Hello Andreas, The provided CTL program doesn't compile. It throws an error "action not allowed outside sequencer states". The action "GOTO level1" in line 3 is outside the state machine. You probably want to add another level. Additionally, you need a statement for selective data trace of the task switches. I'm not sure about your intention when using task_timer. The below CTL program should do the following: */ Trace all write access by core2 to the current task identifier of core2 "TASK.CONFIG(magic:2)". This statement is independent of the state machine. */ When arming the trace "level0" is the active state */ When core2 execute "sieve" entry "level1" becomes the active state. This state transition switches on the Program flow trace and reloads "task_timer" */ As long as "level1" is active "task_timer" keep counting for 200 milliseconds. */ When "task_timer" reach the limit of 200 milliseconds a transition of the state machine to "level2" occur. */ When "level2" state is active, the next execution of "sieve" exit by core2 will stop trace recording and stop the target. //----------------------------------------------------------------- CORE2:: IF Var.Write(TASK.CONFIG(magic:2)) TraceData level0: IF Program(ENTRY:sieve) GOTO level1 level1: IF STATE.ENTER() RELOAD task_timer TraceOn Program IF TRUE() ENABLE task_timer IF TIME(task_timer>=200000.us) GOTO level2 level2: IF Program(RETURN:sieve) TraceTrigger Break //----------------------------------------------------------------- Is this the behavior you want to implement? Or can you give more details? What TRACE32 software version are you using? You can obtain this using the command: PRINT VERSION.SOFTWARE() Regards, Houcem

Hello, sorry, the failing script is may fault. Made an untested change before sending it to you. The software version: 2023.02.000159199 I have two goals 1. Do performance trace on tasks on a core 2. Do performance trace on functions on a core but I want to limit the performance trace for functions only to run on specific functions. I am doing on-chip trace so I have limited memory (2MB). If I do a full program+data trace on a core the memory fills up in 2.5ms. I want to expand that beacuse I am only interested some functions but I would like to see all tasks. Tried your scripts but I also get "symbol not found" complaining on task.config(magic[2]). I have loaded the orti. Did I missed something else? Adding another variable works e.g. var.write() Thanks for your support. regards, Andreas
