Partial reconfiguration

[savmil]

Hello,

i'm trying to write frame for reconfigure my fpga on the fly.

I have tested this design: i have an icap interface that read for me a frame and store it in flash, after when i press a button i read that frame from flash and i write it in the fpga, but i found a series of command that when icap execute it, i see a strange behaviour.

When i write the frame, i see that not change only the frame that i have written to fpga, but it returns to a state that is indicated when i read the frame.

There is a way to write a single frame on the fly, using icap?

Hello, savmil!

Could you please give me a more in depth explanation of your issue? What kind of strange behavior do you see? 

Best regards, Ovidiu

In my design i have a counter a register and the FSM that work with icap, when i read, i save only the state of register( frame where register is saved and i set manually place it far from other component), but when i write the frame not only i restore the state of register but also the counter and FSM return to the state when i read.

Thank in advance.

Sadly, I believe the Xilinx support team would be of more help. I am attaching a link for you in order to either find the documentation you need or support.
