Linux and Chipscope

Hey guys,

 

I just discovered I could run Linux and Chipscope (JTAG) at the same time ( I have been doing this on the ZC706 so far).

 

This is a great feature because you actually debug the real design, this is no longer simulation.

 

Here is an example:
program some registers (phase increment) from Linux, start a FSM, trigger on some signals.

 

I am not able to declare an interrupt while the logic analyzer is running: my guess is this device is using a hidden one so the FPGA-interrupt table is shifted by one. This means I cannot debug my IRQ handlers in this configuration.

I might be able to work it around in a near future.
