Rsu Recovery From Corrupted Images - Intel Agilex Configuration User Manual

Reconfiguration includes the following steps:
1. After the device exits power-on-reset (POR), the boot ROM loads flash memory from one of the four static firmware slots
at addresses 0, 512k, 1024, or 1536 to initialize the SDM. The same configuration firmware is present in each of these
locations. ( Refer to Step 2 of
step-by-step details for programming the firmware into the flash.)
2. The optional direct-to-factory pin controls whether the SDM firmware loads the factory or application image. You can
assign the direct-to-factory input to any unused SDM pin. The SDM loads the application image if you do not assign this
pin.
3. The configuration firmware pointer block in the flash device maintains a list of pointers to the application images.
4. When loading an application image, the SDM traverses the pointer block in reverse order. The SDM loads the highest
priority image. When image loading completes, the device enters user mode.
5. If loading the newest (highest priority) image is unsuccessful, the SDM tries the next application image from the list. If
none of the application loads successfully, the SDM loads the factory image.
6. If loading the factory image fails, you can recover by reprogramming the Quad SPI flash with the RSU image using the
JTAG interface.
