winIDEA/BlueBox: Initial debug connection fails

The debug session cannot be established or it is unreliable.

Possible causes and solutions

Wrong BlueBox selected

Open Hardware | Debugger Hardware | Hardware Type and select your BlueBox. 

Wrong CPU selected

• Check in Debug | Configure session | SoCs  if the correct Device is selected.
• Create a New Workspace

Wrong Debug Adapter used

Check if you are using the correct Debug Adapter for your target. 

Debugger connected to the wrong target connector

Check if the debugger is connected to the correct target debug connector.  Multiple target connectors can have the same physical appearance and size but have different functionality.

Wrong Debug Adapter orientation

Make sure that the pin 1 of the adapter is aligned with the pin 1 on the target.

Target is not powered

Check if the target is turned on and if the power supply is applied to the microcontroller. Use a volt-meter for confirmation (particularly on targets without visual indication of power supply presence).

Target is supplied with an incorrect voltage

The target must be supplied with the voltage in the range that is defined for it. Check the target reference manual for power supply specifications.

The cable connecting the debug tool and the target is damaged

Inspect the cable for any physical damage. If possible, check the connections with the ohm-meter. If it is damaged, contact  Technical support for a replacement.
