Directories and files

# EDT driver install
/home/scexao/src/EDTpdv_lnx_5.5.5.1.run

# working directory (all commands executed from here)

# SDK install directory

Deps

Installation requires kernel sources:

sudo apt-get update
sudo apt-get install linux-source
sudo apt-get install linux-headers-generic

Installing EDT PDV software for Linux

Download the files from (https://edt.com/pdv_run_installation_instructions/). Right-click on the link, then select “Save link” from the drop-down menu.

Save the EDTpdv_lnx_5.5.5.1.run file to some temporary directory. Then change to that directory and run:

chmod +x EDTpdv_lnx_5.5.5.1.run
sudo ./EDTpdv_lnx_5.5.5.1.run

Select default install directory when prompted (/opt/EDTpdv). Install takes a couple of minutes.

Provisional bugfix

Note: Ubuntu 20.04, kernel 5.4.0, the install wouldn't work, failing at the module compilation and with a less than helpful error message telling to check if linux sources are installed. Checking the make log point to:

No rule to make target 'arch/x86/tools/relocs_32.c', needed by 'arch/x86/tools/relocs_32.o'.  Stop.

This can be fixed, going in /opt/EDTpdv/module/Makefile and amending (line 90):

$(MAKE) -C $(KDIR) V=1 SUBDIRS=$(CURDIR) modules # 1>make.output
into
$(MAKE) -C $(KDIR) M=$(shell pwd) V=1 SUBDIRS=$(CURDIR) modules # 1>make.output

The magic involved here is beyond me, but it worked. Complete the installation by running, /opt/EDTpdv:

sudo setup.sh

Post checks

After installation, the kernel module edt should be loaded. Command:

lsmod | grep edt

returns:

edt                   200773  0

The following device should also appear:

/dev/edt

Device configuration guide

If the kernel version changes

Changes in kernel version will prevent the kernel module edt.ko to be loaded. The driver will need to be re-installed and the kernel module rebuilt:

# run from /opt/EDTpdv/
sudo ./uninstall.sh

# re-install drivers and kernel module (see previous section)

Alternatively:

# Navigate to /opt/EDTpdv
make unload
make driver load

Hardware Initialization of Camera

/opt/EDTpdv/initcam -c 0 -f config/cred2_FGSetup_14bit.cfg 

Application program

Running the camera requires running two process: server (ircamserver) and image acquisition (imgtake).

Compile

Application programs are ircamserver and imgtake. To compile:

cd ./src
./compile
