The ZIP file below contains the HDL source code to download into the V1495

The ZIP file below contains the ROC library

ROC lib
compile library
To compile the ROC library I executed the following command within the subdirectory containing the v1495.c file
ccppc -fno-builtin -fno-for-scope -fstrength-reduce -mlongcall -mcpu=604 -DCPU=PPC604 -DVXWORKS -D_GNU_TOOL -DVXWORKSPPC -I/usr/local/coda/2.5/common/include/ -I../h -c -o v1495Lib.o -i v1495.c
load library onto the ROC
I then copies the library v1495Lib.o into my ROC library subdirectory which is where the ROC is pooing at boot up
/home/daq/CODA/ROClibs/libs
I loaded the library by hand by typing the following at the ROC console
-> ld < v1495Lib.o value = 268430512 = 0xfffecb0
Setting address
The address pins on this module are not labeled so I adopted the convention of numbering them from left to right as I look from the front pannel.
| Address | |
| Pin | Setting |
| SW 3 | 0 |
| SW 4 | 8 |
| SW 7 | 1 |
| SW 8 | 1 |
probing memory
I set the switches as follows
sw3 sw4 sw7 sw8
0 8 1 1
And the following is a printout of my board:

Download Firmware
To download the firmware to the USER FPGA area you need to pass the address which is 0x8000 below what the dial setting are
v1495firmware(0x90118000,"GEMReadout.rbf",0,0)
