Hi,
I used BCM94390WCD2 platform to create a new project via WICED SDK 3.7.0 which contained the new OpenOCD release (v0.10.0-dev-00222-g43cdc13-dirty) in it.
When i executed the OpenOCD daemon, the OpenOCD returns an ERROR message - "Debug regions are unpowered, an unexpected reset might have happened" in the console and then try to reexamine it again.
I checked the ERROR in the detail debug messages, and found the "SSTICKYERR" bit has been set in the DP's CTRL/STAT register within "jtagdp_transaction_endcheck()" API. Changed the JTAG adapter speed did not help to fix this kind of error.
Is there anything we can do in "BCM439x.cfg" to remove such error messages?
Thanks for your help!
Following shows the full console logging messages:

Unfortunately at this moment in time the engineering core team has higher priority items on their list to resolve and this issue will be looked at as and when they have the resources. If any of our customers encounter this issue with this part in their development, they can always come back here and we will investigate them on a case by case.
