CCSv5 - DSP BIOS problem (OMAP138 Experimenter kit)

Hi
 
We are working with a Experimenter kit OMAP138 to evaluate if a c6748 fits our needs and we can substitute our older C6727 with them.
We have started a new CCSv5 project with our CCsv3 files and finally got it compiled and working loading and debugging our code through a XDS560 PCI emulator.
 
However we have a problem with DSP BIOS since we cannot see RTA graphs (CPU load and STS statistics). In CCsv3.3 it has always worked flawlessly.
We load our code, launch it, then RTA, then CPU Load but the CPU load screen is completely static with no refreshing data. The same for statistics.
 
In RTA we enable CPU Load / STS though it seems to be already enabled. But nothing different.
 
The TCF seems to be correct.. RTDX - JTAG is enabled, and everything seems equal to CCSv3.3. DSP BIOS config that worked.
 
We are just debugging this DSP BIOS since so far we are not using SWI or HWI tasks.
 
We have seen that there is a SYS BIOS for upgrading this DSP BIOS but we mean to keep DSP BIOS since we don't have enough time to migrate this.
 
Our CCSv5.1.0.09000 comes along DSP BIOS 5.41.11.38 which states a 6748/OMAP138 compatibility.
 
Any idea of what is going on??

    Adding some info:

    In DSP BIOS general, all 'enable RTA', 'use instrumented BIOS' and 'enable TRC..' are ticked.

    Otherwise I even cannot open CPU load window.

    If I tick them, I can open it, but as I said in previous post, there is no movement at all...

    Code performs some inits and then just one SWI call

    main(){

    initDSP();

    SWI_post (&fastTaskSWI);

    }

    CPU and statistiscs don't change at all while I should get a CPU around 100%.

    However 'Raw logs' actually moves:

    0,0,Unknown,TSK,TSK: ready TSK_idle (0x1183410c),RTASystem
    1,1,Unknown,SWI,SWI: post  fastTaskSWI (0x1183418c),RTASystem
    2,2,Unknown,SWI,SWI: begin fastTaskSWI (0x1183418c),RTASystem
