5.4 Linux Kernel

Linux Kernel

The sources for the Linux kernel for Boundary Devices boards are available on

We're currently using branch buntu for Ubuntu support and branch watchie6 for Busybox devel-

opment.

We also supply the source code used to build a given kernel on SD cards in directory /linux-bd.

5.4.1

Kernel conﬁgurations

We currently use conﬁguration nitrogen defconfig for compiling Busybox kernels, and conﬁgu-

ration nitrogen ubuntu defconfig for Ubuntu builds.

5.4.2

For Busybox:

~/linux-bd $ make ARCH=arm CROSS COMPILE=arm-none-linux-gnueabi- nitrogen defconfig

~/linux-bd $ make ARCH=arm CROSS COMPILE=arm-none-linux-gnueabi- uImage modules

For Ubuntu:

~/linux-bd $ make ARCH=arm CROSS COMPILE=arm-none-linux-gnueabi- nitrogen ubuntu defconf

~/linux-bd $ make ARCH=arm CROSS COMPILE=arm-none-linux-gnueabi- uImage modules

In each case, the U-Boot-wrapped kernel (uImage) is located in arch/arm/boot.

You can install the modules into an initrd or nfs ﬁlesystem by using the modules install target

and the INSTALL MOD PATH environment variable:

~/linux-bd $ make ARCH=arm CROSS COMPILE=arm-none-linux-gnueabi- \

Busybox applications and the native compiler from Ubuntu.
