hello jack , thanks for your reply, to create a kernel image for beagle bone black i referred the following sites [1] http://elinux.org/Building_BBB_Kernel#Downloading_and_building_the_Linux_Kernel and [2] http://wiki.beyondlogic.org/index.php/BeagleBoneBlack_Building_Kernel from this two link they said
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnu- uImage-dtb.am335x-boneblack will create a kernel image for beagle bone black but when i try to export above make command i got the "no rule to make target " error message procedures i followed to create a kernel image ================================= i download separately beaglebone-defconfig and firmware file To download the kernel source (3.8.13) i used compressed file from kernel.org because for me if i use the patch.sh script to download the kernel source would take more than 7 hrs due to proxy and limited speed of network To compile the code i followed the procedure from [1] www.elinux.org site output from beagle bone black ======================= my actual output from board was U-Boot> setenv autoload no U-Boot> setenv ipaddr 192.168.1.61 U-Boot> setenv serverip 192.168.1.69 U-Boot> setenv bootfile uImage U-Boot> setenv tftpblocksize 512 setenv bootargs mem=32M console=ttyO0,115200n8 root=/dev/ram0 rw initrd=0x80007FC0,4M ipaddr=192.168.1.61 serverip=192.168.1.69 U-Boot> setenv bootcmd ‘tftp 0×80200000 uImage; tftp 0x80007FC0 rootfs.img.gz;bootm 0×80200000 ‘ U-Boot> tftp 0×80200000 uImage; tftp 0x80007FC0 rootfs.img.gz;bootm 0×80200000 link up on port 0, speed 100, full duplex Using cpsw device TFTP from server 192.168.1.69; our IP address is 192.168.1.61 Filename ‘uImage’.
