Troubleshooting
Linux
Try any of the following...
•
Failure during installation may be due to system package dependencies. Make sure the following packages are
installed on your system...
make
gcc
libtiff
linux kernel headers
For example
–
on Ubuntu, to install the
libtiff
library, enter...
sudo apt-get install libtiff4-dev
After all needed packages are in place, run
make
from the installation directory (see
) to
complete installation.
•
Uninstall and then reinstall your existing EDT installation package. To uninstall, use the programs in the installation
directory (see
),...
—
If the package was installed using
package
.run
, remove it with
./uninstall.sh.
—
If the package was installed using
rpm --install package,
remove it with
rpm --erase
package
.
•
Download and install the latest EDT installation package (see
NOTE
New Linux versions often require an updated device driver, so if you are using a new or updated Linux kernel and
you have trouble with the EDT installation or device access, check to see if a new EDT installation package is
available.
Corrupted Images, Slow Acquisition, Timeouts, Data Loss
Corrupted images, slow acquisition rates, repeated timeouts, or data loss usually indicate that the bus is too slow or the
driver is misconfigured. To correct this issue...
•
Verify that the camera configuration file is the correct one for your camera and operating mode; see
•
Verify that the EDT board is in a PCIe slot that is wired electrically (not just physically) to support the number of
lanes provided by the board. For example, a four-lane board requires a slot that has four or more lanes. Also, note
that some motherboards will
“split”
lanes between two slots, so that two x8 slots will become x4 if both are occupied.
•
Determine the bandwidth required by your camera, and then ensure that both the board and the host can sustain
the required throughput. For fastest full-mode cameras, your frame grabber and your host bus both must support
eight lanes. For multiple camera installations, the combined data rates should not exceed that of the board(s) in-
stalled.
•
Verify that the firmware file you loaded is the correct one for your camera and your mode of operation (base, me-
dium, or full mode); see
Firmware: FPGA Configuration (.bit) Files on page 22
•
Eliminate other devices, if any, that may be reducing the available bus bandwidth.
•
to verify that your setup meets bus and throughput requirements.
•
When updating to a new device driver, always recompile and relink applications that use EDT libraries (see
ware: FPGA Configuration (.bit) Files on page 22
