Realtime PXI KERNEL error

[Flexrob]

I'm working with a PXI based on a NI 8176 embedded controller as a realtime platform.

Lately switching the controller on with the PXI boot disk, as often as not, yields the following error:

Fatal error KERNEL.146040: NoWaitHost specified but no application present!
No host debug possible.

Fatal error KERNEL.146080: System halted.
ETS Monitor halting with error code 2.

and the system halts. Then, after three or more reboots the system starts properly.

What is the meaning of this error?

Is it a software or an hardware failure?

What should I do to fix this bug?

Thank you very much,

These kind o f errors seem to be related to software problems.

What I recommend is:

1- if you are able to boot the system (from what you said it takes a while but eventually succeeds) then target to it from the Host PC via FTP (ftp://[ipaddress]/) and delete everything you possibly can from the /ni-rt folder. Also in the root folder delete these files:

- hdmon.bin

- ph_exec.exe

- ni-rt.ini

2- If you are not able to boot the RT system, you should create the Format HD disk from MAX to clean up the system

After this has been done, try and reboot the PXI system, reconfigure it through MAX and download the software again onto it.

If the error is coming up again, try and recreate a new PXI Boot Floppy, it might be corrupt.

Let me know about any further issue.

Unfortunately it was not a software problem.

A strange behaviour and an error message a little bit difficult to understand, however a few weeks after this problem arose the PXI controller had more serious problems: it did not boot up neither in realtime nor in windows.

The problem: the BIOS battery was dead. Now, with a new battery the system works both in windows and realtime.
