Agilex 5 configuration via Avalon-ST x8 issues

I have a MAX10 device controlling the configuration of an Agilex 5 device (A5EC065BB23AI4S) set for Avalon-ST x8.   We use the MAX10 to translate serial programming from our processor to AvalonST x8 for the Agilex 5.

I am able to program both the MAX10 and Agilex 5 device via JTAG and verify we can talk to these devices via SPI busses in the hardware.

For the configuration via the MAX10 we bring nCONFIG low and nSTATUS returns from the Agilex 5 low.  We next bring nCONFIG back high and nSTATUS returns to high.  We start the Avalon-St transfer but never see INIT_DONE go high.  The odd thing is we also never see CONF_DONE go low even with nCONFIG low?    Any idea what else to check?  Below is a pic of the SDM_IO connections from the Agilex5 to the MAX10.
