8451 "timeout expired before operation completed"

[EricS.]

Hey Mike,

I just spoke with R&D again this morning and forwarded on the spy capture and information you included.  They're going to look into this, and I'll keep you posted.  Thanks!

I have experienced the same problem.  In my case it often (but not always) occurs when the device with the I2C chip is not connected and the SDA and SCL lines are floating.  Has there been any new information on this?

A firmware upgrade corrected the issue I was having.You will need to contact NI and ask them for it.

It was a very great story!!

Could you please let us know what firmware version is no problem that abnormally timeout is stopped?

Could you please let us know how we do upgrade the firmware version for NI845x?

Thanks,

SW
