When I debug the CSEc of S32K144, I Use function FLASH_DRV_DEFlashPartition(&flashSSDConfig, 0x02u, 0x08u, 0x03u, false, true). then I Power down and Power up my device.
Now, I can't connect my device via P&E or OpenSDA or J-link.
The S32DS tip me: ”Device is secure,Erase to unsecure“, but I can't Erase my device. S32DS tip me this twice, then S32DS show a disconnect UI to me.
How can I reuse my device via debug tools?
Hi,
you can try Emergency Kinetis device Recovery in debug session settings:

Hi, Jiri
Thanks for my question.
I have three devices can't be Erased.I tried this method, it is effective on one device. but other two devices have no effect.
I also tried other method. I refer to thread1, thread2 and document. I also use script "erase_all_pin.jlk" with j-link.
but I can't erase my other two devices.
I used "unlock kinetis" command, It tips me O.K. but I can't connect my device with J-link or OpenSDA or P&E.
I used the script "erase_all_pin.jlk", it tips me so many "Protection tip".
At last it tips me a "Cannot connect to target".
There is any other method to reuse my devices?
Thanks a lot.
Hi,
your device has probably also disabled mass erase. With this settings there is no way back (device is secured, mass erase disabled). and only soldering iron can solve it.

Hi, Jiri
If so, that would be sad.
But,whatever, thank you very much!
