Problem with F28035

Hi everyone,

I just received my XDS100 and I am trying to make it work with my costum board but I always get this error:

C28xx: GEL Output: 

Device Calibration not complete, check if device is unlocked and recalibrate.C28xx: GEL Output: 

Device Calibration not complete, check if device is unlocked and recalibrate.C28xx: File Loader: Data verification failed at address 0x00008000 Please verify target memory and memory map.

Error found during data verification.

Ensure the linker command file matches the memory map.

I try 2 different chip (10$/chip is a lot of money for a student) and I can't get rid of this error. What should I do next and how can I confirm that the chip is locked.

Thanks

    When device cal runs from the debugger (via a .gel file) it requires that the code security module be unlocked.

    This wiki article describes how the code security module (CSM) can become locked or appear to be locked.  Since this is a custom board I would suggest first checking the flash voltage on the VDD3VFL pin.
