LPC21xx
Note: The name of this package was recently changed from lpc21xx-boot to sysless-lpc21xx. We have also changed the version control system from Darcs to Git.
Docuemtnation
Development tools
- Download gcc-arm-elf-3.4.3-bin
- Unpack this to the root direcotry
tar -C / -xvzf gcc-arm-elf-3.4.3-bin.tar.gz
Software
Basic development environment for LPC21xx microcontrollers. It contains makefiles for building your applications and code for booting the processor.
We have also developed a tolpc tool, which can be now used for loading applications to RAM. For flash loading lpc21isp can be used. In future we will include flash programming posibility to tolpc.
Getting the software
Actual source code can be downloaded using a Git tool:
git clone git://rtime.felk.cvut.cz/sysless-lpc21xx.git
If you have an acount on the rtime server, you can use ssh-based access to the repository. If an administrator gave you the right for writing to the repository, you can not only read (pull) repository but also write (push) changes to the repository:
git clone <login>@rtime.felk.cvut.cz:/var/git/sysless-lpc21xx.git
For the proper work you need to download and configure additional common files:
cd sysless-lpc21xx git submodule init git submodule update common/linkarch
Later you can update your repository using the command:
git pull
Browsing of project sources is also possible via GIT web interface.
Installation/Compilation
In order to compile sources from the repository and your applications, you need to "merge" the lpc21xx-boot tree to h8300-boot tree. Besides support for h8300 family processors, h8300-boot contains a general makefiles. lpc21xx-boot only contains support for LPC processors and reuses the makefiles from h8300 boot. In future, makefiles will be provided separately.
You need to follow these steps to prepare for compilation of sysless-lpc21xx.
- Download H8300-boot repository to some directory (not under sysless-lpc21xx)
- Change directory to h8300-boot
cd h8300-boot
- Run the script to merge sysless-lpc21xx to the tree.
sh linkarch <path/to/sysless-lpc21xx>
This should create symbolic links to the sysless-lpc21xx in the directory tree. - Follow the instructions for compilation for h8300-boot. Note, that you will execute make commands from the configured h8300-boot tree and not from sysless-lpc21xx tree.
