firmware upgrade procedure from Bryan Moffit April 2013

1. Copy /root/linuxvme directory tree from pcal0 (or wherever it installed already).
   scp -r root@pcal0:linuxvme/ .

2. Copy /root/.bashrc (to set LINUXVME_* env variables)
   scp root@pcal0:.bashrc .
 
3. (re)Compile required libraries
   cd linuxvme/jvme
   make clean;make
   cd ~/linuxvme/ti
   make clean; make ARCH=Linux; make ARCH=Linux tiEMload
   cd ~/linuxvme/fadcV2
   make clean; make ARCH=Linux
   cd firmware/linux
   make clean; make firmwareGTest

4.  Update TI firmware
   cd ~/linuxvme/ti
   ./tiEMload ti132.svf

5.  Update fADC250 firmware (all in crate)
   cd ~/linuxvme/fadcV2/firmware/linux
   ./firmwareGTest 1 ../CTRL_FPGA_V2_TOP_0x0211.mcs
   ./firmwareGTest 2 ../FADC250_V2_TOP_0x0907.mcs

TI firmware can be found in coda.jlab.org, going to 'custom hardware, then TI, then firmware.

Test results - pulser with realistic shape

• FADC250 Signal: one channel - 100 events; width because of trigger jitter ?

• FADC250 Signal: one channel - one event

fadc250.SB.onepeak.pdf ( pdf)

• FADC250 Signals, offset=3300 for all channels: 16 channels - one event. Note: channel 6 - dead, channel 15 - overflow due to high offset

• FADC250 Signals, offset=3200 for all channels: 16 channels - one event. Note: channel 6 - dead
