I am working on SPC563M64 controller. I have started working on shadow flash now. But during testing of shadow flash code I got debug port fail error while trying to connect to controller. I think the board is permanently reset and I am not able to connect to my board again. What can I do ? I have also tried the sequence of commands in a sequence listed below but still I was not able to connect to controller :

1. system.option.cpu   

2.SYStem.Option.KEYCODE 0xFEEDFACECAFEBEEF

3. system.up.

Please tell me what is this issue is ?

    Hello Ankit ,

    You are using TRACE32 lautechbach ..

    Have you updated the shadow flash ?

    could you try to click on Reset Button of your board in trying to connect the debugger in the same time .

    Maybe , there is a sort of reset escalation.

         Best Regards

    Yes I updated shadow flash and after that I did reset and from then this problem is coming.

    I tried to connect to board while press the reset button at the same time but error showed that ' target reset failed '.
