Intel Stratix 10 Configuration User Guide

You can now remove the current or new application image address image pointer
slot by writing the value to 0x00000000 using the qspi_write_one_word
function as shown in the following example. The qspi_write_one_word function
takes address and data arguments. Be sure to erase the application content that
you just removed from flash memory.
You can use a qspi_read to the image pointer slot at offset 0x28 for CBP0 and
CPB1 to verify completion of the qspi_write_one_word commands .
You can now configure the device with the old application image. The old
application image has the highest priority if you power cycle the device or the host
asserts the nCONFIG pin. You can run the rsu_status report to check the status
of the current image address, 0x002f4000.
