Due to a problem in the SDM firmware released with the Intel® Quartus® Prime Pro Edition Software versions 20.1- 20.4, the RSU Notify feature may fail to operate correctly on Agliex. The user-defined the 16-bit HPC software state set prior to watchdog timeout may not be shown after the watchdog expires.
For more detailed information related to the RSU Notify feature, refer to Intel® Agilex® Hard Processor System Remote System Update User Guide.
This problem is resolved in the Intel® Quartus® Prime Pro Edition Software version 21.1.
