TMDS64EVM: Flash_reset before CA53 run.

Part Number: TMDS64EVM

Tool/software:

Hello TI support team.

I'm using mcu_plus_sdk_am64x_09_01_00_41 with AM6422.

I'm starting CR5 and CA53 from SBL OSPI,
However, I would like to run Flash_reset before CA53 boots (CA53 is booted by Bootloader_runCpu).
Is this possible?
The reason is that when CA53 starts, the flash is initialized,
so I want to do Flash_reset on the SBL side before starting up and finishing it.

The specific SBL OSPI (main.c) code is as follows.Is this procedure correct?

            /* Run CPUs */
            /* Do not run M4 when MCU domain is reset isolated */
            if (!Bootloader_socIsMCUResetIsoEnabled())
            {
                if(status == SystemP_SUCCESS && (TRUE == Bootloader_isCorePresent(bootHandle, CSL_CORE_ID_M4FSS0_0)))
                {
                    status = Bootloader_runCpu(bootHandle, &bootImageInfo.cpuInfo[CSL_CORE_ID_M4FSS0_0]);
                }
            }
            if(status == SystemP_SUCCESS && (TRUE == Bootloader_isCorePresent(bootHandle, CSL_CORE_ID_R5FSS1_0)))
            {
                status = Bootloader_runCpu(bootHandle, &bootImageInfo.cpuInfo[CSL_CORE_ID_R5FSS1_0]);
            }
            if(status == SystemP_SUCCESS && (TRUE == Bootloader_isCorePresent(bootHandle, CSL_CORE_ID_R5FSS1_1)))
            {
                status = Bootloader_runCpu(bootHandle, &bootImageInfo.cpuInfo[CSL_CORE_ID_R5FSS1_1]);
            }
#if 1 // after
            /* Load the image on self core now */
            if( bootImageInfo.cpuInfo[CSL_CORE_ID_R5FSS0_0].rprcOffset != BOOTLOADER_INVALID_ID)
            {
                status = Bootloader_rprcImageLoad(bootHandle, &bootImageInfo.cpuInfo[CSL_CORE_ID_R5FSS0_0]);
            }
            Flash_reset(gFlashHandle[CONFIG_FLASH0]);
            DebugP_log("Flash reset done\r\n\r\n");
#endif // after
            if(status == SystemP_SUCCESS && (TRUE == Bootloader_isCorePresent(bootHandle, CSL_CORE_ID_A53SS0_0)))
            {
                status = Bootloader_runCpu(bootHandle, &bootImageInfo.cpuInfo[CSL_CORE_ID_A53SS0_0]);
            }
            if(status == SystemP_SUCCESS && (TRUE == Bootloader_isCorePresent(bootHandle, CSL_CORE_ID_A53SS0_1)))
            {
                status = Bootloader_runCpu(bootHandle, &bootImageInfo.cpuInfo[CSL_CORE_ID_A53SS0_1]);
            }
            if(status == SystemP_SUCCESS)
            {
#if 0 // before
                /* Load the image on self core now */
                if( bootImageInfo.cpuInfo[CSL_CORE_ID_R5FSS0_0].rprcOffset != BOOTLOADER_INVALID_ID)
                {
                    status = Bootloader_rprcImageLoad(bootHandle, &bootImageInfo.cpuInfo[CSL_CORE_ID_R5FSS0_0]);
                }
                Flash_reset(gFlashHandle[CONFIG_FLASH0]);
                DebugP_log("Flash reset done\r\n\r\n");
#endif // before

                status = Bootloader_runSelfCpu(bootHandle, &bootImageInfo);
            }
            /* it should not return here, if it does, then there was some error */
            Bootloader_close(bootHandle);
        }
    }
