If the debugging port is disabled, the program cannot be written. How to solve this problem？

As shown in the figure:

May I ask that the Debug was closed through PE configuration last time, but it cannot be burned in now, is there any solution?

Please refer the answer in: How to burn the program in KEA8 if SWD is disabled in main.

The easiest way is to use the P&E Multilnk (it can be a 'normal' one), with the PEMICRO Recovery utility, see https://mcuoneclipse.com/2021/05/20/recovering-cortex-m-microcontroller-with-a-power-glitch/ and https://mcuoneclipse.com/2013/06/16/bricking-and-recovering-frdm-kl25z-boards-reset-swd-clock-and-low-power/

For the above you need the PEMicro debug probe.

If you have a J-Link, then you can try the 'resurrect locked Kinetis device' in the MCUXpresso IDE, see

There is a command line way too, see https://mcuoneclipse.com/2014/10/05/unlocking-and-erasing-flash-with-segger-j-link/

I hope this helps,

Erich
