TIpcieUS

initial setting after installing card into new machine

Login as clasrun and run command ti_config, enter root password in a process. It will save TIpcieUS's driver config file to /root directory. Later in case of problems, driver can be effectively restored by running script ti_reload.

It should be 3 scripts in $CODA/src/scripts directory with following contents:

ti_config:

#!/bin/csh
#
# save TIpcieUS driver config file into /root
#
set temp = `lspci | awk -F' ' '/9038/{print $1}'`
echo $temp
set dest = "/sys/bus/pci/devices/0000:$temp"
echo $dest/config
echo "Enter root password"
su - root -c "cp $dest/config /root/config"

ti_reload:

#!/bin/csh
#
# TIpcieUS driver reload
#
set temp = `lspci | awk -F' ' '/9038/{print $1}'`
echo $temp
set dest = "/sys/bus/pci/devices/0000:$temp"
echo $dest
echo "Enter root password"
su - root -c "cp -f /root/config $dest"

ti_menu:

#!/usr/bin/tcsh
#
# William's menu
#
~jgu/PCIeTI/TIpcieUS/tools/TIcontrol /dev/xdma0_user

Installing driver on newly built machine

ssh boiarino@...

For release 1.4.0 on RHEL7 mchines:

cd /usr/clas12/release/1.4.0/coda/src/TIpcieUS/xdma

For release 2.0.0:

cd /usr/clas12/release/2.0.0/coda/src/TIpcieUS-devel/xdma

make -B

Become superuser (su) and run following:

make install
reboot

NOTE: controlling tool can be used as following:

ssh as root

Run TI control script:

cd ~jgu/PCIeTI/TIpcieUS/tools
./TIcontrol   /dev/xdma0_user

or run following if exists:

/root/ti_init

For slave mode, type '2', then type '9'. It should bring TIpcie board to the right state. After that you can start the daq from scratch.

For Sampa setup, set TI board to the 'bridge' mode by typing '15'.

Another useful option is 4 - it shows temperature etc parameters.

Manual for TI board in PCI format in (pdf)

On some DELL servers (R440 for example) booter will give an pci error and ask to push F1. To disable F1 pushing, in BIOS go to 'System BIOS Settings' -> 'Miscellaneous Settings' -> 'F1/F2 Prompt on Error' and click 'Disabled'.

Sometimes device /dev/TIpcie may be removed during patching or/and rebooting process. To restore it do following as root:

cd $CODA/src/TIpcie/linux_driver
./reload_driver.sh
