Dear expert

Nobody has an answer and will post again.

I want to create a custom bootloader.

How can I create a custom bootloader?

TI bootloader has a fixed address of 0x080000, so I understand that it is not possible to divide the project into two.

So, in my opinion, I'm going to make it by Flash.

How can I divide Flash?? Do I need to create two main() function?

Or can it be divided into functions and stored?

If it is divided into functions, the RAM area should also be divided into Bootloader and application. What should I do?

Please give me some advice

Thanks and best regards,

Edward

Edward,

I would start with this app note http://www.ti.com/lit/sprabv4 and specifically section 5 that addresses the dual core nature of the F28377D, essentially CPU1 will need to enable CPU2's bootloader. There are reference to code examples in C2000Ware here(you may need to navigate up or down depending on what you require).

Let us know if this is the right direction to address your question.

Best,

Matthew
