MKV31F128VLL10 sawtooth on reset pin

Hi, this if my first project with Kinetis, and I'm seeing a saw tooth waveform on the reset pin after a power up. I can connect to the target board and run/debug the application, however when I disconnect the probe (Jink) I see an oscillation on the reset_b pin.

First, I thought that this problem could be related to the fact that I was trying to use the NMI_b pin as GPIO. I changed the configuration on the board, so now the NMI_b is no longer a GPIO, but the problem still persists.

Any ideas what could be causing the problem or suggestions to fix it?

Any help appreciated. Thanks in advance.
