CCS/TMS320F28335: DSP/BIOS Run Time Analysis without RTDX

Part Number: TMS320F28335


Tool/software: Code Composer Studio

I need to check CPU loading but my emulator does not support RTDX.  Here are my particulars:

Code Composer 6.0.0.00190
DSP/BIOS 5.42.1.09
Windows 7
XDS100v2 JTAG emulator.

I know CCS6 doesn't support DSP/BIOS, so I tried loading CCS5.  I then found out my emulator doesn't support RTDX.  So I would like to do this programmatically on the target system.  I can enable RTA in the configuration script, and have some access to the objects, but I have a few questions.

The DSP/BIOS Users Guide has good information on how to calculate CPU loading, but it doesn't say how to get the "idle loop instruction count", which is calculated in BIOS_init().  Is this number accessible from my program?

Is there any way my program can access the system log contents?

Is there an alternative for RTDX?
