When testing my target I have a running application. After some time I want to download another application without resetting the target.

For that the Service Mode feature of UDE® could be used. Service mode is primary made for debugging applications by connecting to a already running target. Using the mode allows also to download applications without resetting the target. To enable the mode open menu Debug - Debug Server. Under the Download page please enable the Attach to Service Monitor option and enable the Download pattern option.

Now loading applications without reset is possible.

Please take into account that the program counter is now not set automatically to the entry point of the new loaded application. It has to set manually.
