I just want to share a possible solution in case you have "bricked” an S32KxxxEVB by running a code that reconfigures the debug pins (SWD_CLK, SWD_DIO) to other functions.
All you need is an external probe - P&E Multilink and the P&E Recover utility.
The procedure is the same as described for Kinetis devices in Erich Styger's blog:
Thanks to a customer for pointing to that solution.
(I've not tried it yet, I'll update when checking it on my own board)
Hello,
I am facing the same issue and unfortunately there is no P&E Multilink with me. Is there a way to do the same with Lauterbach debugger? Please share the steps if this is tried out.
Thanks

You can do it with other debugger too: Lauterbach, Segger Jlink.
If reset pin is also reconfigured, the point is to do repeated POR (eg. by using a jumper J107, J10), until the debuger gets to hold the core, before your code re-configures the pins.
Steps:
- set a debugger loop to reset and hold
- manually power on reset the board until the debugger gets to hold the core
