Compilation of Davinci kernel image uImage

Compilation of Davinci kernel image uImage 1. copy the directory of the kernel to/root, this prevents other configurations from being damaged. cp/opt/mv_pro_4.0/montavista/pro/devkit/lsp/ti-davinci/root/-rf 2. enter the copied Directory: cd/root/ti-davinci (// or a level-1 Directory, which should contain arch and so on) 3. make menuconfig (A Kernel configuration image interface is displayed. open the newly generated configs file arch/arm/configs/davinci_dm644x_defconfig 5. copy the new configuration file to the current directory/root/ti-davinci to overwrite (hide the file ). config cp arch/arm/configs/davinci_dm644x_defconfig. config 6. open again On the configuration page, modify the required configuration parameter make menuconfig 7. make 8. make uImage 9. copy the new uImage from/root/ti-davinci/arch/arm/boot to the file system cp/root/ti-davinci/arch/arm/boot/uImage/tftpboot/ 10. set permission: chmod 777/tftpboot/uImage attached: Compile the kernel and use it in the arm-gcc compiler. You need to set the environment variable: export PATH = "/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin:/opt/mv_pro_5.0/montavista/pro/bin: /opt/mv_pro_5.0/montavista/common/bin: $ PATH "Davinci kernel compilation common commands DM64 46 set the kernel to the default configuration mode: make ARCH = arm CROSS_COMPILE = arm_v5t_le-davinci_dm644x_defconfigmake ARCH = arm CROSS_COMPILE = arm_v5t_le-checksetconfig DM355 set the kernel to the default configuration mode: make ARCH = arm CROSS_COMPILE = arm_v5t_le-policarch = arm CROSS_COMPILE = arm_v5t_le-checksetconfig enter the configuration menu and change the Kernel configuration option: make ARCH = arm CROSS_COMPILE = arm_v5t_le-menuconfig: make ARCH = arm CROSS_COMPILE = arm_v5t_le-uImage kernel module Compilation Command: ARCH = arm CROSS_COMPILE = arm_v5t_le-modules if the mkimage command cannot be found during image compilation, run the following command and run the make command export PATH = $ PATH: /opt/mv_pro_4.0.1/montavista/pro/bin (gcc path required for compiling the kernel) chmod a + x/opt/mv_pro_4.0.1/montavista/pro/bin/mkimage (path of mkimage) make ARCH = arm CROSS_COMPILE = arm_v5t_le-uImage. If not, enable/home/davinci/ICETEKWork/lsp/ti-davinci/scripts/mkuboot. sh file. Assign the MKIMAGE directly to the absolute path of the mkimage. Mine is MKIMAGE =/opt/mv_pro_4.0/mon. Tavista/pro/bin/mkimage, and then run the compile kernel command again...
