1.1.2.1. False Configuration Failure in Active Serial Multi-Device Configurations

Description

In Active Serial (AS) multi-device configuration mode, the error checking for CONF_DONE release may not operate correctly. As a result, you may experience false configuration errors. The failure is indicated by the CONF_DONE going high, followed by the nSTATUS going low and reconfiguration repeatedly initiated.

Workaround

To resolve this issue, perform both of the following:

  1. Disable the CONF_DONE error checking in AS multi-device configuration mode:
    1. If you are using Quartus II software version 12.0 or older, check the “Disable AS mode CONF_DONE error check” option. This option can be found in the “Advanced” button, under the Convert Programming File window.
    2. If you are using Quartus II version 12.0 SP1 or later, the error checking is disabled automatically for AS multi-device configuration POF file generation.
  2. Enable the INIT_DONE pin option:
    1. To ensure a successful configuration, Altera recommends that you enable the INIT_DONE optional pin for devices in the configuration chain. On the board, route out the INIT_DONE pin separately for both the master and slave devices. Monitor the INIT_DONE status for each of the devices to ensure a successful transition into User-mode.
Note: Other configuration modes (JTAG, Fast Passive Parallel (FPP), and Passive Serial (PS) (single and multi device configurations, and AS single-device configurations) are not affected.
