Hey everyone,

I have Arch running on an embedded system and the specific version of the kernel (3.7.2-2-ARCH) was obtained in an official Arch build disk image

http://archlinuxarm.org/platforms/armv5/olinuxino

so there are no exact kernel sources, that I can find, to be used to reconfigure/compile a new kernel.

I am trying to add dallas 1-wire support that is available in this kernel version but it is not enabled by default.

I have kernel headers in /usr/src/3.7.2-2-ARCH and when I run make menuconfig I do have the dallas 1-wire drivers available, but disabled.

I know I cant compile a new kernel without the kernel source but how can I use the kernel headers to build the dallas 1-wire drivers as kernel modules to be loaded into the running kernel? I do have the kernel config set to allow loadable modules.

Thanks

I do not know how to answer your question. However, having similar tasks in past I've succeeded creating chroot and building the whole OS in a [a more powerful] host system.

Thanks. I actually found the kernel source as an arch pkgbuild and I am in the process of config/compiling the new kernel as an arch package but the new problem is that the system has no boot loader (grub, grub2, lilo, etc.) because it boots the kernel as a /boot/zImage so now I have to sort that out before I can boot to the new kernel.

Hmmm ... I do remember booting kernels 2.0 directly. Nowadays Linux kernels support EFI boot and can be booted directly using (U)EFI. How exactly is this embedded system booting?

Most embedded linux systems (at least the ones that I've played with) use u-boot for a bootloader.

It looks like it uses u-boot
