Hot Attach

Important notes

Perform Hot Attach procedure

Perform Detach procedure




Hot Attach and Detach functionality allows you to attach (and detach) the BlueBox development system to a running target system without affecting its operation and have all debug functions available. As such, it is a very convenient troubleshooting tool when the application malfunctions after a longer time.




Fixed voltage based on the Target

Drive RESET while Detached configured to ''no''



Important notes

10-pin 1.27mm Infineon DAP2 Wide Debug Adapter (IC50163-2) and all Active Probes do not support Hot Attach in a sense of connecting to a live target with the cable. You need to attach the cable to the target before running the application.

Using any of the Download or Reset functionalities will in fact reset the microcontroller (whereas in older winIDEA versions Download has been ignored while in the Hot Attach state).

Hot Attach on RH850 is not possible with Mictor 38-pin Nexus debug & trace adapter. Use LPD debug connector for Hot Attach.

Hot Attach is not supported on MPC51xx devices.

Detach procedure can also be executed with or after Debug / Download.



Perform Hot Attach procedure

Target is powered and running. Your BlueBox is off and physically disconnected to the target.



Set fixed voltage based on the Target via Hardware / CPU Options / Hardware.

This might not be needed for some newer Active Probe adapters.




Set Drive RESET while Detached to ''no''  via Hardware / CPU Options / Reset.





Connect your BlueBox GND and the target GND using the grounding wire.



Power on your BlueBox.



Power on your Target.



Select Debug / Prepare to Attach

Wait for winIDEA-status-SoC-detached Debug Status.



Attach to the Target via Adapter or Active Probe.




Select Debug / Attach to establish debug connection with the microcontroller.



Perform Detach procedure

Debug session is active. Your target is powered and running, Debug Status shows winIDEA-status-RUN.



Disconnect debug session via Debug / Detach.

Debug Status will change to winIDEA-status-SoC-detached.



Disconnect Adapter or Active Probe from the Target.




Disconnect from the BlueBox via Debug / End Session.

Debug Status will change to: winIDEA-status-offline



Power off  the BlueBox.
