for no errors.
7 Error details Stores the error details for the failing image. Returns 0 if

8 Current image retry
counter
Count of the number of retries that have been attempted
for the current image. The counter is 0 initially. The
counter is set to 1 after the first retry, then 2 after a
second retry.
Specify the maximum number of retries in your Intel
Quartus Prime Settings File (.qsf). The command is:
set_global_assignment -name
RSU_MAX_RETRY_COUNT 3. Valid values for the
MAX_RETRY counter are 1-3. The actual number of
available retries is MAX_RETRY -1
This field was added in version 19.3 of the Intel Quartus
Prime Pro Edition software.
RSU_NOTIFY
5D 1 0
Clears all error information in the RSU_STATUS response and resets the retry counter. The one-
word argument has the following fields:
• 0x00050000: Clear current reset retry counter. Resetting the current retry counter sets the
counter back to zero, as if the current image was successfully loaded for the first time.
• 0x00060000: Clear error status information.
• All other values are reserved.
This command is not available before version 19.3 of the Intel Quartus Prime Pro Edition
software.
QSPI_OPEN
32 0 0 Requests exclusive access to the quad SPI. You issue this request before any other QSPI requests.
The SDM accepts the request if the quad SPI is not in use and the SDM is not configuring the
device. Returns OK if the SDM grants access.
The SDM grants exclusive access to the client using this mailbox. Other clients cannot access the
quad SPI until the active client relinquishes access using the QSPI_CLOSE command.
Access to the quad SPI flash memory devices via any mailbox client IP is not available by default
in designs that include the HPS, unless you disable the QSPI in HPS software configuration.
Important: When resetting quad SPI, you must follow instructions specified in Resetting Quad
SPI Flash on page 158.
QSPI_CLOSE
33 0 0 Closes the exclusive access to the quad SPI interface.
