MCU-PLUS-SDK-AM243X: How to differentiated or identify SBL at 0x0 and 0x40_0000 from OSPI bootflash

Hello,

Please have a look at the following thread

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1304243/am6442-boot-backup-mode-selection-in-case-of-qspi-primary-boot-mode

As an example, the following test function extracts the relevant information from the xSPI parameter table

void test_func() {
    uint8_t* active_boot_table_ptr = NULL;
    uint32_t active_boot_table_index = *(uint32_t*)0x701BEBFC;

    if(active_boot_table_index == 0x0) {
        active_boot_table_ptr = (uint8_t*)0x701BEC00;
        DebugP_log("Bootmode: Primary\r\n");
    } else {
        active_boot_table_ptr = (uint8_t*)0x701BEE00;
        DebugP_log("Bootmode: Backup\r\n");
    }

    DebugP_log("Peripheral: %d\r\n", *(uint16_t*)(active_boot_table_ptr + 4));

    uint32_t read_index = *(uint32_t*)(active_boot_table_ptr + 292);

    if(read_index == 0) {
        DebugP_log("Boot offset: Primary @0x%x\r\n", *(uint32_t*)(active_boot_table_ptr + 296));
    } else {
        DebugP_log("Boot offset: Redundant @0x%x\r\n", *(uint32_t*)(active_boot_table_ptr + 300));
    }
}

Attached are the logs when the test function is integrated to SBL NULL:
