I forgot about the NoInit section!

No, since the Bootloader and Application will never be running at the same time. The device will perform a Soft Reset when branching from the Application to the Bootloader and vice versa, i.e. calling the ResetHandler which will load the variables needed by the bootloader/application and overwritting the old ones.

Thus, you will have 6kB RAM - 0x80 bytes (NoInit Section) = 0x1780 bytes RAM that the application can use.

I think the bootloader and the application could use the same RAM space as they run at different times. So, I think you could get 6K.
