Someone pointed me at this page: http://wiki.freepascal.org/TARGET_Embedded And I started adding a device (and perhaps more after that), starting with a cortex-m3 though which is thumb/thumb2 only. Following the instructions on the page work fine: fpc -Parm -Tembedded -Wplpc2124 tled1.pp Added my device as well as tried the two other cortex-m3 devices and fpc -Parm -Tembedded -Wpdevice test.pp I tried -Parm, -Pthumb, thumb2, cortex-m3 but it just keeps generating arm instructions. I can certainly target an arm processor first but would rather try a thumb/thumb2 first.

Actually I would prefer thumb first then thumb2 cpuinfo.pas does not have an architecture tied to thumb but the cortexm3 and armv7m can be easily moved to thumb temporarily or create say a cpu_cortexm3_thumb in the tcputype list, etc...
