am335x linux3.2.0內核 編譯Graphics_SDK_setuplinux_4_09_00_01_hardfp_minimal_demos.bin
注：sd卡啓動盤插入到ubuntu10.04，sd卡顯示的目錄是/media/rootfs
一、Ubuntu 10.04 LTS 32位系統下安裝ti-sdk-am335x-evm-06.00.00.00-Linux-x86-Install.bin
ubuntu-10.04-desktop-i386.iso下載地址:
http://old-releases.ubuntu.com/releases/10.04.0/
ti-sdk-am335x-evm-06.00.00.00-Linux-x86-Install.bin下載地址：
http://software-dl.ti.com/sitara_linux/esd/AM335xSDK/06_00_00_00/index_FDS.html
安裝ti-sdk-am335x-evm-06.00.00.00-Linux-x86-Install.bin到/home/username/ti-sdk-am335x-evm-06.00.00.00
二、編譯linux內核
參考http://software-dl.ti.com/sitara_linux/esd/AM335xSDK/06_00_00_00/exports/sitara-linuxsdk-sdg-06.00.00.00.pdf
cd /home/username/ti-sdk-am335x-evm-06.00.00.00/board-support/linux-3.2.0-psp04.06.00.11
export PATH="/home/username/ti-sdk-am335x-evm-06.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin:$PATH"
To clean the kernel:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- mrproper
To build SDK configuration for AM335x:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tisdk_am335x-evm_defconfig
To build uImage target:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage
To build modules:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules
安裝內核
sudo make ARCH=arm INSTALL_MOD_PATH=<path to root of file system> modules_install
示例：sudo make ARCH=arm INSTALLMOD_PATH=/media/rootfs modules_install
三、編譯Graphics SDK(Graphics_SDK_setuplinux_4_09_00_01_hardfp_minimal_demos.bin)
安裝Graphics_SDK_setuplinux_4_09_00_01_hardfp_minimal_demos.bin到/home/username/Graphics_SDK_4_09_00_01
cd /home/username/Graphics_SDK_4_09_00_01
export ARCH=arm
vi ./Graphics_SDK_4_09_00_01/Rules.make
HOME=/home/username
GRAPHICS_INSTALL_DIR=${HOME}/Graphics_SDK_4_09_00_01
CSTOOL_DIR = /home/username/ti-sdk-am335x-evm-06.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin
CSTOOL_PREFIX = arm-linux-gnueabi-
KERNEL_INSTALL_DIR=/home/username/ti-sdk-am335x-evm-06.00.00.00/board-support/linux-3.2.0-psp04.06.00.11
TARGETFS_INSTALL_DIR = /media/rootfs
編譯和安裝
make BUILD=release OMAPES=8.x SUPPORT_XORG=1 PM_RUNTIME=1 all
make BUILD=release OMAPES=8.x SUPPORT_XORG=1 PM_RUNTIME=1 install
修改linux 啓動盤的/etc/profile文件
#export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0
export QT_QPA_PLATFORM=eglfs:fb=/dev/fb0
export QT_QPA_EGLFS_FB=/dev/fb0
export QT_QPA_EGLFS_WIDTH=1024
export QT_QPA_EGLFS_HEIGHT=768
export QT_QPA_EGLFS_PHYSICAL_WIDTH=100
export QT_QPA_EGLFS_PHYSICAL_HEIGHT=100
修改linux 啓動盤的/etc/powervr.ini
ParamBufferSize=33554432
初始化eglfs運行環境
儀器開機後運行 /etc/init.d/335x-demo
