Re: [partial-reconfig] Partial reconfiguration with the ICAP
Hi,
In the problem I discribe using the LEDs I reconfigure via JTAG (not the ICAP). I have been thinking that the interuption of the flashing might have something to do with the boundary scan methode which I use, because the boundary scan is normaly intended to test a design. In these test the PCB and the fpga are decoupled and the fpga can be driven independantly of the pcb. It might be something like this that causes the interuption. In that case it is not a problem because the ICAP does not use the boundary scan methode. I've got to look deaper into this. An other odd thing is that sometimes when I download the bitstream the flashing of the leds stops permanently, the hole system crashes. Have you evver encountered something like this?
I have also thought of a pure software problem and was planning to look into this this week.
Thank you,
Karel
