Set JTAG password lock SPC58EC80E5/AEK-MCU-C4MLIT1

Hello,

I'm working with the AEK-MCU-C4MLIT1 board, which features the SPC58EC80E5 MCU. While using UDE STK 5.2, I noticed that the JTAG connection is always successful, regardless of the password set to unlock it. This suggests that the JTAG password lock is not yet enabled.

What would I have to do to enable the JTAG password lock?

Thanks!
