How to calculate the CPU load when an OS is used?
|
| |
| Ref: 0486 |
|
The CPU load is the percentage of time the CPU wasn't in the idle loop.
The command
Trace.PROfileChart.TASK
gives such a percentage view. You just have to identify the "idle" task(s).
1. Create a task group for this task with merge or hide option:
GROUP.CreateTASK "idle" "my_idle_task" /MERGE
2. If the chart should not distinguish between the other tasks you may also merge them:
GROUP.COLOR "other" MAROON
GROUP.MERGE "other"
An OS awareness has to be loaded.

The error message "PPCSIM Trap <number>" appears when using the OS awareness.
|
| |
| Ref: 0425 |
|
This error message is due to an incompatibility between the TRACE32 software and the loaded OS awareness.

Where do I get updates of the awareness?
|
| |
| Ref: 0251 |
|
The TRACE32 software releases available for download on the Lauterbach web site contain all latest RTOS awareness files.
For intermediate update please contact support@lauterbach.com.

Why does all RTOS menus/commands report: 'Sorry: Couldn't get symbol addresses'?
|
| |
| Ref: 0249 |
|
The debugger didn't find the symbol information of the RTOS.
Check, if the kernel is compiled with debug information, and if the kernel symbols are loaded and accessible.
