Regaining debug after reconfiguration of SWD pins

Discussion created by adrianraileanu Employee on Mar 30, 2017

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)
