I have an application in FLASH. I want it to be able to download a program to SRAM and then execute it.

What traps or pitfalls do I have to think about?

I have previously made a bootloader that calls a main program in FLASH memory.

Do I call a program in SRAM the same way?

It's going to run quite a bit slower then when running in FLASH

Hi sima, obtronix,

Thanks for the comments, Note also to remap the interrupts into RAM if you them in your application. Running program from RAM is useful for user boot-loader applications or to program the Internal flash as well.

Cheers,
