Possible recovery steps:
For QSPI operation: Check signal integrity of QSPI interfaces and attempt command again.
For HPS restart operation: Retry to send the command again.
C
HW_NOT_READY
Possible recovery steps:
For QSPI operation: Reconfigure the device via source. Ensure that IP used to build your design allows access to
the QSPI flash.
For RSU: Configure the device with RSU image.

QSPI_HW_ERROR
Check the QSPI interface signal integrity and to ensure the QSPI device is not damaged.
81
QSPI_ALREADY_OPEN

5.4. Quad SPI Flash Layout
5.4.1. High Level Flash Layout
5.4.1.1. Standard (non-RSU) Image Layout in Flash
In the standard (non-RSU) case, the flash contains four firmware images and the application image. To guard against possible
corruption, there are four redundant copies of the firmware. The firmware contains a pointer to the location of the application
image in flash.
