Hi,

I'm making FLASH booloader using f2803x_flash_kernel project in controlSUITE.

f2803x_flash_kernel is RAM based project, but I need FLASH based bootloader.

So I convert from RAM to FLASH. This is allocated in FLASHA sector.

Downloaded application run after downloading in f2803x_flash_kernel .

But in standalone mode (JTAG is disconnected), Application doesn't run.

In debugging mode (JTAG is connected), Application run after downloading.

The last code is 'return SCI_Boot();' in example.

SCI_Boot() returns entry point of application.

What is difference between JTAG and Standalnone mode?

I changed source code as shown below.

void (*ApplicationPtr) (void); // This is already declared in the example.

ApplicationPtr = SCI_Boot(); // change from return SCI_Boot();

ApplicationPtr();

It runs in any mode (JTAG and Standalone)

But I'm not sure that it is correct.

Is this the correct method?

I am afraid that your thread is off-topic here. This is msp430-related forum, not f2803x.

I don't understand your reply.
This is C2000 releated forum. And my question is releated C2000.

One basic thing to check is BOOTMODE pin setting on the board. BOOTMODE pins should be set to BOOT from Flash.

BOOTMODE pins are always set to BOOT from Flash.
