+ Calypso has 256KB of internal SRAM (0x800000-0x83ffff, although some of
+ this is, I believe, actually ROM). Only this internal SRAM is used by
+ these configurations. The internal SRAM is broken up into two logical
+ banks.
LRAM (rw) : ORIGIN = 0x00800000, LENGTH = 0x00020000
- TRAM (rw) : ORIGIN = 0x00820000, LENGTH = 0x00010000
+ HRAM (rw) : ORIGIN = 0x00820000, LENGTH = 0x00020000

- Code can be loaded by the bootloader only into TRAM and, hence, is restricted
- to 64KB. The additional 64KB if IRAM may be used for uninitialized data and
- for the NuttX heap only.
+ Code can be loaded by the CalypsoBootloader only into HRAM beginning at
+ address 0x00820000 and, hence, is restricted to 128KB (including then
+ non-loaded sections: uninitialized data and for the NuttX heap).
