INTRODUCTION ------------ bkit is meant to be an embedded software developer's toolbox. I have been trying to find a suitable replacement for busybox for embedded linux distributions to provide more choice. The sub-modules of bkit intend to be usable individually. This is to provide more usability as anyone would see fit by making sure its easy to rip something from the main scaffold and use it individually. bkit will use dpkg as the basic packaging system to help resolve dependencies better for targets. The emdebian project does exist and this code could one day be contributed to emdebian. We can also borrow packages for various targets supported currently by emdebian. This would be specific to the Distribution Building kit. GOALS ----- bkit intends to provide the following 1. A Userspace library to simplify embedded application development 2. A Kernel toolkit to simply driver writing for embedded devices 3. A Distribution building kit for Embedded Targets which will be customizable with minimal effort for any specific target. 1. The Userspace Library ------------------------ The Userspace library in turn provides a) System Functions - for memory management - for system profiling b) Data Structure Abstractions c) User Interface Primitives d) A Test Scaffold for all of the above 2. The Kernel Toolkit --------------------- The Kernel toolkit will provide a) Device Driver Templates - for Framebuffer devices - for i2c based I/O control - for 1-wire based control - to provide firmware support - for HID/event driver models b) Profiling and Instrumenting Templates, c) Kernel Tree independent Makefile templates. d) LTP derived testsuite to qualify a linux kernel. 3. The Distribution Building Kit -------------------------------- The Embedded Distro kit will provide a) Cross Compiler Toolchains for - ARMv4, ARMv5, MIPS32, xScale ISAs b) Cross Compiler Script - to build custom cross-compilers c) Packages for use on the Dev-station d) Packages for use on the Target-Platform e) Filesystem building kits supporting ext2, ext3, jffs2, yaffs, yaffs2 f) An extensible bootloader architecture g) Target Deployment tools h) CML2 based configuration environment PLANS ----- With a long list of goals which might take a long time and help from several contributors, there are some ambitious plans to add to the Distribution build kit - A Platform/Machine Simulator - Target Deployment GUI - Multiple JTAG/ICE/Serial/Ethernet Transport Support WHY? ---- Existing solutions like ptxdist have specific designs that create a tightly coupled environment. This has been quite annoying when you wanted to pull out things by hacking through Makefile structures. bkit intends to allow the user to remove an entire block or component and replace it with the user's version with ease. Most projects like crosstool and other toolchain building scripts from emdebian require installation of a full kit. bkit intends to be usable as a whole package or its parts. OpenEmbedded has several packages. However, it is tied down to bitbake and requires some work to remove that dependency. NAME ---- Why "bkit"? Originally the initiative was a small pet-project of mine to be called Betakit. However, later the goals were revised to add so many features that a lone developer would find difficult to deliver to the community. So, a few friends came up with something really simple, "Embedded Kit". After reviewing exactly what we wanted people to do, we wanted to have a unixish name that would mean something close to bake it. Hence to avoid all the naming confusion, the unix name bkit was chosen. LICENSE ------- This entire kit and all its subcomponents are licensed under the BSD License.
