RTOS-EPOC Technical Information Technical RTOS Debugger for Symbian OS (EKA1) ■ Real-time non-intrusive display of SymbianOS system resources ■ Symbian OS specific display of trace listing ■ Statistic evaluation and graphic display of thread run times ■ Thread related evaluation of function run times ■ Statistic evaluation and graphic display of thread states ARM ■ Thread stack coverage ■ Thread context display ■ PRACTICE functions for OS data ■ Symbian OS related pull-down menu The TRACE32 System includes a configurable RTOS debugger to provide symbolic debugging in real time oper- ating systems.Our software package contains a ready-to- run configuration for the Symbian OS Real Time Kernel (formerly called EPOC) from Symbian. In close cooperation with Symbian, we built a highly sophisticated Symbian OS awareness, which enables you to do a most effective debugging with the TRACE32 sys- tems on targets running Symbian OS.
