BlueBox: I can no longer connect to the SoC

Sometimes the SoC can end up in an unrecoverable state after the debug session is established and operational. Neither performing the Download nor Reset command regains winIDEA control over the SoC

Possible solution

Try to restart the whole setup via a Power off/nn cycle. 

Considering the system is powered, perform the power cycle in the following order:

1. Turn off the target.
2. Turn off the BlueBox.
3. Wait a second.
4. Turn on the BlueBox.
5. Turn on the target.
6. Execute Debug > Reset.
