Compiling the kernel of Beaglebone black

Question

I followed the procedures to compile the kernel for beaglebone black git clone git://github.com/beagleboard/kernel.git

cd kernel
git checkout 3.8
./patch.sh
cp configs/beaglebone kernel/arch/arm/configs/beaglebone_defconfig
wget http://arago-project.org/git/projects/?p=am33x-cm3.git\;a=blob_plain\;f=bin/am335x-pm-firmware.bin\;hb=HEAD -O kernel/firmware/am335x-pm-firmware.bin
cd kernel
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- beaglebone_defconfig -j4
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage dtbs LOADADDR=0x80008000 -j4
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage-dtb.am335x-boneblack LOADADDR=0x80008000 -j4

when i try to compile this step:

$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage-dtb.am335x-boneblack LOADADDR=0x80008000 -j4, i got the following error:

make: *** No rule to make target `uImage-dtb.am335x-boneblack'. Stop.

without this uImage-dtb.am335x-boneblack file i'm not able to boot the image from board

if any one faced such issues ..help to resolve this resolve

Try putting only uImage in the make target instead of uImage-dtb.am335x-boneblack and once the uImage is obtained, rename it to uImage-dtb.am335x-boneblack. — raghav3276

Check the results of the "patch.sh" script. It is possible that the patch.sh script failed because you did not have the git user.email configuration set. Here was the error I received:

Switched to a new branch 'tmp-patching-branch-sha'
v3.8.13
/home/tkawamura/Development/kernel/patches/dma/0001-Without-MACH_-option-Early-printk-DEBUG_LL.patch:
*** Please tell me who you are.

Run

  git config --global user.email "[email protected]"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'tkawamura@kawamura-ubuntu.(none)')
You need to set your committer info first

I was able to set my user.email and rerun patch.sh. Once completed, my compile of uImage-dtb.am335x-boneblack was successful.

Hope that helps!
