Hi,

how to change application code to start at addres @4000 ?

Because on the BLS Scripter i am having an issue about the address :

[ERROR_MESSAGE]Invalid address!

And if a manually change the default address @0000 to @4000 the BSL Scripter can flash the MSP432E401.

Here is my application .txt output format setting:

Here is my application .txt code:

And here is the example txt application from BSL Scripter:

Another question, do i have to fash the bootloader first than the application right?

If the start address from the application lets say is @4000, will it affect the boatloader which should be at address @0000 ?

Best regards,

Michael

On the "MSP432e401y.cmd" file i could change the APP_BASE Address to 0x00004000:

*****************************************************************************/

#define APP_BASE 0x00004000

    FLASH (RX) : origin = APP_BASE, length = 0x000FC000
    SRAM (RWX) : origin = 0x20000000, length = 0x00040000
}

}

__STACK_TOP = __stack + 512;

This changes the main address on flash but i the debugger doenst put a breakpoint in main().

I cannot start the program code and in the disassembly it stays here:

This is what the debugger verbose output:

CORTEX_M4_0: GEL Output:
Memory Map Initialization Complete
CORTEX_M4_0: Flash Programmer: Verbose output enabled
CORTEX_M4_0: Flash Programmer: DLL Version 3.3.0.1
CORTEX_M4_0: Flash Programmer: Found illegal reset vector address
CORTEX_M4_0: Writing Flash @ Address 0x00004000 of Length 0x00001068

CORTEX_M4_0: Flash Programmer: Programming flash memory
CORTEX_M4_0: Flash Programmer: Write speed 34.5 kB/sec
CORTEX_M4_0: Flash Programmer: Exit flash programming

Any idea? Do i have to change anything else?

Ok i made it to work now.

On project propreties i set the debug flash settings as followed:
