04:00 William Hermans <[email protected]>: > Cedric, Hi, > > For starters: http://eewiki.net/display/linuxonarm/BeagleBone+Black this > is Roberts "build your own" guide. > > > http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-RootFileSystem%28smallflash%29 > This base image is around 75M in size for me without anything else > installed.
