Instructions for installing pXar:

- follow: https://twiki.cern.ch/twiki/bin/viewauth/CMS/Pxar

Problems might occur with the DTB software:

check your SW version and if its different from the FW:

The flash files are at https://github.com/psi46/pixel-dtb-firmware/tree/master/FLASH

To be explicit, you could do the following, from within your local pxar directory:

cd .. git clone git@githubNOSPAMPLEASE.com:psi46/pixel-dtb-firmware.git

cd pxar/main

../bin/pXar -f ../../pixel-dtb-firmware/FLASH/FLASHFILE

FLASHFILE is your version needed:
Push it onto the DTB with:

../bin/pXar -f ../../pixel-dtb-firmware/FLASH/FLASHFILE

where FLASHFILE should be dtb_v4.6.flash. The download will take a while. Follow the instructions at the end: Wait until all 4 LEDs turn off and power-cycle the DTB.

To Run you need a config file:

../main/mkConfig -h

will show you the options and usage.

Then:

cd ../bin

./pXar -d YOURPATH -g

opens the GUI

If you have no connection to the DTB:

maybe your USB port is not configured:

execute:

# D. Pitzl. 2011
# init USB for psi46 test board
#
sudo mount --bind /dev/bus /proc/bus
sudo ln -s /sys/kernel/debug/usb/devices /proc/bus/usb/devices

sudo chmod 666 /proc/bus/usb/00*/*

# remove modules from kernel:
#old trivial:
# sudo /sbin/rmmod ftdi_sio usbserial
# intelligent:
# modprobe -c lists kernel config
sudo modprobe -r ftdi_sio
#sudo modprobe -r usbserial
