I used a BROM. I want to see it's output data at chipscope. but chipscope shows its last element only.
means I have a BRAOM of size 1200 data, where 1200th address contains data 255. then chipscope shows only data 255 and address 1200. it did not show data from 0 to 1200, which I want to see.
Another problem is BROM also have a reset signal. which i applied on hardware with a switch. Either I apply reset or not chipscope shows 255 and address 1200. but in simulation if reset is not applied then it does not show any data.
So, I want to ask where i mistaken.Please help me in this.

How you are accessing data from ROM? How you are connecting signals to chipscope?
It seems you have connected dout to probe in chipscope which is data of a particular address.
If possible share the code/project to have a look.

For a test I write a code which contains only dcm ip core, i used given code for that
input wire clk_p,clk_n,reset,
output wire clk1);
(// Clock in ports
.CLK_IN1_P(clk_p), // IN
.CLK_IN1_N(clk_n), // IN
// Clock out ports
.CLK_OUT1(clk1), // OUT 100 Mhz clk shown as a output on chipscope window
.CLK_OUT2(clk2), // OUT 200 Mhz clk apply as a chipscope clk
// Status and control signals
.LOCKED(locked)); // OUT
Here also either i apply reset or not it shows clk1 on chipscope.
I also attached my project files
