Hi Experts,
I am trying to connect a third-party JTAG Debugger(Yokogawa Digital Computer adviceLUNA) to Juno-r1 Board.
When using the firmware provided from Recovery-CD, the debugger is connected to Juno.But when using the firmware builded 15.12 LSK with DEBUG options,I can't connect in spite of same procedure and environment.
According to a error message showed by the debugger, the debugger fails to access to the Mem-AP's TAR register.
What should I confirm to connect adviceLUNA to Juno-r1 Board?
Best regards.
Hi,
Ah, my bad, I thought you were using a 3rd party JTAG in conjunction with DS-5. I'm afraid I'm not sure what the problem could be then. It's very strange that you're able to connect using the recovery CD, but not even able to connect during UEFI when using the latest deliverables.
Do you have access to a DS-5 installation and a DSTREAM? It would be interesting to see if the same issues are replicated using these tools instead.
Other than that, I really don't know what the issue is. The fact that it works with the recovery CD suggests it's not a hardware problem, but rather a software problem. But, we're not aware of anyone having these issues, at least when using DS-5 with a DSTREAM.
It might be worth contacting the distributor of your debugger (YDC?) to see if they're aware of any similar issues, or to see if they're able to replicate the issue using a Juno with the latest deliverables.
Also, you could try the inverse of what I suggested last time, and try to connect to Core0 of the A53 cluster?
