2.1.4.1. FPGA Reconfiguration May Cause Device to Halt

Description

During reconfiguration of the Agilex™ 7 FPGA device that performs a firmware reload, the device may halt if the following conditions are true:
  • Attestation or Black Key Provisioning (BKP) is enabled.
  • There are no clocks on TCK (JTAG clock) since the last reset.
For example, if you enable Attestation or BKP as well as tie TCK low through a pull-down resistor, as recommended in the Pin Connections Guidelines, the device may halt during the FPGA reconfiguration.

Workaround

To workaround for this issue:
  • You must use the Quartus® Prime Pro Edition software version 21.3 or later, which includes the required firmware for Attestation or BKP.
  • Do not connect the TCK pin to ground. You may leave the TCK pin unconnected.
    Note: The unconnected TCK pin does not affect the device functionality. Recommendation from Pin Connections Guidelines (not mandatory): Connect TCK pin through a 10kΩ pull-up resistor to the VCCIO_SDM supply, for additional noise suppression.
