Hello i´m working with the FRDM-K32L3A6 Freedom Development Board,
i just wanted to use some GPIO Pins but i´ve inadverently programmed J7[6] and J7[4] as GPIO Input/Outputs, now i´m unable to flash the board again. I´ve set everything back like it was before, tried to flash the hello world example, tried to use the gui flash tool, made an mass erase, activate sysresreq. Nothing helps there´s always this error message:

What can i do to reset the board and to flash it again. I think theres a problem because these pins are something for SWD.
Thanks for you´re help.
