Why Is an Error Received While Downloading to the Target PC,
but the Host PC Indicates a Successful Download?
If you boot up a target PC with a boot disk or image from a previous release,
then build and download a target application from a host PC running a later
release of the xPC Target software, the host PC might indicate a successful
download. H ow ev er, the target PC might d isplay an error messag e like the
following:
rt_init timing engine not found
This is because the xPC Target software on the boot disk or in the boot image
did not match the version of xPC Target software running on the host PC.
As a general rule, you must always create a new boot disk or image with a
new xPC Target release or upgrade.
To resolve t his, create a new boot disk or image, using the host PC xPC Target
software, and reboot the target PC with the new boot disk or image.
Note You should properly label and store old boot disks in case you need to
use them a gain.
