Hi, is it possible to lock out debugger access after programming the DCF record in the UTEST memory region?

I am using the

SPC570S40E1 micro and the Lauterbach debugger. After programming a DCF record incorrectly, I am getting a 'debug port fail' error when entering these commands: �SYStem.DETECT CPU� or �SYStem.Up�.

How do I go about unlocking the device?

Thanks

Hello ,

you should configure your debugger to enter the password NVPWD1/NVPWD2

the default password is 0xFEED_FACE_CAFE_BEEF.

Best regards

Hey Erwan, I have tried the command '

SYStem.option.keycode 0xFEEDFACECAFEBEEF' , but it didn't work.
