[S32K144]How to restore the debug interface after it is disabled?

[Detective]

When using the S32DS software, I accidentally set the debug interface pin to be disabled, and then I cannot enter the debug or download the program through the interface. Is there any way to recover?

Thanks and waiting for your reply!

I can't connect to the MCU using USB Multilink, I may have disabled all the USB Multilink corresponding pins.

Hi,

You need to reset your board, try a few more times, it is possible in theory,
If not successful, you can only replace the new MCU.

Thank you, I have been using the USB Multilink download program, now the USB Multilink can not be connected, different from their openSDA situation, P&E recovery Utility's USB Multilink option can not recover, it seems that I have to replace the MCU,sad.
