Hi Kiebach,


Could you describe the symptoms or any error messages? A few important points to consider:


  • If you’re using QSPI flash, ensure the serial or quad SPI flash reset pin is connected to the AS_nRST pin. The SDM must fully control the QSPI reset, so avoid connecting the quad SPI reset pin to any external host.
  • For AS x4 configuration mode, set AS_CLK to 166 MHz, and use a Micron QSPI flash memory device within the 2 Gb density range.


For further details, please refer to the configuration user guide: [https://cdrdv2.intel.com/v1/dl/getContent/813320?fileName=ug-ag-config-683673-813320.pdf].
