Linux AVR environment

All listed programs are available from the CD which comes with the usb500 programmer, or can be downloaded from the Internet.

Fisrt step, is to create a directory where programs are installed. This is essential, since you want to have a separeta place for MCU tools, and other local porgrams.

# mkdir /usr/local/avr

# mkdir /usr/local/avr/bin
# export PATH=/usr/local/avr/bin:${PATH}

If you want to add the PATH variable permanently, you should add the last line to your ~/.bashrc file.

GNU binutils

Binutils is a bunch of programs which needed to make objects.

Run the following commands to build and install the binutils:

$ tar -jxvf binutils-2.16.tar.bz2
$ cd binutils-2.16/
$ mkdir obj-avr
$ cd obj-avr
$ ../configure --target=avr --prefix=/usr/local/avr --disable-nls
$ make

# make install

Add the line /usr/local/avr/lib to the file /etc/ld.so.conf and run the command /sbin/ldconfig to rebuild the linker cache.

AVR gcc

avr-gcc is the C compiler.

Run the following command to build and install it:

$ tar -jxvf gcc-core-3.4.5.tar.bz2
$ cd gcc-3.4.5

$ mkdir obj-avr
$ cd obj-avr
$ ../configure --target=avr --prefix=/usr/local/avr --disable-nls --enable-language=c

$ make

# make install

AVR C-library

Run the following command to build and install it:

$ tar -jxvf avr-libc-1.4.3.tar.bz2
$ cd avr-libc-1.4.3
$ ./configure --prefix=/usr/local/avr/ --build=`./config.guess` --host=avr

$ make

# make install

After this last step is compleeted, you have the environment installed! Next step is to have a 5 minutes programmer! First, install uisp, which is a programmer software.

UISP

$ tar jxvf uisp-20050207.tar.bz2.tar
$ cd uisp-20050207
$ ./configure --prefix=/usr/local/avr
$ make

# make install

Building the 5 minutes programmer

You need a DB25M connector, and a couple of resistors. Wire them up according to the following table.
