Quote:I was wondering, does anyone have a memory map for the PRIME and the OS?

Not a full memory map, but most of it is in the S3C2416 datasheet anyway.
Gathering full memory map information may work from inside a full-custom third-party firmware, and getting it out of the calculator is best done through either the RS232 TTL port or one's own character drawing routines.
Custom third-party firmware in armfir.elf does not run entirely bare metal, as evidenced by the fact there's still some base code running at a deeper layer, which enables one to turn the calculator off and on (but lose display contents).

Quote:Note that our CPU supports Jazelle (runs java bytecodes in hardware).

AFAICT, Jazelle is largely undocumented, and therefore unused on most ARM926EJ-S platforms in the real world. On the TI-Nspire, which also uses an ARM926EJ-S, Jazelle support was never used beyond a test program which confirms that the CPU actually supports Jazelle, as indicated by the CPU flags.
