XC2V2000 + System Ace + Reconfig

[Joerg Ritter]

Hi,
we tried to reconfigure a VirtexII using the Xilinx Multimedia Demoboard.

The configuration can be done using CF-Card and System-ACE (bye the way,
how do you pronounce ACE, A-C-E ? ) or via JTAG.

The MPU port of the System-ACE is connected to the Virtex device.
We want to initiate a reconfiguration from the FPGA itself. In order to
do that, we send a byte to the CONTROLREG register of the System-ACE
using the MPU port.
In this way we set the FORCECFGMODE bit and the CFGSTART bit to 1 at the
same time.

Unfortunately the reconfiguration doesn't start.

Any ideas?


Thanks

Joerg

Joerg,
you might want to have a look at the c file at the following
location in your hard drive
<home Dir>:\EDK\sw\iplib\drivers\sysace_v_1_00_a\examples.
I used the low level config example to reconfigure the board.
Hope this helps
Ram
