Device is secure

[emma_zhouhui]

I have a Board with S12ZVL MCU embedded in it.when I try to debug a project and use U-Multilink .I'm getting this error "Device is secure .Erase to unsecure" 

How do I solve this issue?

Hello Hui,

This issue is related to the connection of BDM interface, I can pick up some possible issue:

- The power supply should be 12 V

- Check the orientation of the BDM connector

- Check if the BDM cable is not damaged

- Check if the MCU warms up (If yes, it can be damaged)

- Do you have connected more than one BDM interface?

- You can try to use different USB PORT

I hope it helps.

Best Regards,

Diana

Please make sure your MCU is powered, as well check if you didn't reverse BDM connector, check BDM cable.
