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 there. > Is the mod loaded to RAM and executed?

This leaves us less RAM for audio data buffering. /Linus Received on 2001-12-17 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
