S32K3 jtag locked

[huangjia]

Hi,

    My s32k344 seems been locked, i can not connect the core via jlink now. The reset pin output low pulse signal after power-up, and i tried to unlock it via JLINK commander, but it timed out.

   I post the reset signal and JLINK timed out picture below, and how to unlock the jtag?reset pulsetimeout while unlock

I solved it, it wasn't caused by jtag locking, it may be related with wdt.

    Hello, can you use JLINK to connect S32K3? How do you solve the WDT problem you mentioned? Could you please ask me！Thank you very much  ！

Sorry to response so late, i changed to PEmicro from Jlink, it seems unstable now on s32k3 platform.
