Cotex-M7 : Is there any hang case which TCMwait could make?

kate mun

Hello,

I am using Cortex-M7 Processor and long latency memory with ITCM and DTCM

I knew that TCM protocol defines multi-cycles TCMWAIT signal (I read Cortex-M7 TRM).

So, I implemented ITCMWAIT and D#TCMWAIT.

Now, I have the serious problem.

          The problem is  that

          - while Cortex-M7 did well, in the specific case, it hang.

             In that case, I couldn't connect to Cortex-M7 with TRACE-32 and both ITCMWAIT and D#TCMWAIT had been HIGH

Thank you for your words.
