Hi
i am trying to debug uTaskerv1.4.11 in codewarrior but everytime i try the debugging starts normal but a few steps in the it begins to say No source.
When i step over or into i just get new ones.
Here i the ones i get:
No source available for "0x080F0000 (0x080F0000)() "
No source available for "(AsmSection)() "
No source available for "0x48082010 (0x48082010)() "
No source available for "0x2E200B7A (0x2E200B7A)() "
I am not sure which source the are about.
i have attach two of them if that helps.
i am using a MCF5225 if that has anything to do with this.

Hi
This is probably the watchdog.
When debugging make sure that you disable the watchdog otherwise it will reset the device after a few seconds when stepping code and cause strange things to happen with the debugger.
Check the macro for your target (in app_hw_kinetis.h)
eg.
#define WATCHDOG_DISABLE() (!_READ_PORT_MASK(E, SWITCH_2)) // pull this input down to disable watchdog (hold switch 2 at reset)
There is usually an input that can be help in a particular state to disable the watchdog when debugging. Otherwise set to 1 so that it is always disabled.
Be careful if you use a device with backup watchdog timer [#define BACKUP_WATCHDOG_TIMER] (rather than core watchdog) since this watchdog continues to run after a reset. To stop it after it has once been configured a power cycle is required.
