winIDEA HelpHot Attach
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.
Settings
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 tab. |

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 is not supported on MPC51xx devices. |
Detach procedure
|
This procedure can also be executed with after Debug / Download. |
|
Debug session is active. |
Your target is powered and running, winIDEA status shows: 
|
Disconnect debug session. |
