Hi Renan,
the error message shows "Error: selected processor does not support Thumb mode `cpsie i'"
I didn't see your project, but I ever had a customer met similar when porting project from CW to KDS.
they fixed the problem by creating a new KDS project then adding the user files part by part.
`cpsie i'" can work with KE06 under KDS without problem.
FYI, this is a document of how to use inline assembly.

Have a great day,
