J721EXSOMXEVM: Regarding Access of OSPI flash sectors during OSPI boot up mode

Tool/software:

Hello Team,

we are using the MCAL package MCUSW_09_00_00_15_CONFIG + ti-processor-sdk-rtos-j721e-evm-09_00_00_02

When we are integrating SBL and tifs.bin from TI and booting from OSPI, as we see below SBL is flashed at offset zero of OSPI , tifs.bin at offset 0x80000 of OSPI and App image at offset of 0x100000 of OSPI , so our doubt if we are accessing these many areas of OSPI then even application also needs some flash area to access it for its operation. In Fls confifuration, the Fls sector address is always start address of OSPI , So OSPI start address overlaps with SBL which already present. In this Case, how to resolve this Issue?

Hello Karthik,

Thankyou for looping Autosar Expert.

we have another query, when we debugged SBL and our application together, we got know that already OSPI init is called in SBL of Ti and also our application will call Fls_Init which internally Calls OSPI Init.

May i know, how we can avoid this?
