core timer blackfin

[ACarpio]

I need to use the core timer of BF-537. I am using the VIs for core timer included in service Palette, however, Whe I debug the program, I have two error messages :  "Write Byte: error reading data" and " ReadDWord: error reading data".  Only using the Open Timer VI the program hav error. I try to set the core timer via Inline C node and I have the same error. I make a dual debugging with the Visual DSP++ and I saw that TCNTL registe had a value of 0x0000000F so the timer already has enabled and working before to use the open vi or set via C routine. How can I solve this problem+ Is this a bug of the embedded module?

thanks

Hi Caribbean,

I see that you've spoken to someone here at NI to resolve this issue. You should be able to use the General Purpose timers for your application. Let me know if you have any trouble wtih the general purpose timers.

Hi Lion-o, well I have not problem using the gp timers, in fact I solved the issue using timer 1. However, the reason to choose BF-537 was because I  need to measure time in interval of 3 nsec more less and the core timer at 600Mhz os CCLK can do this. I received information about lv Blackfin team of the core timer is used by VDK, so I wondering why there VIs to control the core timer in LV Blackfin if it is used by VDK?
