Hi, 

 

I ran a simple program with two processes and got the trace logs from the emulator. The program is attached for reference. I ran it on 2 processors and emulated it on 2 processors. 

 

After using the loadlog tool to convert the logs to ascii the following message arises. 

 

Loading bgTrace ... 

========= BgLog Version: 6 ========= 

Found 2 (2x1x1:1w-1c) simulated procs on 2 real procs.

Loading bglog of proc 0 from bgTrace0 succeed. 

Proc 0 has 38 events. 

Error: Invalid log [0,#37]: startT: 0.006195 endT: -1.000000 execT: 0.000000

Loading bglog of proc 1 from bgTrace1 succeed. 

Proc 1 has 48 events. 

End of program

 

Why is there an error in the logs? 

 

Thank you 

Ashmita
