- The time taken for Board_driversOpen is mostly for the PHY tuning of OSPI. If this needs to be further reduced, one can pre-train the PHY, note down delay values and set it directly instead of the tuning procedure.
- MCU PBIST is started before the DDR init/ It is done in HW in parallel while the DDR init is completed. Due to this MCU PBIST wait time is low.
- The time taken for Sciclient Get Version can be avoided if the version check is disabled
