Proxmark 3 client

• Build the client/bootloader:

sudo apt-get install build-essential libreadline5 libreadline-dev libusb-0.1-4 libusb-dev libqt4-dev perl pkg-config

cd /tmp
wget http://sourceforge.net/p/devkitpro/perlupdaters/ci/master/tree/devkitARMupdate.pl?format=raw -o devkit.pl
chmod devkit.pl
./devkit.pl
export DEVKITPRO=~/devkitPro
export DEVKITARM=${DEVKITPRO}/devkitARM
export PATH=$DEVKITARM/bin/:${PATH}

svn co http://proxmark3.googlecode.com/svn/trunk proxmark3-read-only
cd proxmark3-read-only
make

• Plug the Proxmark

./client/proxmark3

• Use it as Mifare emulator, https://code.google.com/p/proxmark3/wiki/Mifare

Flash the Proxmark using a BusPirate

• Get OpenOCD and compile it for the BusPirate

git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd
cd openocd
./configure --enable-buspirate --enable-maintainer-mode --disable-werror --disable-shared
make && sudo make install

• Wire the BusPirate to the Proxmark3
  • Pin 20 is GND and the the closest to the center of the board
  • Connect GND, TDO, TMS, TDI, TCK using these pinouts, respectively p3 and buspirate

wget https://raw.githubusercontent.com/hewittc/proxmark3lcd/master/tools/at91sam7s512-buspirate.cfg
openocd -f at91sam7s512-buspirate.cfg

• Connect the p3 by USB
