I'm recently facing this issue. The S32K116 Evaluation board (XS32K116EVB2Q048) is not able to get flashed with any new firmware .
I'm not able to bring it in debug neither through the external programmer (Using Multilink programmer), nor through the Open SDA debug port.
Kindly suggest if there is any way to recover it, as I think it has gone into secured state, but do not exactly know the reason .It was previously working fine. I only tried to power it up using external 5V power supply adapter. Not sure if that has anything to do with boards current situation .
