EGWU openocd.0.7.0 olimex jtag tiny

Rigged up the olimex JTAG tiny to plug into the 7 pin ARM-JTAG P8 connector. Same results. So this tells me there is a problem possibly with the lpc1778 chip or the JTAG pins. Once I buzz them out later tonight Ill have to seriously check for short and opens or consider that this chip may have been damaged during board assembly and to prepare to replace it ;(



sudo openocd -f interface/olimex-jtag-tiny.cfg -f board/egwu_board.cfg
