Thank you for your response.
As I have been reading trough the forum and documents, evaluation boards come with a flash with Redboot. And then, this loader lets you put kernel image in RAM or even in flash.
But, since we are using a custom board, we will have an empty flash. Is there any way to program the flash in a custom board with Redboot?
I have been searching for a tool called "HAB_toolkit". Is this suitable for this purpose?
Thank you very much.
