TMS570LS3137: 4 Binary files 4 project to be working on single bank of 1.5 MB

Good Day Mr.QJ Wang ,

Project 1 is supposed to be CRC verifier and decision maker this project 1 will have TABLE of function pointers to pass control at an EXCEPTION for PROJECT 2 ( beginning at BANK0 0x00020000), PROJECT 3(Beginning at BANK0 0x00100000) and PROJECT 4 ( Beginning at BANK0 0x00120000).

Project 1 will be fixed and should never be erased for any reason during life time of the product so 0x00000000 to 0x00020000 , is supposed to be Fixed project that never gets erased and this project contains decision to pass the Program Counter to Project 1, Project 2, Project 3 OR Project 4 . When the CRC is confirmed for those projects the control jumps to those projects .

When Project 2 CRC is good and control is passed to Project 2 it is dependent on Project 1 to pass the exceptions to this project 2 , Project 2 is totally independent from Project 3 and Project 4 .

Project 3 is independent from Project 2 and project 4 but from Project 1 the exceptions will be redirect to Project 3.

Project 4 is independent from Project 2 and project 3 but from Project 1 the exceptions will be redirect to Project 4.

FIXED DECISION MAKER address             0x00000000 to 0x00007FFF

UPGRADEBLE APPLICATION address      0x00020000 to 0x000FFFFF

BOOTLODAER APPLICATION address      0x00100000 to 0x0011FFFF

UPGRADEBLE DECISION MAKER  add    0x00120000 to 0x0015FFFF

Psuedo code for _undef EXCEPTION that will be fixed and never be erased at address  0x0000004 

void _Decision_Maker_Table_undef(void)

       g_ul_Interrupt_TransferAddress= APPLICATION_BASE_ADDRESS+0x04UL;
       ((void (*)(void))g_ul_Interrupt_TransferAddress)();
}
else if(Region_Active==0x424F4F54)
{
       g_ul_Interrupt_TransferAddress= BOOTLOADER_BASE_ADDRESS+0x04UL;
      ((void (*)(void))g_ul_Interrupt_TransferAddress)();
}
