Development tools

Toolchain binaries for Debian

Invoke next line to add rtime cross-dev into packages sources list

echo deb ftp://rtime.felk.cvut.cz/debian unstable main >/etc/apt/sources.list.d/rtime-debs.list

Update packages cache (aptitude update) Check, that libmpfr1ldbl and libgmp3c2 packages are installed and select next packages

binutils-arm-elf
gcc-arm-elf

Installation on non-Debian systems

Download the appropriate packages (.deb) from ftp://rtime.felk.cvut.cz/debian/pool.

Then Use ar x binutils-arm-elf_2.19.50-1_i386.deb and tar -C / -xzf data.tar.gz

Do the same for gcc* package

Older version in tar archive

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

Use the System-Less Framework to develop for this family of microcontrollers. It contains Makefiles for building your applications, code for booting the processor, tolpc tool, which can be now used to load applications into RAM, and lpc21isp tool, which can be used to write the application to the flash.

-=== Getting the software ===
-Actual source code can be downloaded using a [[Git]] tool (you need at least [[Git#Correct_Git_version|version 1.5.3.4]] for submodule support):
-  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
-Later you can update your repository using the command:
-  git pull
-and if you see modification of ''common'' directory also:
-  git submodule update
-Browsing of project sources is also possible via [http://rtime.felk.cvut.cz/gitweb/sysless-lpc21xx.git GIT web interface].
-== Using the sysless framework ==
-To compile the downloaded sources, follow the instructions at [[System less framework#Compiling]]
