Cannot detect a valid UIA session

John Conover

Hi,

I'm trying to use a Spectrum Digital OMAP-L137 eval board to get the DSP to run some older code to capture some metrics. I have added sys/bios logging and logging in my defaults configuration. But when I am running and open a Tools->System Analyzer, I get the following error:

Here is my setup:

Code Composer Studio Version: 5.1.0.09000

XDCtools 3.23.00.32

SYS BIOS 6.33.1.25

IPC 1.23.5.40

NDK 2.20.6.35

NDK Network Support 1.10.0.03

XDAIS 7.21.1.07

Any help or examples would be greatly appreciated.

Thanks,

John C.

Let me add to this that what I really need is to get execution times for a couple functions. I thought the RTA would give this to me but it is not working well as the only thing that looks semi-normal is the Exec Graph, and even that does not seem to show all the tasks running when I know they are. So would would it be better for me to try Events or maybe just going directly to the hardware counter registers in the DSP?

Thanks,

So I decided to use the XDC modules Timestamp_ calls. My question now is about the timestamps rollover. I use the Timestamp_get32() function and calculate the different in clock ticks:

                            time1 = Timestamp_get32();
                            MyFuction();
                           time2 = Timestamp_get32();
                           Timestamp_getFreq(&freq1);
                           delta = time2 - time1;

I'm currently getting delta counts around 0x2774b72e and a clock freq of 0x11e1a300. This would suggest the function is taking over two seconds, but how does the Timestamp modules account for rollover?

Thanks,
