MPC5744P EVB Locked during programming

[davischen]

Hi  Daniel,

We have meet a stranged situation: Our EVB has been locked during programming with this operation of this chapter. 

I have attached the last screenshot,

and it cannot be programmed with other application anymore.

It seems this board has been secured. But I think I do not do any relative action.

However, I have do this with others and works well.

Do you have any idea about this?

Thanks, BR.

Hi davischen,

Did it happen after or during you have programmed the elf with RAppID bootloader?

Apparently, the microprocessor is dead or in a continuous reset - i do not think it is secured.

If you try to connect over the JTAG directly (not over the USB) can you connect with the device ?

Best regards,
Daniel

Hi Daniel,

Thanks for your reply.

Yes, it is. In the meantime, I also have tried cyclone-max to program it (with JTAG), and it cannot be programmed well anymore.

It seems I enable this lock feature during my opration.

But I just wonder how it happen...

BR.
