Charles, Thank you for the information. So Thumb compiling and assembly is handled by tc and ta respectively while 5l can handle linking both thumb code and arm 32. I guess my next question is: does this mean Inferno can run on certain Cortex-M micros since it can run MMU-less? (provided enough memory of course) And has this been done before? ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tc22ac8ae61456f10-M2c24d5ce248578623d7a097a Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
