Requires a very recent toolchain, because ATmega32U2 is relatively new. - Building: make - Uploading the firmware to a Ben (for flashing with the atusb-pgm cable): make HOST=<hostname> upload Example: make HOST=ben upload HOST defaults to "jlime". - Flashing the boot loader: Prerequisite: avrdude on the Ben. Disconnect the atusb board from USB. Insert the atusb-pgm connector into the Ben. Place the atusb-pgm adapter on the exposed contact pads of the atusb board and push it down. Then run make prog This takes about 30 seconds. If the programming fails with an error message like "Yikes! Invalid device signature.", verify that the atusb-pgm board is properly connected and placed, then try again. - Uploading the application: Prerequisite: dfu-util installed on the PC. Insert atusb into the PC, then run make dfu Note: since the boot loader resets the USB bus after timing out, this operation can fail with a message like "No DFU capable USB device found". Just retry, and it will eventually get through. -------------------------- Making the toolchain: # patches according to # http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&p=789527 # some gcc prerequisites apt-get remove avr-libc gcc-avr binutils-avr apt-get install libmpfr-dev libmpc-dev # binutils wget http://ftp.gnu.org/gnu/binutils/binutils-2.21.tar.bz2 tar xfj binutils-2.21.tar.bz2 cd binutils-2.21 ./configure --target=avr --disable-nls make make install # gcc wget http://ftpmirror.gnu.org/gcc/gcc-4.5.2/gcc-4.5.2.tar.bz2 wget -O gcc_452_avr.patch http://gcc.gnu.org/bugzilla/attachment.cgi?id=23050 tar xfj gcc-4.5.2.tar.bz2 cd gcc-4.5.2 patch -p1 -s <../gcc_452_avr.patch mkdir obj-avr cd obj-avr ../configure --target=avr --enable-languages=c \ --disable-nls --disable-libssp --with-dwarf2 make make install wget http://download.savannah.gnu.org/releases/avr-libc/avr-libc-1.7.1.tar.bz2 tar xfj avr-libc-1.7.1.tar.bz2 cd avr-libc-1.7.1 ./bootstrap # the automake at the end takes a while ./configure --build=`./config.guess` --host=avr make make install
