LabVIEW ARM break after update Front Panel during debug

[noom]

I try to debug the vi by Ulink, the vi just show the LED blinking for 500ms on/off with while infinity loop, after click run button the loop continue working about 5 second and then break button actived with front panel update. Is this normal working?

Thank you

Can you be more specific about "then break button actived with front panel update?"

[noom]

After I click Run button on the toolbar the vi start ranning, the LED blinking show on the hardware but not update to the vi front panel, around 3 second the vi stop (like a we click on Pause button on toolbar) and update the status LED to front panel.

I used ULINK1 for this example, I don't know this cause of the problem or not.

Thank you.

Does this occur with any other VIs, or just this specific one?  Is the time period consistent, or does it vary?  Can you confirm that you still have a good connection to the board after the VI stops?

[noom]

Yes, it occur on main vi any project. The time is consistent if I click on pause button again the vi will continue and after that 3 sec the vi will stop again. I confirmed I have good connection because I can download to the board, the debug working except the vi stop all the times(after stop I can click pause to continue).

I tried to open the Keil uVision3 project from the folder that generate from LabVIEW and run to debug mode(no LabVIEW running), I did not got any problem, the ulink run's led status showing. If I call Keil uVision3 from LabVIEW project and run in the same way, the debug mode will stop after 3 sec, the ulink run's led status show 3 sec also. This problem look like LabVIEW stop the debug process.

Thank You.

Which ARM board are you using, and which version of LabVIEW?

[noom]

Thank you for your response, MCB2300 board with ulink1, 60 day LabVIEW ARM v8.5.1. How many version of LabVIEW ARM?

Hi,

Do you have another computer you can try it on?  It could be a bad installation of LabVIEW, in which case you could try doing a repair installation.  You can do that from the Add/Remove Programs >> National Instruments Software in Control Panel.

Thanks, I will try to install to other computer. Can I have new LabVIEW ARM 1.1 evaluation to try and where I can download?
