NI-VISA 4.6.2 beta for MAC OS crashes on Snow Leopard 10.6.2

[Sali]

Hello, I am using MAC OS X 10.6.2 Snow Leopard and problems occured with NI-VISA 4.6.2 beta drivers. These drivers are for evaluation on Snow leopard. Unfortunately NI-VISA configuration tools crashes immediately after start. I would like to ask what is recomended to do to solve this problem to be possible to access serial interface with LabView on Snow leopard. My second question is when we can expect the stable NI-VISA drivers will be issued?

Thank you so much for your answear

Sali,

Can you check the version of your NI-VISA Configuration Utility?

If it's not 4.6.2, can you remove it and reinstall VISA? If you did an upgrade (say from 4.5 to 4.6.2) instead of a clean install, maybe the file did not get replaced properly.

In terms of official release date, we typically do not provide that to the public since it's subject to change without notice. When it does release, I'll announce it on the forum.

Song D, thank you for answear. I already updated VISA for lastest beta version 4.6.2 and that problem occurs on this betaversion. There is not possible to launch that configuration utility, becouse crashed directly after start... here is part of crashreport:

Process:         VisaConfig [1930]
Path:            /Applications/National Instruments/NI-VISA/NI-VISA Configuration.app/Contents/MacOS/VisaConfig
Identifier:      com.ni.framework.VisaConfig
Version:         4.6.2 (4.6.2b0)
Build Info:      VisaConfig-200000~0
Code Type:       X86 (Native)
Parent Process:  launchd [136]

Date/Time:       2009-12-11 22:10:42.629 +0100
OS Version:      Mac OS X 10.6.2 (10C540)

I tried to reinstal VISA but without any effect. The same occurs, when I try to access VISA from LabView...in that case LabViev crashes sudenly. I dont know how to solve this, becouse I need to access serial port with LabView, but with this seems  to be impossible. I will be very glad for any suggestion to solve this problem...

Sali,

I could not reproduce this behavior even on 10.6.2. Can you describe your upgrade history (both VISA and OS X) a little bit so I can try to reproduce it here?

Also, it seems that the crash is caused by some hardware interaction, since the crash happens both in visaconf and LabVIEW. Could you take a NI Spy capture of the entire process? Or does Spy crash as well?

Song D,

I will decribe briefly my upgrade history. Clear instalation of MAC OS Snow Leopard 10.6.1 and upgrade to latest version 10.6.2.NI-VISA tool was instaled together with labview 8.6, I dont remember the version.Configuration tool run on this version, but crashed after try to change something in Resouce editor. After connecting my device it was visible but not able to communicate. LabView didnt crashed, but only didnt comunicate. I am trying to comunicate with FTDI chip on virtual usb port, drivers are installed and virtuall port available. After that I found VISA 4.6.2 beta drivers and tried to replace it. After upgrade Configuration tool crashes directly after launch, LabView crashes exactly at the moment when I am trying to asign visa resouce name (for example putting block Open VISA, than choosing Create - Constant (or control) and in that moment LabView crashes same as VISA configuration tool)

NI-Spy works, I tried to make several captures. Here is content of spylog:

1 - I am trying only to open VISA configuration tool:

1.  viOpenDefaultRM (0x19FFB170)
Process ID: 0x0000037A         Thread ID: 0xA07E5500
Start Time: 12:06:58.223

2 - I am trying to open .vi file which contains serial port communication on VISA:

 1.  viOpenDefaultRM (0x19FFB170)
Process ID: 0x0000037A         Thread ID: 0xA07E5500
Start Time: 12:06:58.223

3 - I am trying to create blank .vi file and crash occurs in the moment when I am asigning visa resouce name:

1.  viOpenDefaultRM (0x1B32B170)
Process ID: 0x000003A1         Thread ID: 0xA07E5500
Start Time: 12:14:06.068

I hope I found in the NI Spy all important information and that it will help
