Hi all,

I am working on STM32F407ZET6 controller. I am facing problems after downloading code into the controller, it shows some error messages. When i download my code into the controller using J-Link and when i press on RUN icon in IAR Embedded work bench then it shows following errors:
1. Write to IR: Expected 0x1, got 0xf( TAP Command: 10)@ off 0x5. Session aborted.
Sometimes it gives me an error like,
2. Core is locked up, can not halt CPU

So can anyone please tell me what might be the reason of those errors and how can i solve that?

Thanks & Regards,
