7.3.6.3. Updating the Factory Image

The Update the Factory Image menu, Option 6 performs RSU Image update by updating to a new factory image and decision firmware version. Before initiating Option 6, you are recommended to run Option 7 to erase the current decision firmware to show that a new decision firmware is updated along with the factory image.

The operation begin by reading the Factory Update RPD image from the QSPI flash, starting from address 0x3800000. After the RPD image is read successfully, the software proceeds to add and verify the configuration bitstream into a temporary FactoryUpdate slot. Once it is completed, power cycle the device.

Note: After the factory image is updated completely, the device automatically reconfigure to the application image with the highest priority.
