Agilex 7 boot from config flash over JTAG

Hello. I'm trying to do remote programming/rebooting of an FPGA's flash config.

After I've programmed the flash chip via the standard Quartus Programming, does the FPGA automatically load and run this bitstream (truly reading from the flash chip)?

Or is there a "Boot from Configuration Memory Device" JTAG function I can induce?

    HI sittinhawk,
     

    After you program the QSPI flash, the FPGA does not immediately run that image. It will load from flash only at power‑on or when you reconfigure, and only if MSEL is set to an Active Serial (AS) mode.

     

    To trigger it now over JTAG, you have a few options:

    If you need remote, image‑selectable reboot and rollback, use Remote System Update (RSU) on Agilex 7.

    Please refer to Agilex™ 7 Configuration User Guide 

    Regards,
