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:

v1495test11) function
The v1495 library has the function below which when
//v1495test()
int
v1495test(unsigned int baseaddr)
{
// the address location below starts at the USER FPGA access location which is
//0x8000 lower in memory than the dial switches for the module address location.
// if SW3=0 SW4=8 SW7=1 SW8=1 => 0x80118000 is the 32 bit address and 0x90118000 is the 24 bit adresss
// then try v1495test(0x80110000)
volatile V1495 *v1495 = (V1495 *) baseaddr;
unsigned short *data16 = (unsigned short *)&(v1495->control);

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
for example the dial settings are
| Address | |
| Pin | Setting |
| SW 3 | 0 |
| SW 4 | 8 |
| SW 7 | 1 |
| SW 8 | 1 |
Instead of the address of the control register (which corresponds to the dial settings) You need to pass the memory address of the USER FPGA access which is 0x8000 lower in memory
for example
v1495firmware(0x80110000,"GEMReadout.rbf",0,0)
and NOT v1495firmware(0x80118000,"GEMReadout.rbf",0,0)
it took about 10 minutes to download
