Since the flash size is 256K, I suspect that the code that
loads the firmware from disk and puts it into RAM expects it
to be less than 256K as well.

I would guess that the maximum mod size would be about 250K, since
the flash code sets the stack pointer at 250K from the start of
RAM, and I assume that the loaded firmware is put at the start
of RAM at 0x9000000, since the exception vectors are located

Correct. The flash is not updated. This leaves us less RAM for
audio data buffering.
