Hello,
I have a CV860A (VIA C3) motherboard and I would like to build a small
kernel with a small filesystem based on busybox to use it on a compact
flash of 1go. I think that buildroot can be the right way to do it !
I did a first test to build a cpio root fs with grub and a vmlinuz kernel :
BR2_TARGET_ROOTFS_CPIO=y
BR2_TARGET_GRUB=y
BR2_KERNEL_LINUX_ADVANCED=y
BR2_LINUX_BIN_VMLINUX=y
I did the "make", when buildroot ask me to configure the kernel, I
changed nothing and i build this :
------------------
ls -hl output/images/
total 984M
-rw-r--r-- 1 user user 855M 2010-06-24 20:29 rootfs.cpio
-rwxr-xr-x 1 user user 129M 2010-06-24 16:56 vmlinux
------------------
I'm a little bit surprised by the size of the root fs and the kernel. I
chekc the fs and I found that I have a lot of modules but I don't need
of Xserver or wifi driver. How can I know modules that I can select or
unselect in the make linux26-menuconfig" ? Is there somebody who have a
.config to share ?
Moreover, I think that during the building I can preapre the compact
flash to receive the kernel and fs. Have you got a method to do it ?
Thanks for your help.
Best regards
David
