Intel Agilex Series User Manual

You can now remove the current or new application image address image pointer entry 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.
Figure 87. Remove Application Image
% qspi_write_one_word 0x004A0028 0x00000000
% qspi_write_one_word 0x002ec028 0x004A8028
You can use a QSPI_read to the image pointer entry at offset 0x28 for CBP0 and CPB1 to verify completion of the
QSPI_write_one_word commands .
Figure 88. Verify the Writes
% qspi_read 0x004A0028 1
% qspi_read 0x004A8028 1
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.
