 From my findings Luminary is Cortex-M3 based, in which case there's 
needed a base code RTL for it. FPC will generate code for it, and it 
should generally work, but it's not very optimized yet(other than 
generic optimization), and there are many unsupported inline assembler 
instructions(primarily special system instructions). But there are 
ofcourse workarounds for the assembler code

Currently there's only half working stub code for the STM32F103 
Cortex-M3 based chip, but I'll gladly help if you have any questions
