MSP430F5418A：Updating Application Firmware with the MSP BSL , I meet some problems.

Hi,

can you please check if you have set your data model to medium or large in the project settings? The small data model only allows using the first 64k of memory. Please see screenshot below.

Here's the description of the data model:

Best regards,

Thank you for your reply.

I set  the data model to medium or large ，but still not erase correctly.

the erase code as follow：

//erase code

void FLASH_Erase(void)        
{
unsigned int Adr;
Adr=0x6C00;                              //erase code 1
while(Adr<0xFDFF)
{
FLASH_EraseSEG((unsigned int *)Adr);
Adr+=0x0200;
if(Adr%0x1000==0)
SCI_Tx('*');
}
Adr=0x10000;                           //erase code 2
while(Adr<0x16000)
{
FLASH_EraseSEG((unsigned int *)Adr);
Adr+=0x0200;
if(Adr%0x1000==0)
SCI_Tx('*');
}
}

//erase one segment---one SEG is 0x200 (512 Bytes)

void FLASH_EraseSEG(unsigned int *Address)
{
_DINT();
FCTL3=FWKEY;                                 // LOCK = 0
while((FCTL3&BUSY)==BUSY);    // Waitint for FLASH
FCTL1=FWKEY+ERASE;               // ERASE=1
*Address=0;                                    // Write to the SEGment
FCTL1=FWKEY;
FCTL3=FWKEY+LOCK;
while((FCTL3&BUSY)==BUSY); // Waitint for FLASH
_EINT();
}

when  run the  erase code 2，it will go wrong 

Thank you for your reply.

the question about erase flash solved.

I have another question.

the address of the app code :0x6c00-0xfcff 0x10000-0x16000
xcl file of the app:
-Z(CODE)INTVEC=FC80-FCFF
-Z(CODE)RESET=FCFE-FCFF

is that OK？

the jump command is asm("mov &0xFCFE,PC;");

but when the programmer jump to the app code , it can not run correctly.

I can sure the app code is written to the flash .

I need to ask another question .

the address of the app code :0x6c00-0xfcff 0x10000-0x15736
if I change xcl file of the app:
-Z(CODE)INTVEC=0x15F80-0x15FFF
-Z(CODE)RESET=0x15FFE-0x15FFF

Then how to jump to the address : 0x15FFE ?

thanks !
