How do I perform channel reconfiguration if the error port on the ALTGX_RECONFIG megafunction is enabled in Cyclone IV GX devices?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to a problem in the Quartus® II software versions 10.0 SP1 and earlier, you may be unable to perform channel reconfiguration if the error port on the ALTGX_RECONFIG megafunction is enabled in Cyclone® IV GX devices. When this problem occurs, when the write_all port is asserted and the reconfig_address is set to 0, the error port is asserted and the channel_reconfig_done port is asserted for only one clock cycle.

A patch is available to fix this problem for the Quartus II software versions 10.0 and 10.0 SP1. Download and install the patch from the appropriate link below.


This problem is scheduled to be fixed in a future version of the Quartus II software.
