It should be possible to build
PhoneME MR2 for Coldfire.
The basic build needs some basic assembler functions to glue java calls to C calls.
The more advanced build involves the JIT compiler, and that would be hard: all the example code is written for Arm cores.
On the
twiki page there's valuable documentation on how to port PhoneME to new cores.
The link to how to build it for
Freescale iMX.31 applies to the LTIB toolchain for coldfire.
