winIDEA HelpHot Attach
In this topic:
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.
Debug I/O levels
|
When using Hot Attach, Debug I/O levels should always be set to fixed voltage based on target I/O voltage level in the Hardware menu / CPU Options / Hardware! (This might not be needed for some newer Active Probe adapters.) |
|
Drive RESET while Detached
|
When using Hot Attach, Drive RESET while Detached should be configured to ''no'' in the Hardware menu / CPU Options / Reset. |

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. |
Hot Attach procedure
|
Target is powered and running. |
Your BlueBox is off and physically disconnected to the target.
|
Connect your BlueBox. |
Connect your BlueBox GND and the target GND using the grounding wire delivered with the BlueBox.
|
Power on your BlueBox. |
Follow the steps of the Power On/Off procedure.
|
Prepare to Attach. |
Select Debug / Prepare to Attach and wait for 
status in winIDEA.
|
Attach to the target. |
Now you can safely attach the Debug Adapter or Active Probe to your target. An example of hot-attaching a Debug Adapter to the target.

|
|
Hot Attach. |
Once connected, select Debug / Attach to establish debug connection with the microcontroller.
|
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
|
This procedure can also be executed with or after Debug / Download. |
|
Debug session is active. |
Your target is powered and running, winIDEA status shows: 
|
Disconnect debug session via Debug / Detach. |
winIDEA status will change to
|
Disconnect Debug Adapter from target. |
|
Disconnect from Debugger via Debug / End Session. |
winIDEA status will change to: 
|
Power off the Debugger. |
