Hi, everybody:
I'm compiling linux kernel for powerpc in eldk-5.0, the following is the
steps I took:
1. download the denx linux kernel: "git clone
git://git.denx.de/linux-2.6-denx.git linux-2.6-denx"
2. run the environment shell to construct the compile environment. "source
./environment-setup-powerpc-linux"
3. according to the FAQ about eldk-5.0, I modified some Makefile under the
kernel tree, change
the -Os to -O2. I am not sure whether it is right to do this, can anyone
tell me how to modify the compile flags?
4. start the compile:
a. make mrproper
b. make ARCH=powerpc CROSS_COMPILE=powerpc-linux-
86xx/mpc8641_hpcn_defconfig
c. make ARCH=powerpc CROSS_COMPILE=powerpc-linux- uImage
At the end of the compilation, one error is presented:
HOSTCC arch/powerpc/boot/hack-coff
HOSTCC arch/powerpc/boot/mktree
WRAP arch/powerpc/boot/uImage
"mkimage" command not found - U-Boot images will not be built
make[1]: *** [arch/powerpc/boot/uImage] Error 1
make: *** [uImage] Error 2
It seems that something is wrong with U-boot, but this process is about
kernel, why does it report error about U-boot?
Thanks!
