compile openocd release v0.1:
[extract to somewhere]
./configure --prefix=CHANGEMEtowhatever --enable-ft2232_libftdi
make
make install

to flash run from within board/pttu/tools:
./openocd-pttu.sh olimex-usb-jtag-tiny-a "mt_flash CHANGEME/absolute/path/to/hexfile/pttu.hex;shutdown"


to debug, first start the following from within board/pttu/tools:
./openocd-pttu.sh olimex-usb-jtag-tiny-a

then just run "jam debug". this will flash bin/pttu.hex, run it and stop at the bootloader.
